I’ve ended up deleting a few devices for a variety of reasons.
Most recently I deleted my coffee maker, as that detection stopped working after my sensors were moved in the panel. But it was re-detected by Sense in a few days. This was great!
What I’d really love is to be able to merge this newly detected device with the deleted device so that historical data is combined.
I’m also planning to replace several appliances in the future, so I’d like to merge new with old for similar reasons.
