What others asked before buying

Can I control all my Mysas in the same app?

Yes. Control everything from the one app. Manage baseboard heating, ductless mini-splits, central HVAC, and electric in-floor heating in one place.Set unique schedules for each thermostat, and in the future group them all together for seamless control.

Does it require Wi-Fi?

Yes. Mysa needs a 2.4 GHz WiFi connection to enable remote control, voice commands, smart home integration, and app-based features like energy reports . Without WiFi, the thermostat still regulates temperature using manual controls on the device itself, but you lose all smart functionality. Make sure your WiFi signal reaches the thermostat location before installation

Does Mysa have a microphone or speaker?

No. It's a thermostat, not a listening device. We believe those experiences are best left to a smart home speaker that's likely updated more often than your thermostat.

Does Mysa sell my data?

No. We sell thermostats. That's how we make money. Full stop.

Does the Mysa Smart Thermostat support Matter?

Yes. The Mysa Smart Thermostat (for Central HVAC) is Matter certified. Matter is the universal smart home standard, so you can connect Mysa directly to Apple Home, Amazon Alexa, Google Home, and more for voice control and cross-platform automation — with no extra hub required.

The Mysa Central a/c works well

The Mysa Central a/c works well. It shows information easily and can be figured out by people without having to study the screen. The app shows activity at many different levels, from overall usage to granular showing of temperature in the room.

Sleek design and easy to use

I own all the other Mysa products for mini split and baseboard heating and they work great. I was waiting for central heating products to arrive and now have three installed with ease. Excellent customer support with my C wire adapter wiring.

I'm having a problem with installation

I'm having a problem with installation. The **** terminal (for the red wire) coming out of the c-wire adaptor seems to have failed. The **** is not gripping or holding the red wire. While I hold it in place, the thermostat is powered, but the connection is very intermittent when I let go of the wire. This is the 4th unit I have installed, and the first time I have had this problem. Can I return it for a replacement.

Controlling baseboard heaters using low voltage relay

Controlling baseboard heaters using low voltage relay. I didn't know if I could do this with an existing relay setup. By adding the controller and the C-wire power adapter it works perfectly.

One of the things I like is the communication your firm promotes

One of the things I like is the communication your firm promotes. You cannot find that with many suppliers.

I now have two units and will get two more soon. We have two homes and I like the ability to manage each one separately.

Nest (Google) failed me.

Thanks, Mysa.

Superb customer support that gives me great confidence in the company

I was installing this thermostat to replace an existing two wire thermostat that ran a relay switch to a group of baseboards. It is not a normal install and the support from Mysa was nothing short of superb. They sent complete descriptions and diagrams on how to hook up, all within a few hours of my inquiry. Hard to find such good service these days.

Great smart thermostat replacement

Replaced a nest thermostat that was no longer supported and a mercury thermostat in the garage. Went with Mysa again as I have one at our cabin. Great product

Apartment HVAC Game Changer

The thermostat in my apartment when I moved in was a single function unit that never really seemed to know what temperature it actually was but the Mysa one I installed can keep an accurate range (with humidity which is so nice for my allergies) with heating and cooling boundaries. It looks better and works better.

There is one thing that could be better - knowing how common jumper wires are and the variability of low voltage terminals it would have made installation so much faster and easier if I didn’t have to go to 3 different hardware stores to try to find a wire that worked to jump the necessary terminals. Aside from that it’s great and I’m very pleased.

HVAC thermostat not as smart as the Baseboard thermostat

HVAC thermostat doesn’t have the Early Start feature . It also doesn’t call HEAT when temp goes down 1 degree. Room temp sits 1 degree below set temp for a long period of time before calling for HEAT and there are times when I have to adjust the thermostat 2 degrees above room temp just to get the HEAT on and back up to set temp. It also doesn’t allow switching between FAN AUTO and FAN ON with completely reconfiguring the thermostat.

Software programming needs a bit of work to get it up to Smart Thermostat standards.

Doesn't work as advertised. Does not connect to Amazon Alexa. They said they're "still working on it" which is lame. And misrepresentation.

Works great

The product works great and looks good.
The app is easy to use and I like that the dashboard show both the setpoint and current room temp, not just the setpoint like some products.
Scheduling is easy.
