Disable the deCONZ All group - dresden-elektronik/deconz-rest-plugin Wiki

Source: https://forum.phoscon.de/t/ecodim-4-channel-switch-not-functioning-properly/140/30

Doing this will help cases where you have a switch that for some reason controls every mains powered device in your house.

1. Shut down deCONZ

2. Open the sqlite DB (zll.db) located in your deCONZ data directory

$ sqlite3 zll.db
SQLite version 3.27.2 2019-02-25 16:06:06
Enter ".help" for usage hints.

3. Set the All group as deleted

sqlite> update groups set state="deleted" where gid="0xFFF0";

4. Exit sqlite3

sqlite> .exit

5. Start up deCONZ again

6. Reset and repair the switches in question to finally cease usage of that unwanted group
