A message from our founder

cosy.green is born out of a simple yet profound realisation. Years ago, I was astounded to find that the thermostats in my rooms couldn't communicate with the central plant to efficiently control the warmth I needed. It was a glaring oversight in a world of endless technological possibilities.


Fast forward a couple of years, and our mission has crystallised. Every year, a staggering 4.2 gigatons of CO2 are released into the atmosphere to heat our living spaces. What's more, a remarkable 80% of residential heating systems remain improperly adjusted, contributing to this environmental crisis.


At cosy.green, we combine the power of smart thermostats and AI to create a revolution in residential heating. Our innovative approach allows off-the-shelf thermostats to communicate with the central plant, ushering in a new era of efficient, eco-friendly heating.
