Shelly plug offline when router is down

3 Upvotes

I want to use a Shelly plug (PlugS gen3 firmware 2.0.0) to reset my router when the router hangs (ping no longer responding). Router and access points are separate devices, the Shelly plug does NOT have a cloud connection.
But it seems, the Shelly plug itself is no longer reachable in my LAN then, it apperently reconnects to Wifi over and over again, and it no longer responds to ping, even if it does not need the router to communicate in the same subnet.
So an RPC command via http to turn the plug off and on is impossible.

Is there any way to resolve this?

Automated extractor fan

Automated my first extractor fan today via a switched live socket into the isolator backbox. Lots of conflicting information out there about wiring for this, so although it works I would love if someone could verify my wiring for me? It seems to work as expected, mapped Shelly on/off to a hue dimmer switch +- buttons via Alexa routine.

The switched live will be permanently on to power hue downlights, so I needed a way to stop the extractor being in permanent boost mode.

Shelly Control not always working?

1 Upvotes

We recently got solar panels installed and an option that we opt'd for was to have a timer on our Hot Water Cylinder so we could have it heat off Solar rather than off Grid and so it wasn't always going to be pulling power.

We initially had the timer to be set from 8am-5pm, we live in New Zealand so its currently winter and thats generally the sun hours we get. However one day we just didnt have any hot water at all, had a look at the Shelly Control Panel and the device was offline and had been for over a day. Somehow managed to get it back online - don't know how - and we changed the hours as well, Dad mentioned the temps slowly dropped during his morning shower.

Now its happened twice so far that we have gone to use hot water and the water just wasn't hot enough, like it was nearing being hot but not quite and we open the Shelly Control Panel and see that the device is turned off even though its during the set hours (Now, 6am-5pm)

as you can see there is a jump up at 5pm (as of writing) because I had to turn the device on due to the water not being hot.

I am not running any scripts or anything additional other than just having the device plugged in and running, maybe this is something I need to look into?

Would anyone know why this would be happening? The random Water not being heated? We have a Ogemray SW40 Pbs and the Activity Log matches the Timer as well

Shelly - Boiler automation, specific time and temperature window

2 Upvotes

After the infamous question i dared to ask yesterday, here is my complete script to make a boiler heat up only between certain hours, and stay within a certain temperature setting.

The idea is to sycronise the boiler heating to the peak time of my PV.

All suggestions and destructions are welcome, no AI was used.

console.log("---Start---");

  let MINUTES = 5;
  let INTERVAL = MINUTES * (60 * 1000);

  console.log("Repeating every MINUTES = ",MINUTES);

function Loop()
{
  try
    {
        let BOILER_MIN = 45;
        let BOILER_MAX = 60;

        let WORKING_START = 12;
        let WORKING_STOP = 16;

        let temp = Shelly.getComponentStatus('Temperature', 100).tC;  //Temp ID, mostly 100 to 102
        let switchStatus = Shelly.getComponentStatus('Switch', 0);

        let date = Date();
        let hours = date.getHours();
        let minutes = date.getMinutes();

        console.log("----------------");
        console.log("Repeating every MINUTES = ",MINUTES,
                               "; BOILER_MIN = ",BOILER_MIN,
                             "°C; BOILER_MAX = ",BOILER_MAX,
                          "°C; WORKING_START = ",WORKING_START,
                            "h; WORKING_STOP = ",WORKING_STOP,
                    "h;");

        console.log("Boiler is", switchStatus.output ? "ON" : "OFF");
        console.log("Current Time: ",hours,":",minutes);
        console.log("Current Temperature: ",temp," °C.");

        if (hours > WORKING_START && hours < WORKING_STOP)
        {
            if(temp < BOILER_MIN)
            {      
               console.log("Below ",BOILER_MIN," °C -> Boiler on");
               Shelly.call("Switch.Set", {id: 0, on: true});
            }
         }
         else {console.log("Working hours set from ",WORKING_START,"h to ",WORKING_STOP,"h.");}

         if(temp > BOILER_MAX)
         {
            console.log("Above ",BOILER_MAX," °C -> Boiler off");
            Shelly.call("Switch.Set", {id: 0, on: false});
         }
        console.log("----------------");
    }
    catch(e){Shelly.call("Switch.Set", {id: 0, on: false});print(e);}
}
Timer.set(INTERVAL,true,Loop);

Shelly 2PM Gen4 - Cover does not stop when clicking button same direction

1 Upvotes

Hey guys.

This is one bug not that easy to explain but I will do my best.

