      OK. I left my home during this weekend but I will try monday and then I will communicate you the result 🙂

      Have a nice weekend.

      Good Morning,

      The sketch :

      /**
       * The MySensors Arduino library handles the wireless radio link and protocol
       * between your home built sensors/actuators and HA controller of choice.
       * The sensors forms a self healing radio network with optional repeaters. Each
       * repeater and gateway builds a routing tables in EEPROM which keeps track of the
       * network topology allowing messages to be routed to nodes.

    • Conversion to mysensors 2.0 for BMP180

      Hi,

      Since yesteday, I has trying to convert a script for a BMP180 mysensors but I have a error.

      The old script in mysensors 1.5 is

       * The MySensors Arduino library handles the wireless radio link and protocol
       * between your home built sensors/actuators and HA controller of choice.
       * The sensors forms a self healing radio network with optional repeaters. Each
       * repeater and gateway builds a routing tables in EEPROM which keeps track of the
       * network topology allowing messages to be routed to nodes.
