Great device - rubbish instructions.
Excellent quality product. Very well made. Lost 1 star due to the instructions which are very poor with limited information and many web links broken. You might think you can configure it via an onboard routine but in reality you have to plug it in to an existing PC via an ethernet lead then set the ip address of that ethernet port to the one in the documentation and then you change the ip address to one suitable for your home network. Easy when you work it out but you shouldn't have to work it out - the instructions should be clear! Once setup it has worked faultlessly.

Works perfectly
Works great and does exactly what was expected. Software they provide really makes configuration easy. I just wish it was smaller.

Verlässlich
Kommuniziere darüber mit der Steuerung von unserer Warmwasserbereitung mit Wärmepumpe und PV Einspeisung. Die Daten können super mitgelesen werden, wen man will kann man auch in die Steuerung eingreifen.

DNP works.
Worked with DNP TCP and UDP. It also includes an AC wall power supply, and M-M serial cable. Easy web interface setup, and status information to help with troubleshooting. The online serial interface would be nice if it could receive ascii, but this is a minor want.
