GENERAL

General configuration values

This name will identify this device in your network (http://<hostname>.local).
Hostname may contain only the ASCII letters 'a' through 'z' (in a case-insensitive manner), the digits '0' through '9', and the hyphen ('-'). They can neither start or end with an hyphen.
For this setting to take effect you should restart the wifi interface by clicking the "Reconnect" button.
Human-friendly name for your device. Will be reported with the heartbeat.
You can use this to specify the location or some other identification information.
Delay in milliseconds to detect a double click (from 0 to 1000ms).
The lower this number the faster the device will respond to button clicks but the harder it will be to get a double click. Increase this number if you are having trouble to double click the button. Set this value to 0 to disable double click. You won't be able to set the device in AP mode manually but your device will respond immediately to button clicks.
You will have to reboot the device after updating for this setting to apply.
This setting defines the behaviour of the main LED in the board.
When in "WiFi status" it will blink at 1Hz when trying to connect. If successfully connected it will briefly blink every 5 seconds if in STA mode or every second if in AP mode.
When in "Relay status" mode the LED will be ON whenever any relay is ON, and OFF otherwise. This is global status notification.
When in "MQTT managed" mode you will be able to set the LED state sending a message to "<base_topic>/led/0/set" with a payload of 0, 1 or 2 (to toggle it).
When in "Find me" mode the LED will be ON when all relays are OFF. This is meant to locate switches at night.
When in "Relay & WiFi" mode it will follow the WiFi status but will stay mostly off when relays are OFF, and mostly ON when any of them is ON.
When in "Find me & WiFi" mode is the opposite of the "Relay & WiFi", it will follow the WiFi status but will stay mostly on when relays are OFF, and mostly OFF when any of them is ON.
"Always ON" and "Always OFF" modes are self-explanatory.

SWITCHES

Switch / relay configuration

General
Define how the different switches should be synchronized.

LIGHTS

Lights configuration

Use the first three channels as RGB channels. This will also enable the color picker in the web UI. Will only work if the device has at least 3 dimmable channels.
Reload the page to update the web interface.
Use RGB color picker if enabled (plus brightness), otherwise use HSV (hue-saturation-value) style
Use forth dimmable channel as (cold) white light calculated out of the RGB values.
Will only work if the device has at least 4 dimmable channels.
Enabling this will render useless the "Channel 4" slider in the status page.
Reload the page to update the web interface.
Use fifth dimmable channel as warm white light and the forth dimmable channel as cold white.
Will only work if the device has at least 5 dimmable channels and "white channel" above is also ON.
Enabling this will render useless the "Channel 5" slider in the status page.
Reload the page to update the web interface.
Use gamma correction for RGB channels.
Will only work if "use colorpicker" above is also ON.
Use CSS style to report colors to MQTT and REST API.
Red will be reported as "#FF0000" if ON, otherwise "255,0,0"
If enabled color changes will be smoothed.
Time in millisecons to transition from one color to another.
Sync color between different lights.

ADMINISTRATION

Device administration and security settings

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 must be 8..63 characters (numbers and letters and any of these special characters: _,.;:~!?@#$%^&*<>\|(){}[]) and have at least one lowercase and one uppercase or one number.
This is the port for the web interface and API requests. If different than 80 (standard HTTP port) you will have to add it explicitly to your requests: http://myip:myport/
If enabled, API requests to change a status (like a relay) must be done using PUT. If disabled you can issue them as GET requests (easier from a browser).
By default, some magnitudes are being preprocessed and filtered to avoid spurious values. If you want to get real-time values (not preprocessed) in the API turn on this setting.
This is the key you will have to pass with every HTTP request to the API, either to get or write values. All API calls must contain the apikey parameter with the value above. To know what APIs are enabled do a call to /apis.
Turn ON to be able to telnet to your device while connected to your home router.
TELNET is always enabled in AP mode.
Request password when starting telnet session
Define when heartbeat message will be sent.
This is the interval in seconds how often to send the heartbeat message.
The device has bytes available for OTA updates. If your image is larger than this consider doing a two-step update.

WIFI

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

General
Device hostname can be configured on the GENERAL tab.
ESPurna will scan for visible WiFi SSIDs and try to connect to networks defined below in order of signal strength, even if multiple AP share the same SSID. When disabled, ESPurna will try to connect to the networks in the same order they are listed below. Disable this option if you are connecting to a single access point (or router) or to a hidden SSID.
Networks

SCHEDULE

Turn switches ON and OFF based on the current time.

