Hi Richard,
I'd like to utilize the water level sensor portion of your project. I am new to the home automation/arduino world so I figured I would start small lol. I put together the moteino transceiver, got the eTape, set up an account with emonCMS and downloaded the emonCMS API to communicate with HomeAssistant on the rasPi. The glaring question I have at this point is do I need an emonPI to communicate the data from the eTape to emonCMS ? Or is there a Lib/variable allocation in arduino IDE that I missed when I was learning that would allow for direct communication to emonCMS.org ?

Fun project/Enjoying the process!
Jamie
