How did this end, any solutions? I have the same issue, i made a reset two days ago, but now the problem is back. No update of temp the last 17 hours, and there has been about 10-15 degrees celsius difference.
My sensors update very random but all in general about every 15 minutes, but sometimes up to 2-3 hours. No explanation why. I have reinstalled the firmware i homey and I think that improved all zigbee devices.
I also have this issue with Aqara temperature and humidity sensors. Sometimes temperature updates ever 5 minutes, sometimes it takes over 60 minutes to update. Sometimes humidity is updated but not temperature… Very strange and irregular, doesn’t matter if it’s a sensor 2m from Homey or 20m.
