Quick feed back on the following devices bought on AliExpress:
List item Smart LED GU10 Bulb, AC100 - 240VAC, Zigbee Protocol - It works 100% with iHost and seems reliable.AliExpress Link
List item Smart Soil Sensor (NAS-STH01B) Zigbee Protocol - It paired with iHost, but there is no data/ information coming through. I think you need the Tuya Hub, but if anybody out there has a work around, kindly let me know. AliExpress Link
I have a few purchases on the way and will be testing them soon.
I have never seen smoke concentration and this information is not in the log.
But smoke detection shows. And the main thing for me is there is a loud sound on the smoke sensor and on ihost, and the Scene on iHost is also working and smart sockets are turned off when smoke is detected
