Third Reality Smart Switch Gen 3 (3RSS009Z) reporting much lower battery level after 1.39.1 update

[loafbutts]

What happened?

Hello! I have four Third Reality 3RSS009Z switches set up in Z2M. Yesterday, all four were reporting battery status in the 40-50% range. After updating to 1.39.1, all are now reading 12-16%. The switches typically start flashing their physical low battery lights in the low 20s, and none of them are currently doing so. I also tried swapping a completely fresh set of batteries into one of the switches, and it only showed 16%. In addition to the sudden drop, these factors lead me to believe it is a change in reporting rather than the batteries actually being that low. I only have one other battery-powered device on my network, and its Z2M battery status did not change like the 3RSS009Z ones did. Thanks!

What did you expect to happen?

Battery status for 3RSS009Z switches would be the same as it was before the 1.39.1 update.

seems it's a problem converting: zhc:tz: Read result of 'genPowerCfg': {"batteryPercentageRemaining":139}

Should be fixed now!

Changes will be available in the dev branch in a few hours from now. (wait 24 hours before the sensor reports a new battery % value)

This is back to normal with the latest Z2M update. Thank you very much!
