I had setup custom entity_id’s for my Z-Wave and IKEA Tradfri devices and it was working quite well. However yesterday they all suddenly reset to their default names. Since I have a lot of the same devices, it is quite hard to tell them all apart now and I have to figure it out again.
Earlier that evening I setup MariaDB instead of SQLite and also changed the batteries on some of my Z-Wave nodes if that makes a difference. Late last night I did a reboot, since HASS seemed unresponsive. After the reboot, the entity_id’s and custom names were suddnely gone.
So my true question is, how is this possible? And how can I avoid it in the future? ie. what is the correct way to customize these entities?
