Last time I was complicit in a factory reset, things didn’t go so well:
I’ve not yet tried the “reset data” option, but I imagine it simply wipes your data and all of your learned devices. I have contemplated that option, but so far I’ve only deleted devices (a poorly recognized water heater and heat pump). Mixed results there: the water heater was recognized again in a few days, though still has errors (and is still being “learned”), the heat pump was recognized again in a week or two, and I went from having two legs of the heat pump identified separately, and only 90% of the time, to both legs being identified as one device probably 95%+ of the time. No change in one case, improvement in the other.
I suppose I’ll give things another month or two before trying to reset my data…