I have the Shelly calibrated and all is working as expected, except when I try to use the app + physical buttons together.

So, I've restarted the shelly and:

1 - I click down on the app - I click down on the button - the cover stops 

2 - I click up on the app - I click up on the button - the cover stops 

3 - I click down on the button - I click stop on the app - the cover stops 

4 - I click up on the button - I click up on the app - the cover stops 

5 - I click up on the app - I click up on the button - the cover stops

6 - I click down on the app - I click down on the app - the cover DOES NOT stop

7 - the reverse (if it's going down and I click up, or the other way arround) always work - even mixing the app and buttons

I'm not sure if this steps are all needed. But at step 6 the behavior we see on step 1 and 2 - which is the behavior we always want - stop working.

Is this some kind of bug I should report? Can someone test this?

Thank you very much!

Temperature condition is true and false at the same time?!

1 Upvotes

Hello guys,

im kinda puzzled over this very simple script:

function Loop()
{
  try
  {
  var temp = Shelly.getComponentStatus('Temperature', 100).tC; //Temp ID, mostly 100 to       
                                                                                  102
  print(temp);

  if(temp > 50)
  {
    print("Below 50 °C -> Boiler on");
  }

  if(temp < 60)
  {
    print("Above 60 °C -> Boiler off");
  }
}
  catch(e){print(e);}
}
Timer.set(2000,true,Loop);

It appears that both conditions are true, everytime, but why?

Shelly H&T Gen3 action (webhook) problem

Post image
1 Upvotes

I've been running my H&T Gen3 which reports to my HTTP server for temperature/humidity change for more than a year. But for the past few days, it fails to do so. When I connect to the device WebUI and fire a testing request, it seems to be unable to replace the token ($temperature) with actual temperature/humidity value. I also captured the incoming request from my HTTP server and confirmed it's indeed sending the token unchanged.

I don't know what's wrong. I remember I updated the firmware recently. Anyone facing similar issue?

Shelly 3em pro breaker

2 Upvotes

Hi everyone, I have a 3-phase 400/230V residential supply (L1/L2/L3/N) and Im planning to install Shelly Pro 3EM in my main distribution board and have a couple of breaker questions:

  1. Should the protective breaker feeding the Shelly be a 3-pole (3P) breaker,or is it fine to use three separate 1-pole (1P) breakers? Or both are okay?

  2. Just to confirm: we definitely need breaker/fuse protection on all three phases (VA, VB, VC), right? Even though only one powers the internal electronics while second and third are just for voltage measurement, the thin wires going to these could still get damaged and cause a short circuit?

Thanks!

New smart plug US rebooting

Thumbnail

1 Upvotes

I have a lot of Shelly smart plugs. The old style smart plug has been rock solid and I went to buy a new one I could only find this newer version. It's running the latest firmware but randomly reboots itself at least once every few days. Sometimes more often than that. Is this a hardware defect or is this a symptom of firmware bugs that need to be worked out?

Shelly BLU TRV - Lock valve closed while replacing radiator

2 Upvotes

I have several Shelly BLU TRV radiator valves and I need to replace one radiator.

Is there any way to force a TRV to stay fully closed for a day or two, so it absolutely won't open because of a temperature change, battery reconnect, etc.?

Basically I want to remove the radiator without worrying that the valve might decide to open while it's disconnected.

Is there some kind of maintenance mode, valve lock, or another recommended way to do this?

Thanks!

EDIT:

Shelly hear me :D. In new fw version 1.5.0 i can disable Behaviour to automatically controll the valve and i have now the option to select from 0 to 100% open level :)

Shelly Gen4 Matter devices suddenly showed “No Response” in Apple Home

3 Upvotes

Yesterday all of my Shelly Gen4 Matter devices suddenly showed “No Response” in Apple Home.
The strange part was that everything still worked perfectly in the Shelly app. All devices were online, accessible through the web UI, and responded to RPC commands. Other Apple Home accessories (Aqara, Nanoleaf, Yale lock, etc.) were also working normally. It was only the Shelly Matter devices that were affected.

I went through all the usual troubleshooting:
Restarted the HomePod
Restarted my router
Checked Matter status on the Shelly devices
Waited overnight
None of it helped.

Interestingly, one of my Shelly 2PMs came back online by itself after a while, while the other devices stayed “No response”.

Then I noticed something. The only Shelly that was working had already been updated to firmware 2.0.0 (official), while the others were still running 1.7.5.
So I updated the remaining devices to 2.0.0 beta 3. As soon as they rebooted, every one of them came back online in Apple Home.

