Smart Meter (Steiermark - Graz)

Intro During this years summer vacation I invested some time into reading out energy consumption from my electric smart meter (Sagemcom T210-D-r) and the heat smart meter (Kamstrup Multical 403). I assume that this might be of interest for other people which do get their electicity from Energie Steiermark and do have a Sagemcom T210-D-r smart meter installed do have a central heat supply from Energie Steiermark and do have a Kamstrup Multical 403 smart meter installed Hardware Setup I am reading both smart meters via a Raspberry Pi device using the interfaces as described on the github repo.

UniFi Home Network

In 2020 I decided to switch for the core network backbone of my home to switch to Unifi. Hardware USG-3P US-16-150W 2x UAP-AC-Pro UAP-AC-LR USG Dnsmasq (DHCP and DNS) USG is actually running EdgeRouter OS. See Documentation for how to use cli commands together with the unifi controller. mca-ctrl -t dump-cfg > config.gateway.json Main reason for switching to configuration on file basis was that I wanted to use UGS as DHCP and DNS service provider for my network.
