Yes I read in a comment if there will be any possibility to add all these smart devices to Heatbit Heater later?
You know too well there was never such a comment, the whole situation is pretty simple, you still believed you were in some art contest like the pumpkin one, overreacted to the news, and added some
features. Why not say it? You believed this would be cool so you decided to add them on your own, just as there was no comment, you didn't commit any crime by photoshopping that and you don't need to find some alibi for it!
Even if it is true, why would that be an upside if you can just use a regular coffee/speaker that cost less and probably more reliable? At the end of the day if you want to buy something like this your goal is probably to mine BTC, not for owning an all-in-one electronic device.
I would say that the goal here is to offset power costs, more like getting cheaper heat than actually using this to mine bitcoins for your won stash, although in my opinion it quite fails even at this. As for the other stuff, of course there is no upside, we don't have right now a heater that makes coffee and has speakers that sells in thousands, right? So if this kind of thing is not produced it means there is no market for it, and adding a bitcoin miner on top of a product that doesn't sell won't make it more attractive either. That's why they aren't planning on doing it either.
