No OTA in zigbee2mqtt

Thought this was supposed to be better than the old version. However this one doesn't have a temperature reading like the old one. This one touts OTA update howeverzigbbe2MQTT says OTA is not supported. Not sure where the benefits are seen? No doubt still way better than the comparable SonOFF devices.

Little Sensor that just works.

I use these on all my exterior doors. They are dead simple to install. Battery lasts about 2 years. And they are rock solid using Zigbee.
