What's New in Mysa

4.16.1

June 2, 2026

General improvements and bug fixes.

User reviews

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.

Becoming useless

Two of my six thermostats keep turning on, even though I have all of them set to “hold until you change it.” I turn them both off and they continue to turn back on. NO, no one is touching them, I live alone. This is clearly an app and/or hardware glitch and it needs to be fixed!! I do not need my heat running simultaneously with my AC, my utility bills are expensive enough!!!

Junk

Like everyone in recent reviews is saying. No longer works and tried pairing many times.

Now it’s just trash

Pleased until the latest update

Thermostat is not responding and tech-support started with an AI bot.

Amélioré ne veut pas dire meilleur

La version précédente était meilleur. Pourquoi avoir diminué la grandeur des graphique de
Température pour mettre des bordure inutile?

L’application réagit beaucoup trop lentement. Quand le soleil se couche, la température diminue et l’application n’anticipe rien. Elle met plusieurs minutes avant de réaugmenter.

Pourquoi ne pas mettre un mode pour le ac split qui mettrait la thermopompe en mode ventilation lorsque le soleil plombe au lieu de simplement fermer le chauffage?
