Alexa will do it if you have the a smart thermostat. But you'd need to figure out how to enter your other address.

We're getting fiber optic cable and I have no idea how to use it other than the internet. Lines are dug and buried and already to the house, it just needs to be hooked up.

We have a Nest thermostat at both homes - primary and vacation. I like the ability to raise or lower the temperature from anywhere. The 'Away' temp at our vacation home is set at 60 in winter and 85 in summer. I can easily change it from my phone app. I can also schedule different temp settings, check to see how much energy is used daily, check both the inside and outside temperature, and inside humidity.

Two years ago In February I checked the Nest at our place in upstate PA I noticed that the Nest claimed it was heating but the inside temperature was around 55. I raised the temp setting by 5 degrees, the Nest showed that it was still calling for heat but the temp never went up. A sure sign that the furnace wasn't working. We called our contractor who inspected the furnace and said that it wasn't heating and was able to repair it. Our security system has a low temperature alarm that notifies us if the inside temp drops to 50. Fortunately the temp hadn't dropped that low.

If we're going to be away from home for a few days I'll lower the temp in the winter - no need to keep an empty house at 70 degrees - but before heading back home I can reset the temp to what we normally keep the house at. Same procedure for summer.

We replaced the furnace at our primary home 5 years ago when we moved in and the new HVAC came with a Nest thermostat and a free Nest doorbell. I find both of them enormously convenient.

We have a Nest at our vacation house. I leave it on ECO temp when I'm not there. The heat goes on if it's below 50 in the house, the AC goes on if it's above 85. When I'm there, I manage it via my phone. I really like being able to manage the settings from my phone, check the usage, etc. I warm or cool the house before I arrive. It also alerted me that the filter needed changing-pretty nice! We also have one in our primary house. The one problem is that if the wifi goes out, the nest goes out? Thankfully, that hasn't happened much and wifi has been quickly restored. It works as a manual thermometer if wifi goes out.

We have Nest and overall it works well, but it is difficult to manually manipulate if you do not have the app.

We have an Nest on each floor of our current home. Because my husband is a tech guy he is obsessed with these things. A couple of years ago he was out of town in July, checked the thermostat and found that the 3rd floor (guest room only) was 80 degrees. There was a problem with the duct work. Not as bad as a freeze, but we were blowing cold air into the attic for days. I like that we can turn the heat up as we are traveling home from a trip so the house is nice and toasty when we return home.

Ecobee is the brand. We have two at our primary home. We can control the temp on our phones from anywhere. This year we will install one at our weekend place .

Yes - we've had one for many years. We actually have two at our lake place and one at home - all are the same to keep it simple for programming, the phone app, etc. Ours are Honeywell Focus Pro 6000. There are much newer, fancier models but this does everything we need and has performed flawlessly - the oldest one is probably 15 years old. It notifies us if the temperature drops or exceeds the level we have programmed and indirectly if the power is out because then it can't communicate with wi-fi. That problem has been solved with the whole house generator however.

We have a Nest system at our getaway home. It's worked very well for us. It's nice that we can turn up the heat/AC before we get up there and the house is a nice temperature when we arrive.

It's also saved us a couple of times when our propane supply ran low. My brother-in-law is a bit OCD about checking the temperature in the winter months (a good OCD thing!) and saw that the heat was on but the indoor temperature was too low. The propane company is supposed to fill our tank on a regular schedule but "forgot" us one time. The other time was when we were hit with the polar vortex and burned through fuel faster than usual.

We also have Ecobee and have been very happy with it. Easy to set up and easy to use. Nice to arrive to a warm house in the winter!

We have a caretaker who is pretty good about "wellness checks" for the house, and it is not like it goes that long empty. Just seems like a good idea. Thanks, all.
