### What you need
* ESPHome compatible microcontroller (e.g. ESP8266, ESP32, ESP32-S2, ESP32-C3, ...)
* ESPHome compatible microcontroller (e.g. ESP32, ESP32-S2, ESP32-C3, ...)
* ADUM1201 Dual Channel Digital Magnetic Isolator
(to convert 5V UART signal from the heatpump to 3.3V UART signal of the ESP controller)
* CN-CNT cable/connectors to Heatpump/CZ-TAW1 (see [Heishamon](https://github.com/Egyras/HeishaMon) github site for more information)
* CN-CNT cable/connectors to Heatpump/CZ-TAW1 (see [Heishamon](https://github.com/heishamon/HeishaMon) github site for more information)
* For example: [S05B-XASK-1 JST Connector](https://a.aliexpress.com/_EvkmGVo)
* For example: [XAP-05V-1 5Pin Cable with Female to Female Connector](https://a.aliexpress.com/_ExPT82E)
> [!IMPORTANT]
> The support for ESP8266 and the arduino framework is deprecated for this component.
> Since v0.0.8 this component uses threads to process the UART communication.
> But if you still want to use an ESP8266 controller or the arduino framework,
> please use the branch "heatpump/arduino".

## Custom Entities (For Advanced Users)
If you review the [ProtocolByteDecrypt.md](https://github.com/Egyras/HeishaMon/blob/master/ProtocolByteDecrypt.md) file you will find also some TOPs and SETs which are not implemented yet in heishamon.
If you review the [ProtocolByteDecrypt.md](https://github.com/heishamon/HeishaMon/blob/main/ProtocolByteDecrypt.md) file you will find also some TOPs and SETs which are not implemented yet in heishamon.
They are usually marked as TOP (without a number).
The nice part of ESPHome is that it is so highly customizeable.
So if you want some additional TOP or SET entities you can easily create your own.
