# One Channel WiFi Relay/Thermostat Board
The One Channel WiFi Relay/Thermostat Board is a WiFi connected multi-purpose relay board based on the [ESP8266 SoC].
**NOTE**: The board connects to and controls high voltage, knowledge and care is required to handle it
## [User Guide](docs/guide.md)
## Highlights
- Option for on-board power supply
- Powered by the WiFi [ESP8266 SoC] module
- HTTP API to control the relays
- [MQTT] support
- [NTP] for network time
- HTTP daemon settings, including security/authentication setup
- HTTP UI for configuration and control
- Thermostat function with weekly scheduling
- Manual relay control
- Broadcast using HTTP GET to services like [ThingSpeak] and [emonCMS]
- Integration with [ThingSpeak] for charting/analytics visualization
- Temperature sensor support
- DS18B20
- DHT22

## Firmware
Open Source firmware options:
- This OpenEnergyMonitor fork of Martin Harizanov's original repository contains an adaptation of the [3 channel relay firmware](https://github.com/mharizanov/ESP8266_Relay_Board) for 1 channel use.
- Alternatively [EmonESP](https://github.com/openenergymonitor/emonesp) can also be used.
## Using serial input for an external temperature sensor
Details thanks to Felix Paliuc:
- First setup the "serial" as the input for the sensor.
The temperature value must be sent in a particular way:
- First you have to send an "\n" which gets interpreted as a command.
- After that, you have to send the temperature value like this: serialremotetemp=
- The value of the temperature must be between -3000 and 12000 which gets divided by 100 later.
- Practically, I hooked a moteino to the Rx of the ESP8266 and configured the sketch to send temperature with a line like this:
Serial.print("\nserialremotetemp=1500");
