Kelva
Know every room is warm and dry.
Kelva makes small, quiet sensors that watch the temperature and humidity in every room of a home, and tell you early when it is turning damp or cold, long before mould gets a hold.
The Cube
One small cube for each room. It measures the air every few minutes and sends its readings over the mobile network by itself, so there is no Wi-Fi to set up, no hub and no app to pair. Put it on a shelf, choose the room, and leave it.
Everything it sees turns into plain answers on your dashboard: which rooms are fine, which need a look, and what to do about it.
Temperature and humidity
Measured every five minutes, in every room you put one.
Mobile network, built in
Connects over LTE-M by itself. Nothing to plug into your router.
Years on batteries
Sleeps between readings and sends them in small batches.
For your home
See at a glance that every room is comfortable, and get a nudge when the bathroom stays damp or a bedroom runs cold overnight.
For landlords
Every property and room in one place, the rooms that need attention first, and a clear record of conditions over time.
In development. The first Cubes are being tested now.
