# Froeling Lambdatronic Modbus
|
||
Home Assistant integration for Fröling Lambdatronic heating systems via Modbus (currently supports Modbus TCP only - maybe ).
|
||
|
||
## ⚠️ Disclaimer ⚠️
|
||
> **This integration is experimental and has not been tested over long periods.**
|
||
> It may contain missing or incorrect sensor data.
|
||
> Feel free to open an [issue](https://github.com/GyroGearl00se/ha_froeling_lambdatronic_modbus/issues) or contribute via a [pull request](https://github.com/GyroGearl00se/ha_froeling_lambdatronic_modbus/pulls).

|
||
## 🚀 Features
|
||
With this integration, you can:
|
||
- Read real-time sensor data from your Fröling heating system.
|
||
- Monitor boiler performance and operational parameters.
|
||
- Configure heating system settings directly from Home Assistant.
|
||

|
||
|
||
## 💻 Requirements
|
||
To communicate with the heating system, you need a Modbus-to-TCP device.
|
||
This integration has been tested with the **Waveshare RS232/RS485 to Ethernet Converter**, but other Serial-to-Ethernet adapters should work.
|
||
|
||
### 🔧 Enabling Modbus RTU on the Boiler
|
||
To enable Modbus RTU on your Fröling boiler:
|
||
|
||
1. Navigate to **Boiler Settings**.
|
||
2. Click the user icon and enter code `-7`.
|
||
3. Adjust the following settings:
|
||
- **Settings > General Settings > MODBUS Settings > Modbus Protokoll RTU** → `Set to 1`
|
||
- **Settings > General Settings > MODBUS Settings > Use Modbus Protokoll 2014** → `Yes`
|
||
- **Settings > General Settings > MODBUS Settings > Use COM2 as MODBUS Interface** → `Yes`

## 🛠️ Hardware Setup
|
||
I used a [Waveshare RS232/RS485 to Ethernet Converter](https://www.waveshare.com/rs232-485-to-eth.htm) and connected **RS232 to COM2** on the boiler.
|
||
|
||
|
||
|
||
Other Serial-to-Ethernet converters should work as well.
