Sonoff Temp/Humidity sensor only getting Humidity?

Greetings

Recently bought and paired a Sonoff Temperature and Humidity Sensor(SNZB-02) with my C7 (2.2.7.126) and it paired easily (using the Sonoff Zigbee temp/humidity type) and at pairing I got temp, battery and humidity info. Since then I get regular %RH (humidify) updates - but I get no temperature updates. The temperature has definitely changed enough that it should send updates.

Any ideas/suggestions would be greatly appreciated.
Thanks

Normally I'd suggest running "Configure" on the device page to make sure the device is configured to report properly, but I'm pretty sure these things sleep and won't respond to one. This command also runs during pairing, when the device would definitely be awake, so you could try resetting and re-pairing the device (don't remove it from Hubitat first; it will recognize it as the same device, and you won't disrupt any apps using it that way, though either way would work). Hopefully the device will hear it the second time around if it didn't get it the first time and thus caused this problem.

Otherwise, I suppose it's possible you have a faulty sensor or the reading hasn't really changed enough to send a report, but mine seem to send on every 0.4 degrees F change (not sure if this is configurable; it isn't in the driver preferences).

My best guess from looking at my logs ... Temperature updates at the latter of (0.5C change) or (5 minutes).

I most typically see changes of 0.5C (0.9F). During times of fast transients, I may see bigger changes of 1C or 1.5C (1.8F or 2.7F), but no faster than 5 minute increments.

So, introduce a very significant change - maybe put it on a Ziploc bag that has a couple of ice cubes. If no report after 15 minutes, then something is faulty.

You can try my driver here GitHub - dlmcpaul/HubitatDrivers: Collection of Device Drivers for the Hubitat IOT Hub

It will allow you to reconfigure and will wait for the device to transmit before sending the reconfigure commands.

Thanks all for the suggestions! I tried what [bertabcd1234] recommended and it did start reporting temperature after that - and has continued as expected for over a day now.

[dlmcpaul] I am going to give your driver a shot too as I am adding a few more of those devices and others.

Thanks
