Aqara battery always 100% #87

Open Gobolin80 opened 1 month ago

HI, I have been using the Sonoff ZBDongle-E by ITead (now with this firmware https://github.com/darkxst/silabs-firmware-builder/blob/main/firmware_builds/zbdonglee/ncp-uart-hw-v7.4.2.0-zbdonglee-115200.gbl) on Home Assistant via the Zigbee2Mqtt addon, for a year. Everything works correctly except for the battery percentage, which for all 10 Aqara devices is fixed at 100%, even when the battery is completely empty. I don't know if it's a firmware bug, but I'll point it out.

This is what I see for a fully discharged device:

{ "battery": 100, "device_temperature": 25, "illuminance": 0, "illuminance_lux": 0, "linkquality": 216, "occupancy": false, "power_outage_count": 38, "voltage": 3115 }

Thanks for your work

Some Aqara devices are known to have issues with Silicon Labs firmware, probably due to Aqara devices not being fully compliant with the Zigbee Specs. Its possible the underlying SDK is missing some Aqara specific workarounds required to make things work properly.

I was afraid the problem might be something like this. Thanks for the feedback

ZBDongle-P does fair a little better with Aqara sensors compared to ZBDongle-E
