Home assistants MQTT show numerous entities twice

[swa72]

I have recently upgraded to https://github.com/emsesp/EMS-ESP32/releases/tag/v3.1.0, restarted the EMS-ESP device and had to configure it manually again. Didn't take too long. I noticed that there were a bunch of entities renamed - that's ok. But I found numerous entities that show up twice (with a "_2" postfix), here are two examples

• sensor.boiler_flame_current
• sensor.boiler_flame_current_2

Anyone an idea how to get rid of them? Maybe related to another issue. HA is complaining of

This came up earlier so #62 was created. In the meantime use MQTTExplorer to delete everything under homeassistant/*/ems-esp and restart EMS-ESP. HA will clean itself up.

Hhhm, I did run MQTTExplorer. removed everything

restarted EMS-ESP but the "_2" entities are still populated with data. Odd.

oh. not good. I just did a quick google on this and found

Looks like the solution is to delete the file .storage/core_entity_registry and restart HA. All valid entities will be recreated. Make sure you make a backup first though just in case!

[swa72]

Here is what I did

1. disabled MQTT on the EMS-ESP
2. removed everything from homeassistant/*/ems-esp
3. removed .storage/core_entity_registry
4. restarted HA
5. enabled MQTT on the EMS-ESP

great, if that worked I'll add it to the wiki. Thanks for trying it out

[swa72]

Well, there is one drawback if your remove the entity registry - all your entity names are re-created. If you have renamed them in the past, you'll have to do it again. And that is a PITA ;-/

Everything is back to normal - except "climate.thermostat_hc1" is missing (also hc2 and hc3). MQTT discovered all devices, I clicked the "ADD TO LOVELACE" button. Everything shows up except the climate controls. Per "https://bbqkees-electronics.nl/wiki/gateway/home-assistant-configuration-heating-circuits.html" I thought that I may need to add stuff for 2 and 3 manually. But 1?

that script from BBQKees is old. In HA you want to show all 3 climate controls and control them independently?

[swa72]

Exactly. They were present before the update to 3.0 but magically disappeared.

ok, I'll take a look.

[proddy]

@swa72 you don't see the thermostat in HA and MQTTExplorer like this?

[swa72]

Odd that. MQTT explorer shows them now

I just need to get them back into HA. Checked that and ... they are magically back. Huh?

Other than a couple of HA restarts I didn't do anything magic to make them reappear. I assume there must be some time for all MQTT message and hence devices to show up in HA before one does the "add to lovelace" click.
