>> That being said, if I was ever to leave home automation hardware behind, it'd be a "if you want to pay x on top of the already agreed upon price for the property, I'll leave it", where x is the cost for me to just buy new modules for my new place. If you live in any major urban center that request would likely get laughed at since the value of your depreciated hardware likely wouldn't even count as a rounding error on the purchase price. Some buyers might even want a discount on your selling price because of the extra work they'd have to do to get rid of the gear.
