Hi
I'd like a couple of reed switches on my doors (door sensors). Since I already have the RF radio in the emonpi, it would be nice to communicate via that. How can I do this?
* Is there a shield for arduino to do this?
* Can the emonTH accept and transmit extra inputs?
Re: Building devices to use same RF as emonTH
There is a digital input (DIG2) with a pull-down resistor available on the emonTH's terminal block, which could be used for a reed switch. You would need to add the appropriate statements to the sketch to read the switch, debounce it and send the value onwards in the radio packet.
