Hello all,I'm currently performing a ZHA migration from my old zigbee coordinator (a slae.sh CC2652) to a SLZB-06M and even if it looks successfull at first, no devices are reachable anymore. I'm getting "Failed to perform the action switch/turn_on. 'message_type'" when I try to interact with any zigbee device and they start to be unavailable one by one :/ Any idea/lead ?
#ZHA coordinator migration issue from CC2652 to SLZB-06M (EFR32MG21)

I rolled back for now but extracted debug logs and diagnostics.

Did open a zigpy issue for it: https://github.com/zigpy/zigpy/issues/1577

puddly did find the issue. It was a bug impacting previous older version of the core. Upgrading to the last core version did fix it. Thanks again @wispy citrus ! Awesome work and support as usual 🙂

I'm glad you've migrated to a better coordinator!

It was needed. I was never able to get a stable situation with last koenk firmwares for the CC2652. So at one point, let's migrate to a coordinator that is now stable and well supported by the HA team 🙂
