Fully local smart thermostat - works with Home Assistant!

Good, not great. Seem slow to recognize temp and shut down air handler. GeoFencing messes it up.

I solely bought this thermostat because it is capable of operating fully locally and integrating with Home Assistant via the Homekit integration (note: this does NOT actually require an Apple device, since Home Assistant acts as the Homekit server). I replaced three ancient mercury bulb thermostats ... Read more

I could just about drop kick this "smart" POS.

Reviewed in the United States on July 12, 2023

What can I say, it is a thermostat and it looks nice, I bought it for these reasons. I bought it in April of 2023 right after I had a leak repaired and the old thermostat looked very dated in a freshly painted room.

It installed very easily and It really does look nice and new in the roo...m. Once up I was pretty happy with it. I set a schedule and that's where the enjoyment stopped. As time went on I began to wonder if I had a leak or something, I had one in the past after all. It would not cool, and the temperature in the house would rise. I'd set it to 71 but the temp would slide degree by degree to 77 (which is what it was scheduled to hit at 11pm) and stay there for the night. Suddenly waking up freezing in the morning. The pillows in the bedroom were muggy and damp intermittently. Some days we'd sit at 77 degrees for no reason. The heat pump is running near 24/7 trying to cool the house....

Luckily I am pretty DIY and troubleshooting for hobby so I bought gauges to monitor my unit and learned what Superheat and subcooling are. I determined that I don't have a leak! So what is it? I have an energy saver cycling box from the power company, I have that taken off, it takes a few weeks for them to do it. but my problem persists! I'm going mad, inject dye to search for leaks? I change filters, etc etc. anything i can. I'm debating draining the unit, perhaps the repair guy put in too much or incompatible oil!

I begin to suspect the thermostat, all the internet says it couldn't be the thermostat, no no It could never.. But I say I say you know what let's reset the thing and strip away features. So I did, Reset it, turned off scheduling, wifi, and anything else "smart", got into the special menu and found "adaptive recovery" looked it up and determined this and scheduling were my problems! Because I wanted 72 from 8am to 5pm but the 77 at 11pm. The stupid "smart" algorithm thought that meant I want to be 72 in 8am and for the rest of the day slowly drift to 77 by 11pm and then freeze us half to death at 5am to be 72 again by 8am. If I set my schedule to all 72 degrees it will never leave 72 even on a "hold". I assume because of crap programming that adaptive recovery does not take into account the "hold" or manual input/changes which is bullcrap.

I decided to see how badly programmed this algorithm was. I put a schedule on with crazy temperatures like 50F at 8am and 90f at 5am or something. The stupid thing would actually turn the HEAT ON to after 8am so that it be 90F by 11pm even though the cool setting was set to be 50F at that time. what a dumb program. Heating when it should be cooling!

I was smart enough to figure this out and disable these features, I won't even use the schedule now Im too afraid too Which is same because I really wanted to let the AC drift off temp at night but its not worth it to trigger the "smart" alogrhtium's stupidity which seems to have the ability to override your manual temperature settings even without being turned on. I see no where to fully disable this "smart" features.

I feel bad for anyone that calls HVAC specialists to try to fix these issues and they get talked into the a whole new system because of some programmers' poor programming skills. Read more

I would save your money on the new ones and just buy the refurbished models in these that they sell on Amazon. They would likely work just as well. I got the new ones for 75 on prime day. The refurbished ones sell for 60 all the time.

They work for the most part. Setup is fairly simple. G... Read more

Unit died in 9 months, Wifi setup very odd, really bad support

Reviewed in the United States on July 29, 2021

First, I was struck by how very strange the wifi setup was, where you have to go to the router and turn off your home wifi, and create a wifi specially just for the unit itself, then let it find that wifi, I mean, I am a technical person, it's what I do for a living, computer stuff, I've seen all so...rts of strange things, and this was really odd. It certainly not the turnkey experience the average user would expect.

I've been doing electronics as a hobby for many years, I've put together computers and 3D printers. So having said that, the T5 was difficult to wire up, no intelligent wiring like some other smart thermostats, the online intelligent tech support gave up when I told it what wires I had, even though when I read how to install manually on third party sites I didn't see issues. Couldn't get a Honeywell support person who could help me either, very much a disappointment there. Honeywell support seems almost nonexistent or at least heavily overtaxed to the point that they cannot support the user base.

But a little online reading on independent forums, connected a few wires, and I was there. And it hooked up to the app fine, and ran fine for nine months, from October 2020 to July 2021.

Then one hot summer day out of nowhere we notice the heater has suddenly started up full blast! I went to check the T5. It had no display and appeared to be not working. I pulled the Honeywell T5 off the wall and checked the wires, no shorts or crossed wires. Turned the entire hvac system off, put the T5 unit back on the wall, turned it all back on, same issue. Tried hitting reset on the hvac units and again, the T5, no display, no wakeup from touch screen, unit was dead.

As far as I can tell the T5 is, with no warning, no error messages, just completely bricked.

So I disconnected it and hooked my old non smart thermostat I had (luckily) saved (just in case) back up and everything went back to normal. Super frustrating. Ugh. And I've been told by an HVAC person that all of their customers with Honeywell smart units report that the Honeywell smart thermostat customer support is a nightmare; I've dealt with nightmare support enough in the past, I will not in the future.

I guess the giant corporation Honeywell got my money, and that's their main concern- that first time new purchase. Well, from me it's goodbye forever Honeywell. I've heard good things about other smart units, I will look into one of those instead. I feel like I've wasted a hard-earned $115+ dollars on this smart thermostat and it's really frustrating.
