Hi, After trying to update two of my LYWSD03MMC sensors, both gave me a failed message in the Homey App when trying to wake the devices. I tried reinserting the batteries, but the updater continued to wait, and then eventually failed. The devices are now unavailable to Homey, and shows a BT icon i…

Hi,there is no need to wake up the sensor based on my experience…what firmware you are on and what was it trying to update to, any debug logs ? Tried reset yet and re-adding to Homey ?

Yes, I’ve tried resetting and readding. I was on version 1.1b0 / 3.0b1 (information from Homey), and trying to update to 7.9b153 / 3.0b1. This was through Homey’s own OTA functionality.

Sadly, no. I was mainly wondering if you or someone else had encountered something similar and had a quick fix. Otherwise, I guess I will find a way be starting from scratch with converting them back to Zigbee.

I have the exact same issue. Did you find any fix? Thankfully I didn’t update all my sensors at once:sweat_smile:

I wonder which sensors on which firmware version…

[image] The model is lywsd03mmc. I actually got it to work after re-inserting the battery a couple of times. I will try some more sensors

For me I didn’t have to reinsert batterie nor wakeup the sensor, it was quick smooth update for me frankly, naturally I got sensors close to Homey.
