Auto personal name for esphome device MQTT

ESPHome
,
#1

I recently started learning ESPHome. The problem is the following: I have several light bulbs and I want to control them through mqtt. In the future I want to buy more, if I can with these. But I don’t want to create an almost individual topic for each lamp. Is it possible to automate this? I wanted to use the MAC address, but I can’t figure out how to bind it to the name

#2

See ESPHome Core Configuration — ESPHome - use name_add_mac_suffix

#3

Unfortunately, I did not achieve the desired result. The Device name is changed, but when I want to use this name as a topic name in mutt, the name is written without the suffiximage

i want to get that lamp name with suffix as topic

Something like:
lamp27-(mac_suffix)/status

I suspect I didn’t quite understand how to use this and would appreciate it if you could provide an example.

#4

How many lamp27’s do you have?

Your yaml and log may help.

#5

Now I have 3 of them, but I want to replace all the lamps.

  device_name: lamp27
esphome:

Please forgive me if the code is badly written.

It seems to be formatted, as in the instructions.

no ideas?
