Wrong firmware version displayed

[Diaoul]

What happened?

Zigbee2MQTT is showing outdated firmware information on paired devices:

Not working :-1:

1. I had a Legrand 067773 paired to zigbee2mqtt showing version 0x2a
2. I removed it and paired it to the Legrand Gateway, it's now showing version 0x46 (70 in decimal)
3. I removed it and paired it again to zigbee2mqtt, it's showing the incorrect version 0x2a

Sometimes, it happened that I updated some devices outside zigbee2mqtt and when I paired them again they were still showing old firmware information.

Working :+1:

Now if I do the same thing, but shut down zigbee2mqtt when the device is not paired anymore, it works:

1. I had a Legrand 067773 paired to zigbee2mqtt showing version 0x2a
2. I removed it and paired it to the Legrand Gateway, it's now showing version 0x46 (70 in decimal)
3. I stopped zigbee2mqtt then started it again
4. I removed it and paired it again to zigbee2mqtt, it's showing the correct version 0x46

:point_right: Obviously I don't want to do that for all my devices :grimacing:

What did you expect to happen?

The correct firmware version is displayed without the need for a time-consuming exercise.

How to reproduce it (minimal and precise)

This would be hard to reproduce... However, I'm interested in knowing when is a firmware version refreshed from the device? It smells like a cache invalidation issue.

@Koenkk could this be causing other issues like on checking firmware versions online and missing out on potential updates? :thinking:
