I think it still track. If they expect something they will say and realtor will put in buyer contract. esphome is probably better/more reliable than any device you would purchase from store/web.
I also have belief that buyer in this category rips and replaces(want very specific) or just wants working and dont care the details very much (inspector will mention if it looks like problem and recommend replace with non smart) .
buyers vary and there is no pleasing everyone.
