Removing 1,700 devices (from RFXTRX) through core.* files?

[duittenb (Dirk)]

Team,
My RFXTRX was set to “Auto discover” resulting in >1,700 smoke detector devices with 8,500 entities.
Deleting these through the normal device GUI would take too long.

UPDATE 2023: I created an Applescript that removes devices by doing mouse-clicks: Can't remove 100's of RFXTRX devices - delete grayed out - #6 by duittenb

So I thought about deleting them through these files in the /config/.storage/ folder:

• core.entity_registry
• core.device_registry
• core.restore_state

I created a Python script that removes entries containing “RM174RF” from each of these files.
Steps:

1. ha core stop
2. backup 3 files
3. run script
4. core start

After HA startup completed both the core.entity_registry and core.device_registry contained the entries I just removed??

How can these items re-appear in these 2 files?
Are they also stored somewhere else?

Cheers!
DJ

I have the same question, did you manage to solve this?

Hello @benganellison

Check out this post. I created an Applescript (only working on a Mac) that automates clicks to remove the devices.

Can't remove 100's of RFXTRX devices - delete grayed out

Tobias, Sorry for the delay. I had to re-prioritize my ‘home automation’ time to help out friends. Here’s the script: # DJ: Script to remove 1700 devices from HomeAssistant # batch_count = batch size. Start small, then increase. At the end I used batches of 250 set batch_count to 1 set myDelay to 0.5 # myUrl = Is the browser still is on the right page? (security) set myUrl to "http://your_hs_ip:8123/config/devices/dashboard" # COORDINATE: select device set item_sel to "780,485" # COORDINATE: …

For windows you might be able to find similar software.
So far it’s the only solution I found.

Now I want to create something that shows the entity count for the RFXTRX integration and notify me if there’s > 100.
