I haven't seen this, but will keep my eyes peeled.

@swa72 v3.1.0 is very old, there are a lot of fixes since that, also the wrong warm water prefix in ha has changed to ww. Please update.

[swa72]

Hi, my bad. Will do. Hopefully, this does not end in a big rename orgy of entities in HA ;-) Am Mi., 22. Sept. 2021 um 09:54 Uhr schrieb MichaelDvP < ***@***.***>:

Do I have to reset anything in MQTT?

[MichaelDvP]

These are old mqtt entries with retain-flag. You have to remove them from mqtt-broker.
Best way:
1 power off emsesp
2 remove all emsesp entries from mqtt-broker
3 power up emsesp again

[proddy]

Michael is correct, these are the old names and need to be removed manually. I've been exploring how to get EMS-ESP to clean up old MQTT topics (I'll create a new issue for this)

[swa72]

Ok, removed the messages using MQTT Explorer (HA and EMS-ESP were still running). Rebooted HA. All clear :-)
