I’ve recently upgraded all of my Blue switches and dimmers from version 2.0 to version 2.15 firmware. Discovering that the parameter/entity list is quite different between these versions. Is there a way to update the associated parameters/entities in HA without removing and readding each switch? Using ZHA here.
I believe your best bet is going to be to remove/readd the devices. Fortunately with Zigbee they should remember the device/entities, etc and when you remove the device it goes straight into pairing mode, so you’ll be able to discover them right back. I’d still probably do 1/time and make notes of the entity names if you have them tied to a lot just in case. Especially with everything that changed between 2.00 and 2.15, I think that’s just going to be the simplest option in the end.
