Hostname

This name will identify this device in your network (http://<hostname>.local). For this setting to take effect you should restart the wifi interface clicking the "Reconnect" button.

Relay boot mode

Here you can define what will be the status of the relay after a reboot.

Relay sync mode

Define how the different relays should be synchronized.

Alexa integration

Admin password

The administrator password is used to access this web interface (user 'admin'), but also to connect to the device when in AP mode or to flash a new firmware over-the-air (OTA).
It should have at least eight characters (letters, numbers or the underscore) and at least one number, one lowercase and one uppercase letter.

Admin password (repeat)

HTTP API Key

This is the key you will have to pass with every HTTP request to the API, either to get or write values.

MQTT Root Topic

This is the root topic for this device. The {identifier} placeholder will be replaces by the device hostname.
- <root>/relay/# Send a 0 or a 1 as a payload to this topic to switch it on or off. You can also send a 2 to toggle its current state. Replace # with the relay ID (starting from 0). If the board has only one relay it will be 0.
- <root>/led/# Send a 0 or a 1 as a payload to this topic to set the onboard LED to the given state, send a 3 to turn it back to WIFI indicator. Replace # with the LED ID (starting from 0). If the board has only one LED it will be 0.
- <root>/ip The device will report to this topic its IP.
- <root>/version The device will report to this topic its firmware version on boot.
- <root>/status The device will report a 1 to this topic every few minutes. Upon MQTT disconnecting this will be set to 0.

Domoticz OUT Topic

AC RMS Active Power

In Watts (W). If you are using a pure resistive load like a bulb this will be writen on it, otherwise use a socket multimeter to get this value.

AC RMS Voltage

In Volts (V). Enter your the nominal AC voltage for your household or facility, or use multimeter to get this value.

AC RMS Current

In Ampers (A). If you are using a pure resistive load like a bulb this will the ratio between the two previous values, i.e. power / voltage. You can also use a current clamp around one fo the power wires to get this value.

Reset calibration

Move this switch to ON and press "Update" to revert to factory values.

WIFI

You can configure up to 5 different WiFi networks. The device will try to connect in order of signal strength.

MQTT

Configure an MQTT broker in your network and you will be able to change the switch status via an MQTT message. Leave the server field empty to disable MQTT.

DOMOTICZ

Configure the connection to your Domoticz server.

POWER

Calibrate your power monitor device. Use a pure resistive load and introduce the expected values for active power, current and voltage. Use the nominal values or a multimeter to get the proper numbers. Set any field to 0 to leave the calibration value untouched.
