Linky integration in standard mode with Home Assistant and Tasmota

Sat, 18 Jan 2025 00:00:00 +0000

Linky integration in standard mode with Home Assistant and Tasmota.

In this post, we’ll go through the steps to get energy data from a Linky in standard mode right into Home Assistant through MQTT using Tasmota running on a ESP32 with a Wemos Teleinfo Hat.

1 - Tasmota (Linky side)

On the linky side, the hardware will be :
- Module WiFi Mini NodeMCU ESP32 D1
- WeMos Teleinfo ESP8266/ESP32/S2/C3/S3 Shield

Get Tasmota files :

git clone https://github.com/arendst/Tasmota.git

Go to the Tasmota folder

cd Tasmota

Before compiling, let’s enable the support of Teleinfo

vim tasmota/my_user_config.h

And uncomment the following line

#define USE_TELEINFO // Add support for Teleinfo via serial RX interface (+5k2 code, +168 RAM + SmartMeter LinkedList Values RAM)

Create a venv environment and source it :

python3 -m venv ./venv
source venv/bin/activate

Install plateformio

pip install platformio

Then compile and upload :

platformio run -e tasmota32 --target upload --upload-port /dev/ttyUSB0

Then finish the Tasmota configuration as usual :

Connect to the Tasmota Wifi
Go to the 192.168.4.1 IP address
Setup your Wifi

Then go to Configuration -> Other and set as template the following parameters (don’t forget to tick “Activate”)

{"NAME":"Wemos Teleinfo","GPIO":[1,1,1,1,1,1,1,1,1,1,1,1,1,1,1376,1,1,640,608,5632,1,1,0,1,0,0,0,1,1,1,1,1,1,1,1,1],"FLAG":0,"BASE":1}

Then the ESP32 will reboot and you should have something like the screenshot below

Finally, let’s configure the Linky mode to standard

You should have the following feedback

15:02:17.014 CMD: EnergyConfig standard
15:02:17.017 TIC: 'standard' mode
15:02:17.017 TIC: RX on GPIO23, baudrate 9600
15:02:17.019 RSL: RESULT = {"EnergyConfig":"Done"}

Then I configure the MQTT parameters to push data to the MQTT broker

2 - Home Assistant

2.1 - Simple sensors

Integration in Home Assistant is easy.

Here is an example :

type: entities
entities:
 - entity: sensor.tasmota_energy_current
 - entity: sensor.tasmota_energy_voltage
 - entity: sensor.tasmota_energy_power
 - entity: sensor.tasmota_energy_today
 - entity: sensor.tasmota_energy_yesterday

With the following result :

2.2 - Energy dashboard

In order to be able to track cost, we’ll create a template doing a copy of indexes and register them with the right properties (device_class, unit..).

In our configuration we’ll have :

template: !include template.yaml

And in template.yaml we’ll have :

sensor:
 - name: "heure_creuses"
 state: "{{ states('sensor.tasmota_tic_easf01') }}"
 unit_of_measurement: kWh
 device_class: energy
 state_class: total_increasing
 - name: "heure_pleines"
 state: "{{ states('sensor.tasmota_tic_easf02') }}"
 unit_of_measurement: kWh
 device_class: energy
 state_class: total_increasing

Then you should be able to parameter the energy inputs as follow :

Then you’ll have data displayed.

You’re done : Linky integration in standard mode with Home Assistant and Tasmota.

Atlantic heat pump integration in home assistant with BSB-LAN

Sun, 05 Jan 2025 00:00:00 +0000

In order to get our Atlantic heat pump integration in home assistant, we’ll need :
- BSB-LAN running on an ESP32
- MQTT broker up and running on Home Assistant
- Configure BSB-LAN to push data and Home assistant to diplay them.

Thanks to this configuration, you’ll be able to monitor the heat pump data such as compressor activity and sensors. We will be able to control the heat pump using the climate control module of Home Assistant to adjust temperature setpoints.

Hardware : Atlantic heat pump and ESP32.

The first step the hardware part using an ESP32 with a BSB-LAN hat.

You will see on the picture below :
- The ESP32 and the BSB-LAN hat mounted on the door
- The wiring on the X86 port of the Atlantic Alfea Extensa Duo heat pump
- A 230V to USB power supply

Software : BSB-LAN and Home Assistant

BSB LAN on ESP32

We’ll use a BSB-LAN board with an ESP32. Following the official documentation. I recommend to follow strictly the documentation in order to get it up and running.

One BSB-LAN up and running, we’ll configure it to send data to Home Assistant MQTT broker.

Home Assistant on the server

On the Home Assistant side, you should :
- Install the MQTT broker add-on
- Configure the MQTT broker
- Check the configuration using MQTT explorer.

Once the server is up and running, we can see that BSB-LAN is pushing data to the MQTT broker using MQTT explorer :

And then you can configure a nice dashboard such as the following one.

For this dashboard, here is my configuration :

Configuration.yaml

mqtt: !include mqtt.yaml

mqtt.yaml

climate: !include mqtt_climate.yaml
sensor: !include mqtt_sensor.yaml
number: !include mqtt_number.yaml
binary_sensor: !include mqtt_binary_sensor.yaml

Update the RFLink gateway using CLI on your Linux server

Sat, 27 Jan 2024 00:00:00 +0000

Update the RFLink gateway using CLI on your Linux server. We’ll see how to update a RFLink gateway running on an Arduino Mega without having to disconnect it from your Linux server (Home Assistant or Domoticz).

The RFLink Gateway is an open-source platform that acts as a bridge between 433MHz sensors and other smart home systems, such as Home Assistant or Domoticz.

By using RFLink, users can integrate a wide variety of 433MHz sensors with their home automation ecosystem, enabling seamless control and monitoring of devices like door/window sensors, temperature sensors, and motion detectors. This gateway simplifies the setup process, providing compatibility with many different sensor brands and protocols. RFLink enhances the versatility and interoperability of 433MHz-based devices, contributing to more efficient and connected smart home environments.

Software on the Linux server to update RFLink Gateway

Install Avrdude :

sudo apt-get install avrdude
