Stupid question... Did you mount the radio? Because I thought I would like to test if it works. (without radio) but that doesn't work.

Mounted a radio and ethernet gateway is working.

I am also not get it to work in Domoticz tried the USB serial and ethernet way.

It's a testing pi. Where i didn't connected the radio. Because it's still in the Nano. Could that be the issue? I guess not.

@BartE

How do you record an IR in Domoticz? Can you explain in detail please? I tried several things bit can't get it working.

@Wackid

I know how to read out the IR signals. And to put it in the sketch manually. But I really like to make use of the record function.
Where and how do I make the node to set it in learn function.

So how can is set this node in learnmode?? V_IR_RECORD in the Serial of Arduino?
How do i store codes in the Eprom. SO i can use them in Domoticz

Thanks... tried to update. But my serial is a Mega 2560.

So it gives an error. Remembers me i found a topic to switch the pins and change them in the sketch.

When i want to update to 1.5. I guess my current readings of Powerpulsmeter and waterpulsmeter are lost?

Is there a way to set those values over to the new version?
