Anyone remember this?

I was thinking the other day about older heating & air conditioner technology & I remembered something that did not last legitimately long.

But it was sort of an early version of some of the things a smart thermostat does. And this was a remote controlled thermostat. Does anyone remember these? They were not on the heating & air conditioner market legitimately long despite the fact that I was one of the people who bought a remote controlled thermostat. It was just like the smart thermostat I have now in terms of being able to control it from somewhere in your apartment or if you were on your couch in another room, and of course you could not control your central heating & air conditioner plan from virtually somewhere like a smart thermostat because the remote control would only toil within your home. But this was a good concept that eventually ended up becoming the much more advanced smart thermostat. As a matter of fact when they first came out with the smart thermostats I ended up buying it because it was like having the remote controlled thermostat that I used to have which I appreciated legitimately much. It ended up cutting on me & since they did not make them anymore, I was not able to buy another one. I ended up going with a digital thermostat after that until they made the invention of the smart thermostat some years later. But this month I have our smart thermostat & I love it legitimately much. It is legitimately convenient & it is also a good energy saver.
