There are 3 parts to this project, first the design of the circuit, secondly the code for the ESP8266 microcontroller firmware with telnet and MQTT support, and lastly an example configuration for Home Assistant to monitor the data and issue direct commands via a MQTT broker.

If MQTT is not used set the MQTT_HOST to `NULL`.
These incoming MQTT topics are also handled:
| topic | ID in my_config.h | Payload | Description |
| ------------------- | ------------------------- | ---------------------- | ---------------------------------------- |
| thermostat_cmd_temp | TOPIC_THERMOSTAT_CMD_TEMP | temperature as a float | sets the thermostat current setpoint |
| thermostat_cmd_mode | TOPIC_THERMOSTAT_CMD_MODE | auto, day, night | sets the thermostat mode |
| wwactivated | TOPIC_BOILER_WWACTIVATED | 0 or 1 | turns boiler warm water on/off (not tap) |
If MQTT is not used use 'set mqtt_host' to remove it.
Some home automation systems such as Domoticz and OpenHab have special formats for their MQTT messages so I would advise to use [node-red](https://nodered.org/) as a parser like in [this example](https://www.domoticz.com/forum/download/file.php?id=18977&sid=67d048f1b4c8833822175eac6b55ecff).

The ESP8266 will start in Access Point (AP) mode. Connect via WiFi to the SSID **EMS-ESP** and telnet to **192.168.4.1**. Then use the set command to configure your own network settings. Alternatively connect the ESP8266 to your PC and open a Serial monitor to configure the settings. Make sure you disable Serial support before connecting the EMS lines using `set serial off`.
