Dutch Smart Meter over WiFi adapter (DSMR over WiFi)

My smart meter is installed in the cellar where no patch cables are available. I could use a raspberry pi only for connecting the smart meter but I would need a rs232 p1 usb cable too. I thought this could be easier.

Therefor I made a wifi box to connect my P1 port and use telnet to connect to Home Assistant (with using DSMR-Reader as a proxy (mqqt). More about my project can be fount on my website (in Dutch).

Very interesting. Will work with homeassistant installed on Linux. But how will that do with homeassistant “appliance”?

I tried to use it with the dsmr integration in HA and tried to connect it by ip but didn’t get it to work. Now I use dsmr-reader as a proxy wich gives me more details than HA alone. The mqqt connection in dsmr-reader publishes the updates to HA which works perfect now for more than a year.

Hey, I just used a likewise function that has been working perfectly, but after the new update of Home Assistant my DSMR is not reading out anymore. I already checked with putty that it is still spitting out data but DSMR cannot read it. @Roel_van_Wanrooy is there something broken for you 2?

Hi Mart,

Everything works perfect after the update.
