Hi all,
I just read something about the possibility, in Italy, to read values directly from the power meter using the “Chain 2” communication protocol.
For what I can see, it is still experimental, but some companies are already selling a domestic device able to talk to a smartphone app about energy consumption, real-time energy draw, alerting when the drawn power exceeds the maximum contractualized power.
Any italian here tried to use those new devices and integrate with Home Assistant?
The company “MAC Srl” is publishing the data sheets of two products, a plug device and a DIN rail device, that seem interesting:
They support Wi-Fi and BLE, MQTT, Websocket, REST API…
You need to be an “authenticated” company/entity to have access to the Chain 2 specs and be able to read the values from the Open Meter counter.
There is an Italian company that sells a device able to do so and that can be integrated into HA:
Is anybody in Italy using chain2 protocol for the energy dashboard?
I get it and it’s really working good with the app Afa, but i need help to use the data from chain2 protocol into the energy dashboard…
I already installed it and it’s working good. The only thing i still don’t understand is what these sensors do and what is their meaning:
- name: Pot Att Prel Quart Media
device_class: power
unit_of_measurement: W
state_class: measurement
data_type: uint16
address: 9
- name: Pot Att Imm Quart Media
device_class: power
unit_of_measurement: W
state_class: measurement
data_type: uint16
address: 19
There is an integration available from HACS.
I have tri-phase system with solar panels and batteries. I tried using it and it has an issue, when the batteries are charging, Alfa looses the connection with the power meter (contatore). I assume there is an interference on the eletrical network when batteries are using energy produced by solar panels. Just an info for those who plan to use it.
