General Improvements and Bug Fixes

User reviews

Lots of bugs

The hardware is good, but the app needs serious attention. We regularly experience disconnects that require us to reconnect the system. The Home, Away, and Vacation triggers are unreliable. The Usage Tracking feature also doesn’t report any usage at all. We brought this issue to the support team and were told it’s a known problem, but it’s frustrating to see known bugs remain unresolved.

Scheduling is another major issue. When we set schedules for each thermostat, some of them will randomly disappear, meaning we have to go back and recreate them.

We use Mysa with our mini-split systems at an Airbnb, and when everything stays connected, the hardware works pretty well. Unfortunately, the app’s reliability makes it difficult to trust the system, especially when we’re relying on it to manage a property remotely. We also find the controls somewhat confusing for guests.

Mysa developers, please take these issues seriously and fix the reliability problems. The hardware is capable, but the app is holding the whole system back. A smart thermostat is only as smart as the software controlling it.

Inconsistent readings

Android app correctly shows the current temperature in all 5 rooms but iPad app only shows 1 of 5. Force closing brought up another one but still only 2 of 5. All 5 set points show up correctly.

Has bugs

When it works it’s great! You can control it from anywhere. I have had several issues with mine and it keeps going offline. Reconnect it is a pain and does not always connect Have had to report and completely delete app several times.

No longer works with Google Home

Main reason I bought was these work, or used to work, with google home. Somewhere recently it stopped worked and just shows as offline in Google

Not good

The app is always having problems connecting to the actual product it. In the middle of summer someone decided to turn it on manually and when I went to the app it would not turn off or go down. The actual product will also not manually turn off or go down which can result in very bad problems.
