Loxberry Plugin: P1 Decrypter

Plugin to decrypt Smart Meter output over P1 customer interface and send it over UDP, MQTT and/or to a serial port.

German readme: https://github.com/metrophos/LoxBerry-Plugin-P1-Decrypter/blob/main/README-german.md

Precondition

• Smart Meter that has a P1 interface (Tested with Smart Meter: Sagemcom T210-D-r in Austria)
• FTDI USB cable to connect to the Smart Meter
  • One possibly option: https://www.aliexpress.com/item/32945225256.html (Option/Color: Sagemcom XS210 -> Sagemcom T210-D-r)
• Your energy provider has to activate your customer interface and provide the encryption key "Global Unicast Encryption Key (GUEK)"

Value mapping

If you don't need all informations of your smart meter you can use the value mapping. Format is:

'label','regex'
'label','regex'
'label','regex'
...

Disable value mapping by enable raw switch.

Example

To get 1-0:1.8.0:001234567\n from raw output 1-0:1.8.0(001234567*Wh)use value mapping like this: '1-0:1.8.0','(?<=1-0:1.8.0\().*?(?=\*Wh)'

Miniserver configuration

• Virtual UPD input:
  • IP address: Your Loxberry IP
  • UPD Port: 54321 (or what you use configured over the plugin configuration)
• Virtual UPD input command:
  • command recognition (If you use the value mapping example above): \i1-0:1.8.0:\i\v

To check incoming messages from Loxberry to Miniserver use Loxone UPD monitor

Example to use by energy monitor

• In this example all values are in Watt. They have to be divide AI1/1000
• In this example 1-0:1.7.0 and 1-0:2.7.0 must be connected by this formula (I1-I2)/1000
