Hi, In one of your posts you mentioned, "In my home environment I have modbus device and hf2211 modbus->wifi bridge that I'm polling ever 1 second from node-red". I have the HF2211 which I have set up and via modbuspoll I can read the various registers on an SDM630 electricity meter. I am brand new to Node-Red but really want to read the registers from Node-Red and I wondered if you could share you flows in some way so I can see how you are connecting with and reading the HF2211. Sorry it's not to do with Hubitat directly bu this is the only place I've found where somebody has referred to the HF2211 and Nod-Red together.... thanks Mike
