Is it possible to set entity area via python script?

Configuration
1

Hello everyone,
I have a whole bunch of entities for which it is forbidden to set the entity via yaml (e.g. MQTT entities).
Rather than going through all of them 1 by 1, I was wondering if it is possible to set their area via python script?

All of these entities have their area in their entity_id anyway, so it is easy to find them in the UI, but it is a pain to set them all via the UI.

I thought that a script would solve this in milliseconds but I am not sure if HA allows this and if so, how it is done.

Thank you all once again for your support! :slight_smile:
Alex

If you want to hack this, you can just edit the entity registry file in your .storage directory (do backup before!). But I wouldn’t think it’s worth the hassle and possible errors for that one-time job.

Well, it is not a one-time job. Everytime I add a new Shelly or other MQTT device, I have to do it.
Everytime I wipe my HA setup (or setup a new test system), I have to do it.

I don’t know why it is not allowed to simply do this in the MQTT yaml file, but it is simply not allowed. And manually editing the .storage directory is too risky and far more work than having a python script run through all entity_ids and then setting the area according to the id.

I’m looking for exactly the same thing and for the same reasons. The name of the area is often in the name of the device and it would therefore be easy to deduce via pyscript to which area to assign it… so if you find a lead, I’m all ears.
