# Home Assistant Tesy integration

This unofficial Tesy integration allows you to control smart wifi devices based on external esp32 wifi module (black pcb).
It won't work if you have older device based on Atheros AR9331 chipset since the local API is different. In this case the module could be replaced with esp32 replacement module as they are compatible with most of Tesy water heaters, even if not comming with WiFi from the factory.

Tested with:

- [Tesy Modeco Cloud GCV 150 47 24D C22 ECW](https://tesy.com/products/electric-water-heaters/modeco-series/modeco-cloud/?product=gcv-1504724d-c22-ecw)
- BilightSmart
- BelliSlimo
- [Tesy BelliSlimo Cloud GCR 80 27 22 E31 ECW](https://tesy.com/products/electric-water-heaters/bellislimo-series/bellislimo-cloud/?product=gcr-80-27-22-e31-ecw)

## Highlights

This integration allows you to change modes of the water heater as well as controlling the temperature setpoint in manual mode (defined as Performance in HA).

Energy counter is also working. It uses long term counter from the device that counts the seconds the heater was on. In order for this to work properly you need to enter your heater power rating in the setup dialog. This information could be found on the device's label. For double tank devices this is read from the device and leaving it as zero is recommended.

The integration provides two energy sensors: `Energy Consumed` tracks total lifetime usage. `Energy Consumed (Resettable)` uses the device's built-in resettable counter - reset it from the Tesy app to track usage over a specific period, like a trip odometer.

This integration exposes boost mode of the heaters as a switch. It can be switched on and off, but in order to work the heater should on.

Child lock switch prevents accidental changes (if supported by the device).

Temperature setpoint is only used in manual (Performance) mode. In any other modes it is ignored. If setpoint is manually changed operation mode will jump to performance in case the heater is powered on.

## Installation

### Via HACS

[![Open your Home Assistant instance and open a repository inside the Home Assistant Community Store.](https://my.home-assistant.io/badges/hacs_repository.svg)](https://my.home-assistant.io/redirect/hacs_repository/?owner=krasnoukhov&repository=homeassistant-tesy&category=Integration)

* Search for "Tesy" on HACS tab in Home Assistant
* Click on three dots and use the "Download" option
* Follow the steps
* Restart Home Assistant

### Manual Installation (not recommended)

* Copy the entire `custom_components/tesy/` directory to your server's `<config>/custom_components` directory
* Restart Home Assistant

## API Details

The device exposes a local HTTP API at `http://{device_ip}/api`. You can retrieve all device parameters in a single request:

```
http://{device_ip}/api?name=_all
```

This returns a JSON object with all fields listed in the table above.
