@SteveO1234 said: Thanks for the encouragement and help! So it seems as I need to create this message handler function that is referenced in the gw.begin().. And from that point any incoming messages are routed through the function? yup, So, you then have to manage a variable Vera-side that will then get polled from time to time by your Arduino. that request is bounced back as a message, that you handle as you noted above. Look at this example to see how you can manage the change of a stored variable in the Vera device... you merely need to update the stored variable in a change of state, and poll as frequently as you want to update. You can also send Vera html messages that in-turn would generate a message to a node in MySensors space. have fun!
