I don't think you're getting it, and a lot of us around here want you to. If I were actively researching heat pumps (a thing most homeowners do before dropping 4-5 figures on ANY hardware), if you are locking me into your ecosystem -- or even have the appearance of locking me into your ecosystem -- your product is not getting onto any short list from me or likely anyone else around here.
All of us -- every tech person who has ever gotten into home automation in a real way -- has thrown out some hardware rendered useless by a company. We've already seen this play out. You're an unknown and so are the riskiest kind of company to buy into.
You need to get this -- deeply -- if you want to sell to this market. The pull quote above makes me want to run for the hills.
I’d honestly just try to market to heat pump believers first who actively are looking for what they are selling. First, it’s an easier sales pitch. Second, they will be more forgiving of growing pains. Go through the 1-3 years trying to get the manufacturing, maintenance, and installation locked in before trying to sell in bulk to a larger market.
As it is, it’s just too risky for many to buy. (And for my house, it would be impossible to install).
