Hey everyone!
I am running three Zemismart MTP1 Matter-over-Thread blind motors in Home Assistant, and the battery reporting is completely broken.
The battery level stays stuck at exactly 100% for months on end despite daily use. The raw Matter diagnostics show the motor’s firmware is actively broadcasting a raw battery percentage of 200 (which translates to 100%) and a hard voltage of 0V. This appears to be a firmware math calculation issue common to Tuya devices. Has anyone else experienced this exact 100% freeze with these Matter motors or found a known workaround to force them to report actual battery drain?
Thank you for your help!
