Aqara temperature sensor problem: it goes instantly to 0ºC and comes back to normal

Hi all,

I am having a problem with Aqara temperature sensors. I have Mariano’s edge driver, but this happened also before edge.

The issue is that they goes to 0ºC and come back later to normal readings, some times instantly, others after a while. This is a big problem because I have some automations depending on their readings to turn on a heater or a ceiling fan, depending on the temperature. So, now that is hot during night, it turns on the heater during night.

Attached some pictures of the behaviour.

Any idea of why is this happening and how to fix it?

Many thanks!

I can’t tell you how to prevent the bad reading, but you may want to add a time threshold to trigger your automations. For example, trigger if the temperature had been < x° for 5 minutes.

This is what the Aqara sensor sends during recurrent reports, and this is the reason why it’s not certified :slight_smile:

In my driver I just ignore zero values if the previous reading is much higher. It enables normal indoor use.

Hi @Elendal

I hadn’t seen the post.

I will implement a correction as @veonua has done in his driver

Very nice. These false readings create havoc and chaos!
