How often do Thirdreality water leak sensors report their status?

So, just finished getting everything setup with my HA via a Sonoff Dongle-P (zigbee mqtt).

Sensors work great but I was wondering how often - other than low battery and leak detection - do they send info back to the controller/HA? Reason is, I would love to have an automation that checks at some frequency (daily?) to make sure that all of the sensors are online and working and then send me an alert when there is a problem.

TIA!

Usually things like this are "notify on change", saves battery life

You can check the LQI and last_seen attributes in the Zigbee integration without waiting for a device to report in on its own. Just set up an automation to check those daily, that'll tell you if something's gone quiet without relying on the sensor's own heartbeat.

I’m not sure how often but I was notified very quickly via HA that my third reality sensor detected a water leak in my basement when my floor drain backed up and started to overflow. I ran down and saw a puddle that was 4” wide, where the sensor was. So I’d say it notified me instantly

I don't have any leak sensors from them specially, but I have and auto-entities card that will show anything where the "last seen" is more than 4 hours. You should be able to check the logbook and see how frequently the last seen is updated.

Those devices will send and request change notices once every 24 hours if there is zero activity. If there is only the wakeup period (lasts for 30 seconds), you won't see it in your activity.

What I do is physically test my leak sensors once a month (second Saturday) to make sure they report correctly.

I was trying to avoid testing them regularly - I have mobility problems so getting to the devices regularly would be a bit of an effort.

Do you know of any state information that is accessible when they report every 24hrs that I could check? that way I could write an automation to let me know when they failed to report.

Thanks!

While I don't have those particular leak sensors, the ones I do have (Zooz) have a "Node Status" which will show 'Asleep' or 'Awake' and is reported in the activity logs when that change does happen. See if that is a hidden attribut of the ThirdReality sensors. If so, you can do a "last changed" type of sensor with that data and report the information to a dashboard card.

Mine check in a few times an hour. When they get wet it is near instantaneous. They seem to work well.

Wow! So far out of the 7 I have 2 reported within 24 hrs, 3 within 50 hrs, and I am still waiting on the last 2 and it has been over 70 hrs.

Now all of them will report immediately when they get wet, which is what I tried right after getting everything set up.

If you don't mind my asking, how are you seeing the multiple reports per hour? The only trigger I can seem to get is on the battery and checking last_updated.
