    • RE: Office plant monitoring

      Greenhouse

      I want to monitor soil moisture and switch on irrigation valves and pump. Windows open arduino but why not mysensors+domoticz. I can't and not want every morning go to open greenhouse windows. let this make computer 🙂

    • RE: Reporting Battery Level

      Verification successful says codebender. I do not know working this or not. I can't try. Only in home after working day.

    • RE: Domoticz as controller **and** a gateway for MySensor nodes running on a Raspberry Pi 2

      If you sensors working ok than you need to go domoticz hardware-> devices. Marked with green arrow is new node. You need to press to green arrow and....... you see what you want.
      Sorry my english. Maybe you understand. 🙂

    • RE: nRF24L01+PA+LNA MAX power

      Hey.

      If i need change nrf tx power in arduino sketch. This is right ?
      #define MY_RF24_PA_LEVEL RF24_PA_LOW

    • RE: Moisture sensing + relay. Please help with software.

      @gohan said in Moisture sensing + relay. Please help with software.:

      I think you forgot to close a parenthesis in the receive function. If you like a more helping programming interface, you can install visual studio and the extension Visual Micro that are much better than Arduino IDE and help you also visually with parenthesis and auto completion of functions and variables names.

      I use linux. Ubuntu. For linux what software ?

      Line 84 a function-definition is not allowed here before '{' token
      I put these 2 line with include after defines.
