Home Assistant Core >= 2026.2.0 requires HACS update to Ramses RF >= 0.54.2

[Edacs-Andre]

After upgrade to Home Assistant Core (HA) 2026.2.1 the Ramses RF integration show no data anymore. The EVOhome templates aren't working after this update so it seems that we need an update for the Ramses RF integration also before updating the HA core to version 2026.x.x.

I'm using the latest version of Ramses ( 0.53.2) in Home Assistant.

I had to restore a previous backup to HA version 2025.x.x to receive data again.

Well, I just found Ramses RF version 0.54.0 in HACS so I updated this and after HA Core to version 2026.2.1. EVOhome is working again fine now. Strange thing is that there wasn't any announcement inside HA that Ramses needed to be updated to the latest version because of a HA core update. After updating to Ramses 0.54.0 in HACS, I still see in the HA Settings-Devices and Services that the Ramses Intergration shows version 0.53.6 even after a full reboot of the HA Server. Strange...

yes, version issue is related to #482

Will leave it open as another way - besides the HA User Forum - of informing users to update Ramses RF.
Original (same) issue #481 was already closed

Version 0.54.1 does not work for me, ha 2026.2 (docker image) and ramses rf 0.54.1 updates values once on start but than hardly any updates for hours, flatliners on all valves, even changes of setpoint do not happen. But after restore, still on ha 2026.2 (the one with the nice new overview page) and through restore ramses rf 0.53.2 and that is running stable updating every few minutes. So my advice is to make backup before going to 2026.2 and/or ramses > 0.53.2.

Version 0.54.1 does not work for me,

@msteenhuiz Can you add some context? Any errors in the HA system log? You run Heat or HVAC? Via MQTT or USB? With SQLite MessageIndex Option on or off? Attach your schema and 0.54.1 packetlog.

Version 0.54.1 does not work for me

@msteenhuiz Assuming you run CH (heat), see issue #495: Update to 0.54.2 via HACS