MAPPING

Configure the map between nodeID/key and MQTT topic. Messages from the given nodeID with the given key will be forwarded to the specified topic. You can also configure a default topic using {nodeid} and {key} as placeholders, if the default topic is empty messages without defined map will be discarded.

Default topic
Specific topics

MESSAGES

Messages being received. Previous messages are not displayed. You have to keep the page open in order to keep receiving them. You can filter/unfilter by clicking on the values. Left click on a value to show only rows that match that value, middle click to show all rows but those matching that value. Filtered colums have red headers.

Timestamp SenderID PacketID TargetID Key Value RSSI Duplicates Missing

MQTT

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

You can use the following placeholders: {hostname}, {mac}
If left empty the firmware will generate a client ID based on the serial number of the chip. You can use the following placeholders: {hostname}, {mac}
This is the fingerprint for the SSL certificate of the server.
You can get it using https://www.grc.com/fingerprints.htm
or using openssl from a linux box by typing:
$ openssl s_client -connect <host>:<port> < /dev/null 2>/dev/null | openssl x509 -fingerprint -noout -in /dev/stdin
This is the root topic for this device. The {hostname} and {mac} placeholders will be replaced by the device hostname and MAC address.
- <root>/relay/#/set 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 switch ID (starting from 0). If the board has only one switch it will be 0.
- <root>/rgb/set Set the color using this topic, your can either send an "#RRGGBB" value or "RRR,GGG,BBB" (0-255 each).
 - <root>/hsv/set Set the color using hue (0-360), saturation (0-100) and value (0-100) values, comma separated.
 - <root>/brightness/set Set the brighness (0-255).
 - <root>/channel/#/set Set the value for a single color channel (0-255). Replace # with the channel ID (starting from 0 and up to 4 for RGBWC lights).
 - <root>/mired/set Set the temperature color in mired.
 - <root>/status The device will report a 1 to this topic every few minutes. Upon MQTT disconnecting this will be set to 0.
- Other values reported (depending on the build) are: firmware and version, hostname, IP, MAC, signal strenth (RSSI), uptime (in seconds), free heap and power supply.
All messages (except the device status) will be included in a JSON payload along with the timestamp and hostname and sent under the <root>/data topic.
Messages will be queued and sent after 100ms, so different messages could be merged into a single payload.
Subscriptions will still be done to single topics.

SENSOR CONFIGURATION

Configure and calibrate your device sensors.

General
Select the interval between readings. These will be filtered and averaged for the report. Please mind some sensors do not have fast refresh intervals. Check the sensor datasheet to know the minimum read interval. The default and recommended value is 6 seconds.
Select the number of readings to average and report
Save aggregated data to EEPROM after these many reports. At the moment this only applies to total energy readings. Please mind: saving data to EEPROM too often will wear out the flash memory quickly. Set it to 0 to disable this feature (default value).
Temperature correction value is added to the measured value which may be inaccurate due to many factors. The value can be negative.
Humidity correction value is added to the measured value which may be inaccurate due to many factors. The value can be negative.
Move this switch to ON and press "Save" to reset gas sensor calibration. Check the sensor datasheet for calibration conditions.
Energy monitor
Mains voltage in your system (in V).
In Amperes (A). If you are using a pure resistive load like a bulb, this will be the ratio between the two previous values, i.e. power / voltage. You can also use a current clamp around one of the power wires to get this value.
In Volts (V). Enter your the nominal AC voltage for your household or facility, or use multimeter to get this value.
In Watts (W). Calibrate your sensor connecting a pure resistive load (like a bulb) and enter here its nominal power or use a multimeter.
Energy ratio in pulses/kWh.
Move this switch to ON and press "Save" to revert to factory calibration values.
Move this switch to ON and press "Save" to set energy count to 0.

RADIO FREQUENCY

Sonoff 433 RF Bridge & RF Link Configuration

This page allows you to configure the RF codes for the Sonoff RFBridge 433 and also for a basic RF receiver.

To learn a new code click LEARN (the Sonoff RFBridge will beep) then press a button on the remote, the new code should show up (and the RFBridge will double beep). If the device double beeps but the code does not update it has not been properly learnt. Keep trying.

Modify or create new codes manually and then click SAVE to store them in the device memory. If your controlled device uses the same code to switch ON and OFF, learn the code with the ON button and copy paste it to the OFF input box, then click SAVE on the last one to store the value.

Delete any code clicking the FORGET button.

You can also specify 116-chars long RAW codes. Raw codes require a specific firmware for for the EFM8BB1.
