    Hello,

    after 2 years i started again with mysensors, specially for my sons aquarium. i have a temp-sketch working and a button-sketch-with red and green leds working (a reed contact float for water level, and green and red LED for indicate the level near the aquarium, besides a switch signal to the controller (domoticz)). i want to combine both sketches and i came up with this sketch. compiling works fine, but before im broke up my 2 working sketches, will this sketch work? or am i missing something or did i make some mistakes?

     * 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.
