Get started

Turn your heating and cooling on and off, and change temperatures and schedules, from anywhere — with no Airzone cloud subscription. You need a small €15 box plugged in at home and about ten minutes.

1. Buy the box

   An M5Stack Atom Lite, about €15: buy it on Amazon.

   You also need a USB-C cable and a USB phone charger. Most homes already have them.

2. Put Warmhole on it

   On a computer with Chrome or Edge, open the install page, plug in the box and press Install. It takes a minute and you only do it once.

3. Plug it in at home

   Use any USB charger, somewhere your home Wi-Fi reaches. The box stays plugged in from now on.

4. Set it up from your phone

   Join the Wi-Fi called Warmhole-Setup. A page opens: enter your home Wi-Fi, your Airzone email and password (the ones of the official app), and choose a password for Warmhole.

   Choose a Warmhole password that is different from your Airzone password (and from your email password). It is the only one that travels over the internet: you type it every time you sign in to this site. Your Airzone password never leaves the box.

5. Sign in

   Come back to this site, sign in with your Airzone email and your Warmhole password, and add it to your phone's Home Screen. Done.

Good to know

• It's free. No subscription, no fees. You can support the project if you like, but you don't have to.
• Your Airzone password stays in the box, in your home. This site never keeps it.
• Your system must already work with the official Airzone app. To change schedules, your Airzone account must be an administrator of the system.
• If the box is unplugged, Warmhole can't reach your system. The official app keeps working as usual.
• It's a free beta made by an independent person, not by Airzone. It may have bugs, and it may stop working if Airzone changes its service.
