I have 2 TEMPer USB sensors pluged in in the same Server.
Now i wanted to change the name of both Devices, unfortunately i just can change the name of the first. The second device gets the same name like the 1st including “_1”
Look in your states dev tool (icon at bottom of sidebar of web interface). That’ll list your entity_ids. Those devices will have separate ID’s. Use a customize: block to set friendly names.
And note that customize is a child of homeassistant:
A common mistake is to treat it like its own platform.
Hmm. I wonder if there’s an issue with the way you’ve set up the sensors in the first place. It seems odd that they’re showing up as “unnamed_device” in the first place. Could you post your configuration for them?
