Help all my Xaiomi LYWSD03MMC no longer working

Configuration
1

After I think an update several weeks ago I just noticed that all my Xaiomi LYWSD03MMC are no longer available.
I went to devices and found the ble_monitor . But now says it can’t run now with an error message. I poked around in it but now the app itself is missing and I can’t reinstall it. If anyone can help me I’d be most grateful. I’m not very savvy in changing the config files but I think the problem is there?

I’m going to guess the error message said it was due to solar flares and you should cover everything with tin-foil.

That was a joke.

Tell us what the error message is (exactly, word for word) or we are only guessing.

Try this: [Bug]: Installation fails with "config flow" error · Issue #895 · custom-components/ble_monitor · GitHub

Thanks but That’s not any help it’s like a hundreds pages of discussions on multiple topics none seem related to how to fix the Passive BLE Monitor app.

Perhaps someone else can help me?

I linked you to an exact post with some options to try:

Try to remove and reinstall it, restart HA and hit F5 a couple of times

Wasn’t there mention of these devices in a recent breaking changes section of a software update release notice? You know - the ones you ready very closely before hitting the update button.

I have no logical way to know how I got it so working again but most likely by buying a couple more non flashed Xiaomi BLE thermometers and flashing them and also setup two new zigbee thermometer devices that when installed also fixed the older existing problems. Not a clue how or why. But it's all working again. Sigh
