Unneeded entities through MQTT Auto Discovery

Configuration
1

Some of my devices, especially smart plugs with power monitoring, created a boatload of entities through autodiscovery that I’ve since realized I don’t need. They were also automatically added to Lovelace using the suggested cards because I did not know better.

Is it benign to leave them and just take them out of Lovelace or are there benefits (reduced network traffic perhaps) to taking them out of the “system” as a whole?

If the latter, how do I go about it? I suspect I have to do it in HA, the MQTT broker and possibly in the Tasmota-ized devices that are publishing to the associated topics.

Thanks

There’s a very minor processing advantage to disabling the entities. Not something you would notice unless you have thousands of them. It would reduce your recorder database size slightly too.

Just removing them from Lovelace is fine.

You can disable entities via the configuration / entities menu. (Click on them).

Thanks for the guidance!
