4. Build and upload the firmware to the ESP8266 device. I used Platformio with Visual Studio. Do make sure you set the MQTT and WiFi credentials correctly and if you're not using MQTT leave the MQTT_IP blank. The firmware supports OTA too with the default hostname as 'boiler' (or 'boiler.' depending on your OS and how the mdns resolves hostnames).
5. Power the ESP either via USB or direct into the 5v vin pin from an external power 5V volts supply with min 400mA.
6. Attach the 3v3 out on the ESP8266 to the DC power line on the EMS circuit as indicated in the schematics.
7. The WiFi connects via DHCP. Find the IP by looking at your router and then telnet (port 23) to it. I use the telnet client that comes with my Linux distro on Windows 10 (in developer mode) but you can also use [putty](https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html) or anything similar. If everything is working you should see the messages appear in the window as shown in the next section. However if you're unable to locate the IP of the ESP then probably the WiFi failed to instantiate. In this case add -DUSE_SERIAL to the build options, connect at USB, build, upload and then use a terminal to connect to the serial port to see the debug messages. A word of warning, do not use both a USB and power from the EMS at the same time.
7. The WiFi connects via DHCP by default. Find the IP by from your router and then telnet (port 23) to it. Hint: to enable Telnet on Windows run `dism /online /Enable-Feature /FeatureName:TelnetClient` or install something like [putty](https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html).
