I am in charge of a temperature monitoring and controlling project in a new building with 7 floors and 14 rooms by floor.
I installed last week thermostats devices in each rooms permitting to send user set point temperature to a master device (2 by floors located in corridors) which are driven the underfloor heating.
The system works fine, but sometimes, I have some communications problems between thermostat and its master device due to the fact that the building is a bit too long for a good communication.
All communications between devices is done by RF 868MHz.
I am looking for ideas helping me to improve the RF communications between devices
