Perhaps you should explain the basis of your comment.

I personally installed four of these in my son's home alone three years ago, at least 2-3 of which were without a c wire. At the time I spoke to the Emerson Electric (mfr of Sensi brand and coincidentally local to where I live) technical support staff about their claim to not need a c wire (lots of other sellers claim no need but fail to point out that this means their devices rely on batteries which obviously die and usually at in opportune times). The technician's explanation was what I used in my post. It makes sense and I've read it online in other places confirming this. The units still work now and there's no way the batteries would have lasted that long.

Now that I've told you what I've actually done and my research with multiple sources, it's your turn to share with us. Have you installed one or more of these exact units? Did you call the manufacturer? Or do you just feel superior making negative comments? This forum is about sharing and helping others.

BTW, for anyone considering spending extra to get the color LCD version, be advised that model does indeed require the c wire. The one in the original post is monochromatic and it's simpler needs allows it to be operated without the c wire. If you wish to confirm, suggest calling the tech line. When I did, the wait time was almost non-existent, there was no labyrinth of menus to navigate, the technician was quite skilled, and their voice was easily understood. This was pre-pandemic but I hope that hasn't changed. The experience left me glad that I bought their product, which incidentally was not free at the time.

So glad that I make you sick. Will try harder to advance the cause.

Since you were not on my phone call with technician, it's impossible for you to assume I misunderstood anything. Have you actually spoken to their technical support staff?

If you read my other post, you would see and read the documentation and the manufacturer link to it. Take the time to do so before making snarky comments. You should also reread your own quote and notice the operative word "backup". The batteries provide just the power to retain the settings.

Had you taken the time to read and understand the documentation, you'd understand that although you have a c wire and for some reason chose not wire the thermostat with it, you'd realize that your thermostat is being powered as I described and not by your batteries. If you don't believe that, remove them altogether and see that the device still operates consistent with what the manufacturer designed using the low voltage wiring.

Quote from TonMobile :
i can't connect my nest because my house does not have a power c. you can buy the adapter but that is way over my head.

based on all the comments i am still not sure if this unit need a power c or not but so i will hold off for now
Check out this link:
https://sensi.emerson.com/en-us/support/c-wire

" For Sensi™ Smart Thermostat, a common wire (c-wire) is required for heat only systems, cool only and heat pump systems. For Sensi™ Smart Touch Thermostat, all system types require a common wire (c-wire)."

Unless you have a system that does heat or cool ONLY or you have a heat pump, you don't need a c wire. As I said in a different comment, the Sensi uses the electrical current from the wire not being used at the time. If you have a traditional furnace and air conditioning system, this will work right out of the box. Just need a smart phone and their app to install. Their website has useful info that you can review prior to and during installation.

Not sure which part of Kansas you're in, but if you're a Evergy customer, they have free Google Nests several times throughout the year. I think the last one was in November. I had to hook my aunt's up at Thanksgiving. (Overland Park, KS)

Thanks

Keep and eye on this site, though there's no offers currently available.

And it really does depend on your state. Sadly, Kansas doesnt have a lot of energy savings programs as much as the surrounding states.

Edit: Yeah it looks like Missouri has $50 Nests and free ecobees right now.

Quote from Toller :
People like you make me sick. I asked you to document it because I believed you were wrong; not because I feel superior (though clearly I am). Instead of documenting it, you reference some conversation you misunderstood from a tech.

From the Emerson website:
"Two AA batteries (included) provide backup power that can last for months. However, if you have a c-wire, it is recommended that you connect it."

If you don't install a C wire, the batteries run out quickly. Could anything be clearer?
So glad that I make you sick. Will try harder to advance the cause.

Aren't these the type the power company can shut you down if demand usage is high?

You're probably thinking of the new digital meters that they can read and control from HQ (The big thing usually on the outside of a house with a wheel or digital counter). There aren't any thermostats I'm aware of that your utility company could access without your permission

Meh, Sensi Smart isn't that great and it's not even free. Previous deals for Ecobee or Nest were way better. I'd wait for those to come back.

they say it doesn't need a c-wire but my use case shows otherwise. it stopped working on 15 out of 16 furnaces I tried it on

It does. I actually got this on promo for $4 in December. They make a product called fast stat that you don't need to run a c wire and it works.

Anyone remember years ago when some smart thermostat did an update that left millions without heat in the middle of winter? I don't see any good reason to trust some unknown aholes with your safety.
