Hi,
I live in Belgium and soon Fluvius, the company responsible for electricity infrastucture, will install a digital meter with P1 port. Maak je digitale meter slim | Fluvius
Yes, I was able to manage. I use ESPHome, so ESPHome has a P1 integration. You only have to use an ESP module and connect the output (transmit line) of the Smart Meter to an input of the ESP. The ESP is even powered by the Digital Meter.
The ESP with ESPHome delivers all entities. No need to install a HA integration like P1 Monitor or DSMR Slimme Meter.
These are the most important entries in my ESPHome configuration:
uart:
id: uart_bus
rx_pin: 3
baud_rate: 115200
The rx_pin off course depends of your hardware setup
i am also very interested in the possibility of obtaining real-time energy information via the P1
of Fluvius. (i am living in Brussels and energy cost is VERY HIGH))
can you explain me how to plug the sonoff relay on Aliexpress to p1 ? (which cable)
How to integrate into HA '(esphome , dsmr ?? can you explain me please)
there is also a solution more expensive : https://www.connectix.nl/belgische-slimme-meter-uitlezen-met-home-assistant/
but i prefer your solution (cheaper)
I live in The Netherlands and use over 2 years the more expensive connectix solution.
The integration in to HA is easy, and it works like a charm… without any problems.
Let say: this device is (almost) plug and play, only a few settings… and that’s it.
My post from 1 feb. explains how to connect.
The module I bought is a generic ESP module. The module is powered from the digital meter.
You only need the module, a 6-wire flat cable and the RJ12 connector to plug into the digital meter.
Sounds very easy but to be honest you must be familiar with electronics and/or be handy to ‘create’ this module. If it’s not your cup of thea, better spend some money and buy something familiar as mentioned in this thread.
If you already use ESPHome you should be familiar how to ‘program’ the ESP module.
Do you already have curves (via apexcharts or other graphical cards) based on the entities produced by the interface that I could install in my home assistant, such as the ‘total daily/monthly’ cost of electricity’, etc.)
