Lumos smart switches replace the switch panels on your wall. The free meshams app for Android and iPhone is where you name them, set the fan speed, time them, and share them with your family. Every screen below is from the app as it is today.
Each key on a Lumos panel shows up in the app under the name you give it: Alley Light, Chandelier, Geyser. Panels are grouped by room, so you can see the whole house at a glance and switch anything from wherever you are.

A Lumos fan key is a smart fan regulator as well as a switch. Tap it in the app and slide between speeds 1, 2, 3 and 4, or switch the fan off. The same speeds are on the panel, so nobody needs the app to use the fan.

Give an action a name, pick a key and a time, and choose whether it should turn on or off. The app does it at that time, whether or not your phone is with you, and keeps a list of what ran.
Choose Multi and the key switches on at the time you set, then off again after the number of minutes you choose: a geyser that runs for 20 minutes before your shower, or a phone charger that stops overnight.


With a meshams sensor in the room, an automation switches a Lumos key when the temperature or humidity crosses a level you set: the fan comes on above 30°C and goes off again when the room cools, or an exhaust runs when the bathroom gets humid. Automations sit next to your timed actions in the Actions tab, and you can pause any of them.
The home's owner creates an invite in the app and gets a 6-character code. Anyone in the family enters it under Join a home in their own meshams app, and the home, its rooms and its switches appear on their phone.

Each place is a unit in the app with its own rooms and devices. Add your home, your office or your parents' flat, and switch between them from My Units. Useful when you look after a home you don't live in.

Link Alexa and Google Home from your profile and every key can be switched by voice. Claude goes further: it can set fan speeds, switch a whole room and create timed actions for you.