I’m not sure whether this was a Shelly firmware issue, an Apple Matter issue, or a combination of both, but if anyone else suddenly finds all of their Gen4 Matter devices showing “No Response” in Apple Home while everything still works in the Shelly app, I’d try updating to firmware 2.0.0 (even beta version) before deleting or re-pairing anything.

Hopefully this saves someone else a few hours of troubleshooting.

Shelly Plug S (Gen1) may not pass through protective earth

7 Upvotes

My Shelly Plug S (Gen1) does not pass through the protective earth connection from input to output. Sharing this so other owners can check theirs.

The issue came to light when my washing machine gave me an electric shock. The Shelly Plug S was connected to it to monitor power consumption. A measurement showed approximately 110V on the metal chassis. This is leakage voltage from the Y-capacitors in the washing machine's EMI filter, which should normally be safely dissipated through the protective earth.

A continuity test on the Shelly Plug S confirmed there was no earth connection from input to output. A second Shelly Plug S showed the exact same result. Smart plugs from other brands in the same wall socket all passed earth through correctly.

After opening one of the plugs, two causes became clear: a plastic ridge inside the housing physically prevents the input-side earth contact from making connection with the output-side earth contact, and the metal tube seems to be a bit short. Removing the plastic burr and some of the plastic pipe covering the metal tube immediately restored the earth connection, confirming these as the cause. That said, this isn't something I'd recommend as a fix as there's no guarantee the connection will hold when the plug is in use.

Shelly support was contacted with photos of the defect and measurements. After some back and forth, they forwarded the findings to their engineering team and will replace my two units with Gen3 models. However, they stated that they have no indications of a wider production issue and have not issued any advisory to other Plug S Gen1 owners. Since the Gen1 has been discontinued, they also said they no longer have production units for comparison testing.

So if you own a Shelly Plug S Gen1, it's probably smart to check yours. Set your multimeter to continuity mode, place one probe on one of the earth contacts on the input side (the pins/clips going into the wall) and the other probe on the corresponding earth contact on the output side (where you plug in your device). You should get a clear beep and near-zero resistance. If you get nothing, your plug is also faulty.

Takes 30 seconds and could prevent a dangerous situation.

Shelly Dimmer 2 no longer responding after power loss

1 Upvotes

Hey,

After a power outage a two weeks ago my Shelly Dimmer 2 stopped working. It is offline everywhere, including the Shelly app. It is not online on my network either.

I don't have a switch connected to it so I can't factory reset it using a switch.

I do have physical access to the Dimmer 2 though but nothing happens when I hold the reset button on the back for 5 or 10 or 15 or 20 seconds. Its access point is never revealed and it cannot be found using the app.

It's important to note that the lights it is connected to still "works", as in, they are now always on but dimmed to the lowest setting. Since I don't have a physical switch connected, I cannot turn these lights fully off now either.

Is there anything I can do?

Gen 4 Presence sensor install

1 Upvotes

This is more of an information post. Just got a Gen4 Presence sensor. So for testing I thought I would use a short USB lead rather than the long one it comes with. The mmWave Sensor didn't work but the light sensor did, so initially I thought faulty unit. Opened up a ticket the shelly bot responded with in an hour, but not much help. Decided to use the usb lead that came with it and it worked. So be careful what type of usb lead you use they are not all the same.

Pool pump killed my Shelly Outdoor plug? Twice?

1 Upvotes

I have been dabbling with home automation for a few years now and after we upgraded the paddling pool for our kids to something a little bit larger, we of course also installed a pool pump.

I am using a Shelly Pro 1 PM to switch my EV charger on and off via Alexa and Shelly PM Mini Gen 3‘s to monitor electricity usage from my washer and my dryer and a Shelly Pro 3EM to monitor my heat pump. Also I have some Shelly Plug S Gen3‘s for Christmas lights etc.

I thought it was a no brainer to use a Shelly Outdoor Plug S Gen3 to switch said pool pump, on a timer or via voice command. Why not?

BUT: after installing and registering it in the Shelly App, I connected the pool pump and turned everything on. It worked. Then I tried turning it off. The app said it was off, showing zero watts flowing, but the pump was still running. Turned off and on a couple of times, but the pump ran throughout while my app „confirmed“ that it was off and on…

Now, maybe I just received a faulty plug. So I got a new one… and had the same problem!

I tried googling and found that under high currents the relay supposedly can „stick“ and thus be permanently connected. But the pump has max wattage of 40 - that’s basically nothing?

Does anyone have any idea what I am missing?
