5.0 out of 5 stars Works Amazing!

2026-01-26    -Bob G.

One of the best thermostat products I have ever purchased. I have several of them which I use to control Cadet 240v electric heaters in my garage and cabin. They are very well designed, easy to install and set up and have been very reliable. I appreciate the ability to monitor not only the heating usage but also the power drawn. They are very easy to integrate into Home Assistant, HomeKit, or just standalone with the Mysa app.

5.0 out of 5 stars Well designed, easy to install

Very well designed thermostat, with a really slick and smooth installation.Of course, before installing it, I had to take a look inside. It's really well designed, and also contains a lux sensor and a humidity sensor, which I did not realize when buying (but are a nice plus). An ESP32 is used for networking, so it should be pretty easy to convert to ESPHome if/when this company goes bankrupt. The device also works great with HomeAssistant for local-only control. I was notified the device existed, I typed in the code from the manual, and now I can access it & automate it.On the other hand, the app, while functional, has a couple dark patterns. You are unable to use the device without an account, which is entirely unnecessary since the device works just fine without the internet. It also subscribes you automatically to their pointless mailing lists, and doesn't give you an option to opt-out on signup.

Worth The Price

The thermostat itself is a high quality build and has an app that is easy to use and doesn't require any subscription at all. It was simple to understand the install and an added bonus that it comes from a Canadian company.

I really want to like this product but it stopped working after approximately 10months and no longer functions.At first it would power off and boot right back up, now it doesn’t work at all. I constantly get notifications that is offline and do not see a support function on this product.@Mysa if you are reading this please contact me, I need some support

4.0 out of 5 stars Easy to set up - very picky on network settings for Home Kit integration

Just installed this today, so far it works fine. Takes a while to heat up my floor but that may just be an issue with the heater mesh install which was done before I bought the house I'm in. Previous thermostat was a suntouch from 2004 that was crumbling apart and had a very bad coil whine.Install was easy pretty easy. I like that there's a plate to install and the brains are on a removable faceplate. It made the install very easy. Before you install this (but right after you remove your current thermostat if you are replacing it) measure the resistance of your thermistor/floor temp probe, you'll want to validate the temp probe resistance setting after you add the thermostat to the app. The instructions do not point this out.Adding to homekit was a nightmare. Definitely set up the thermostat from the app using the homekit method. But you definitely need to have your wifi network properly configured. With the way most smart home devices work you can rarely blame the manufacturer unless if they're using a terrible bluetooth radio and pairing with a hub or appletv (I'm looking at you 3rd gen august smart locks).Firstly you should be using a separate network for IoT devices, for security and compatibility purposes. You can google why you should have your IoT devices segmented away from you main network. There are plenty of videos and articles that will explain this in leighman's terms, and there may be videos for your specific (or similar) router on how to set this up mostly.These are the settings that I needed to have for my IoT network to get this to connect properly via homekit. I am using a Ubiquiti Unifi based network with a UDM pro and 3 Access Points.- Turn off IGMP snooping- Turn on Multicast DNS- Only have the 2.4 GHz band turned on for the IoT wifi network- Both multicast management options unchecked- Uncheck minimum data rate control- Have the 2.4GHz density slider all the way over to 1Mbps- Security protocol set to WPA2 (another reason to have a separate IoT network)This is using an ESP32 at least from what you can see on the back of the faceplate as the chip is there. Overall I'm confident in this device and it looks great in my master bathroom.All things said and done, it works great so far! I will update this review after a while or if I run into major issues.
