Anybody getting an error when changing operation mode of water heater in 2025.11.10-beta?

[MrEarl]

I'm getting the error
Write error: Strategy SimpleVer does not match ['SemVer'] for 1.77
when changing the operation mode of the water heater.

It happens if I change it in the UI (message is displayed on the bottom of the screen).
If I change it in an automation, an error is raised, stopping the automation (using continue_on_error: true as quick workaround).

Nevertheless, the operation mode does in fact change to the desired value - it's the error in the UI and in the automation that bothers me.

@MrEarl Can you go to config/logs, and see if there is more information about the error in the system logs?
Please post any additional information here.

I cannot reproduce this error. For me changing the operation mode of the water heater works ok.
Can you go to the water heater device in HA, and let me know what is listed after "Firmware: " in the Device Info section?

[MrEarl]

Thanks for looking into this issue!

Firmware in device info is V1.77
I've just tried it again and this is the error in the system log.
Attached you will find the log of the integration when I first encountered this issue.

Hope this helps. If you need something else, just let me know.

Same here with v1.76. occurs by changing operation mode for water and also heating. When i rollback to 2025.10.8-beta it works fine.

[rhammen]

Thanks, the logs were very helpful information.
I have merged a PR to main that should fix the problem!

[MrEarl]

Yes, it fixed the problem. Thank you!
After upgrading to the latest version, the error in the UI is gone and the automation runs without the workaround.

[rhammen]

Solved, so closing this question.
