The AC company that just installed my new system today left about 2 hours ago. They attempted to install the Nest Learning Thermostat Gen. 3 on my old house without a common wire and failed. Left me with the old standard non-smart thermostat, which works fine, but dam, I wanted that fancy Nest one.
I really love the battery operated aspect of it which is why I decided to switch from the Nest to the Sensi ST55, but the Wi-Fi keeps dropping off despite that it was never a problem with my Nest and the router is only a few feet away. I’ve had to reconnect it at least twice a day in the last two days since I installed this thermostat. Furthermore, the app does not sometimes reflect what is actually going on at the thermostat itself, for example, it may be cooling, but the app looks like the thermostat is not doing anything and on standby. I hope Sensi somehow improves / updates this and I’d be all set.
I've had a Nest Learning Thermostat for a few years with no problem. Now the display goes blank and you have to charge it with a USB cable. After that it only works for a short time. I bought a 24 volt wire adapter for around $15 and have no problems now. Otherwise you have to run a wire directly to the heater which probably entails a professional.
We currently have a Honeywell round mercury thermostat. I’ve been following you for a couple years and was encouraged to buy a Smart thermostat. I purchased a Nest Smart Thermostat 2 years ago and haven’t installed it yet because of the common wire concern. Our home has oil boiler (radiator) heating with Beckett (model AFG series oil burner) and Honeywell (R4184 D 1027).
Hey James, our wires are heavier gauge, I verified it's not high voltage, only 27V across 2 wires at the really old Honeywell thermostat. What kind of wire can I use to make it a smaller wire so they can fit Nest? Does it have to be solid, or do I need to buy thermostat wire from Home Depot and use that? Thanks in advance, love your videos! PS: My old thermostat did not have R or W, just two unmarked screws.
Good video. We now have a basic Hunter 44110 thermostat that used 2xAA batteries. This thermostat will not operate without good batteries. Did you say the Sensi does NOT require batteries to operate?
Hi, my thermostat has blue, red and yellow. how should i go with nest thermostat installation please? i dont know what should i do for 4th wire. i can mail photo if you can look at and help me please. thanks
Google says they work without a c-wire, and it will for a few days, but then it gives you an error cause it doesn’t have enough power. Do NOT buy Google if you don’t have a c-wire.
Sorry but the Nest requires a S wire if you want to use it for more than 3 to 4 years. I installed 2 Nest smart thermostats 4 years ago and now the batteries have dies and they have to be replaced. When this happened I did a search and there are tons of folks complaining about this.
thank you for all this info, so helpful. I'm in a place where I can't use a c wire so will be trying the sensi you recommended! I got another sensi version previously but it required a c wire so sunk money there.
I had several Nest thermostats - I used them in heat only and AC only setups (not by choice). Great, right? NOPE - after 2-3 years they started to lose connection to my wifi - because the internal battery failed. And of course, Google want nothing to do with it - so now I have several hockey pucks. They don't repair or allow to replace the battery. So, I am nearly $1000 out. Thanks Google!
I have a Sensi thermostat and it’s a piece of junk, it’s very unreliable, the app constantly crashes and it’s completely useless !! I’m sorry I bought it !! If you’re looking for a new thermostat I DO NOT recommend buying any of their products !!

Ecobee 3 thermostat
@@devonrichardson2697 nope that needs a common wire also. Just tried to install mine.
Check with your electric company before you buy any smart thermostat.
Many offer free, or very discounted as part of an energy saving program.

You just wasted money. Nest thermostat needs C wire to stay longer than a day.

So what to get then
Facts. Sent mine back to Amazon.
Do any of these compatible with extra sensors?

You probably mean a C wire, but thank you. They must have internal rechargeable batteries....
Sorry yes I meant C wire. Smart thermostats being sold now are offering C wire adapters that are attached at the furnace control board. @@LiveHappy76
I have nest 3rd Gen. After 3 years not holding charges. Usles expensive. Need C wire.
Hasn’t the Nest E been discontinued? I think it’s difficult to find
Awesome thanks, what is the battery life for the Sensi? Can it control multiple zones with a remote sensor?
thank you for all this info, so helpful. I'm in a place where I can't use a c wire so will be trying the sensi you recommended! I got another sensi version previously but it required a c wire so sunk money there.
Why does he call the Sensi a "sensay." Is he the Karate Kid? Wax on, wax off...yes, Sensay!
Probably because it's close to the proper spelling of sensei
All these thermostats don’t allow users to adjust temperature swings (=maintenance band), so you will have short cycling issues
