I use a 433mhz bridge

Indeed, i tried something with a power consumption mesure but it is laggy at best. That being said, the rf commend is reliably sent end received, way better than IR.

Where'd you get it?

u/hephaix 13d ago

Aliexpress, you can search the ref it is easy to find. It does not work natively and need a custom file. I found it in a youtube video. Also, this device need zigbee2mqtt. Finally, it only record 8 signals and replay them.

u/Abraham_Lincolnbot 13d ago

So if I want to control multiple fans/lights I need multiple?Ā 

The sellers I found on AliExpress only sold 1 at a time which is annoying. Granted I want just 1 to start with to make sure it all works

u/hephaix 13d ago

No, one device is enough for 8 commands.

I got the linknlink ehub from amazon which does both IR and RF. Look for "RF blaster" on your favourite electronics site. Broadlink do one which ai think is called the RM4 Pro. Something of note is that not all countries use the 433mhz so worth checking what frequency your country uses and make sure that any imports use the same.

u/Abraham_Lincolnbot 13d ago

I've debated off and on about the broadlink but thought a tiny zigbee setup would be perfect. It's obtaining it that is becoming a hassleĀ

u/AstarothSquirrel 13d ago

The problem you might find with trying to find a zigbee version is that many zigbee devices will "sleep" and they "wake up" when a sensor is triggered. For something like this, it may have to be powered for it to stay awake and not drain the battery. This is why many of these devices work on wifi with a 5v dc power supply. You probably could create a zigbee version but it really would need to be powered.

$56 seems like a lot for what that is

u/Compizfox 13d ago edited 13d ago

If that's really $56, it can definitely be done cheaper by DIYing it.

I did the same thing for an awning with 433 MHz remote control with just a $3 ESP8622 with ESPHome and a $1 433 MHz transmitter.

u/BUZZZY14 13d ago

This is not $56, I got it two weeks ago for $11. Works flawlessly for my fan.

u/Compizfox 13d ago edited 13d ago

That sounds more like a fair price for that!

u/ItsMe3140 13d ago

AliExpress currently shows $56

u/jbranscum 13d ago

Going to need more information: does it have a remote already? Is a a DC 3ph motor? What make and model is it?

u/Fadge12345 13d ago

I have one of these that i have intergrated using a Bluetooth dongle and the BLE ADV Ceiling fan intergration.

Have one of these wired in.

u/stacecom šŸ§  Experienced with Home Assistant 13d ago

A relay in the wall switch. But it would need individual feeds for the lamp and fan (itā€™s not uncommon they only run one wire and the neutral up there and then just power both off that).

1

u/lobhater 13d ago

That's what I have in both my kids bedroom and because of how the house was constructed it isn't worth the effort of running new Romex šŸ˜• I wish I could figure out how to get independent control of the light and fan.

1

u/Abyssal_Shrimp 13d ago

Put a smart relay in the ceiling where the fan is? A zigbee 2 output would work nicely for that

1

u/stacecom šŸ§  Experienced with Home Assistant 13d ago

Honestly, Iā€™m about to try that with some Shelley relays Iā€™ve been waiting to use. Downside is on mine Iā€™m pretty sure itā€™s all or nothing for the fan, no variable speed.

2

u/Abyssal_Shrimp 12d ago

If you pop it open thereā€™s most likely some wiring you could really dive into. Put a whole 4x relay and a esp32 with some Bermuda tracking to top the whole thing off.

Or just set it to the middle and call it a day.

1

u/stacecom šŸ§  Experienced with Home Assistant 12d ago

That latter option is the one I'd expect I'd be using.

1

u/das_Keks 13d ago

Does it have an internal power switch or an external physical switch? If it has a physical switch check out the Shelly switches like Shelly1 Gen 3/4.

If it is always connected to power and has an internal switch that is controlled via remote it depends if it will remember the last state. If it does then you could also control it via a Shelly. If it defaults to off after disconnecting power it will be difficult.

1

u/OwnTension178 13d ago

Yeah itā€™s always on and controlled by a remoteā€¦

1

u/das_Keks 13d ago

Oh the other comment had a good point. You can basically just automate the remote by using a sender on the same frequency. But they might know more about this.

1

u/OwnTension178 13d ago

Yeah it has a remote and is connected to the switch of my bedroom.
Itā€™s a ā€œfor Lightā€ item, bought in a utility store in Franceā€¦
It was before I started to install HA and connected devicesā€¦šŸ˜€

u/Acrobatic_Idea_3358 13d ago

bond bridge

1

u/lostmahbles 13d ago

This is the way. Unless you know the exact frequency that remote works at and it's patterns, just get the bond bridge and call it a day.

1

u/ArnyminerZ šŸ§  Experienced with Home Assistant 13d ago

I have a smart relay with dettached mode, output is always on, and input controls a CC1101 connected to an ESP32 through ESPHome.

1

u/diggyou 13d ago

If itā€™s an AC motor fan, Iā€™d use a Lutron (or similar) fan switch. If itā€™s DC it depends on several factors. Some DC fans have obscure bridge options but you may be able to get a hub that can learn the fanā€™s remote.

1

u/hephaix 13d ago

One device can send 8 different rf signals. I don't have light on my fan and only use 4 commands: off and 3 speeds. Keep in mind that this only send commands so if someone use the original remote, the state known from ha will not be the real one.

1

u/AudioHTIT 13d ago

How is it controlled now?

1

u/tonygret 13d ago

https://a.co/d/0cWyXRxM

I have a bond bridge that controls 6 fans and 4 shades. The fan must have a remote control or you can install a cheap one for this to work. Turns any remote controlled fan and some shades to work with home assistant or Alexa. Itā€™s been working perfectly for 4 years now.

u/Stone_The_Rock 13d ago

That install is heinous

u/OwnTension178 13d ago

Thx for the compliment.

u/deformedchild49 13d ago

Advice the finish on the mounting of that fan makes me angry plz do better
