OTA update of Danfoss thermostat 014G2461 fails after adapter disconnects

[35gh]

What happened?

I've tried to update my Danfoss thermostats to 01.28.0008 01.28 from 01.20.0008 01.20.

Update is quite long (roughly 80 min).

Update fails almost all the time, apparently due to Zigbee2mqtt disconnecting from my SLZB-06M coordinator. Failure can happen at any time (10%, 70%, 99%...).

• With v1.35.1, update was failing with "Update failed with reason: 'aborted by device'" error, but adapter has disconnected before according to the zigbee2mqtt uptime in the SLZB web interface
• With v1.25.2 I now get the error "Adapter disconnected, stopping"

I tried to factory reset my thermostats, restart the devices by removing the batteries as advised, restart zigbee2mqtt with the same result. I even changed the Zigbee channel and had to pair all my devices again. I was however able to complete the OTA update for 3/8 of my devices with v1.35.1 after countless retries.

OTA works for other devices.

Connection to SLZB-06M is rock solid if I'm not using OTA. It stays connected for days. I've also pinged the adapter for hours from the docker host without any packed drop.

What did you expect to happen?

OTA update work without failing

How to reproduce it (minimal and precise)

Check for an OTA update Restart the device by removing / inserting the batteries and connecting again to the Zigbee network Wait for a cooldown period Launch OTA update.

1.35.2

+1 Just bought the device yesterday (new one with G) - eTRV0103 Firmware build date 20230914 Firmware version 00.20.0008 00.20 What is strange I have different imageType - "288"

debug 2024-02-06 15:20:40: OTA: Got upgrade end request for '0x048727fffe1416da' (eTRV0103): {"status":149,"manufacturerCode":4678,"imageType":288,"fileVersion":28} debug 2024-02-06 15:20:42: OTA: Update failed with reason: 'aborted by device'

+1 Can`t update LYWSD03MMC on 1.35.3. Same error. Downgrade Z2M to 1.34.0-1 and OTA update completes fine.

+1, sort of.. I'm having what appears to be the same issue but with an entirely different device. I am trying to do an OTA upgrade on an Inovelli Blue 2-in-1 switch. I posted about it over in their community. See my details over there.

Perhaps this means it's not an Inovelli issue, but instead a zigbee2mqtt AND/OR SLZB-06M issue.

LMK how I can be of assistance with this issue.

Downgrade Z2M to 1.34.0-1 and OTA update completes fine.

I just read that part of your post and downgraded z2m and my Inovelli switch updated just perfectly.

Good to know it CAN work.

After downgrading the add-on to 1.35.1-1 update went successfully. Or not exactly successfully cos I hit this unfamous bug when firmware ver showed as AAAABBBBCCCCDDDD Followed steps as per guide below (one missing - press allow join after starting Z2M) and it solved the issue https://github.com/Koenkk/zigbee2mqtt/issues/11049#issuecomment-1072349455

I've updated to 1.36.0 and was then able to OTA update 5 Danfoss thermostats without any issue. I guess the issue can be closed.
