    James, we’ve been playing with hardware designed for this for quite some time (as a subfolder in our SensorModbusMaster repo), and just recently spun our commits/designs into it’s own Mayfly-Modbus-Wing repo. Have you seen this?

    Our solder-your own DIY version is described here: https://github.com/EnviroDIY/Mayfly-Modbus-Wing/tree/master/Modbus-Mayfly_WingShield

    We have some work to do on improving documentation, but hopefully this will all be helpful.
