The crossroads of tradition and technology
In my home, I have a geothermal system and set of devices for very detailed power monitoring. The cheapest way I've found of monitoring all of that is by using a Barionet 50 from Barix. It includes a host of useful features but the two most important to me is the ability to plug in up to 50 1-wire temperature sensors and that is acts as an RS485 gateway. The 1-wire temperature sensors are used to check the temperature of the geothermal loops and the RS485 gateway let's me interact with my branch circuit monitor via Modbus.
