# TasmotaPlug Binding

This binding connects Tasmota flashed smart plugs with 1, 2, 3 or 4 relay channels to openHAB. The plug must report the status of the relay via the url http://$PLUG_IP/cm?cmnd=Power in order for the binding to work. The energy monitoring channels can be used if the plug reports energy status via the url http://$PLUG_IP/cm?cmnd=Status%2010. See the Tasmota Supported Devices Repository (opens new window) for a list of supported plugs.

# Supported Things

There is exactly one supported thing type, which represents any supported Tasmota smart plug. It has the plug id. Multiple Things can be added if more than one plug is to be controlled.

# Discovery

Discovery is not supported. All things must be added manually.

# Thing Configuration

At minimum, the host name must be specified. The refresh interval and number of channels can be overridden from the default.

Parameter Description
hostName The host name or IP address of the plug. Mandatory.
refresh Overrides the refresh interval of the plug status. Optional, the default is 30 seconds.
numChannels Number of channels on the Tasmota Plug (1-4). Optional, the default is 1
username Username for authentication with the Tasmota Plug. Default 'admin'
password Password for authentication with the Tasmota Plug, if not supplied auth is disabled.

# Channels

The number of channels depends of on the numChannels configuration parameter. Channels above the number specified are automatically removed. Therefore numChannels cannot be changed upward after Thing creation. If the number of channels must be increased, delete the Thing and re-create it with the correct number.

Channel ID Item Type Description
power Switch Turns the smart plug relay #1 ON or OFF
power2 Switch Turns the smart plug relay #2 ON or OFF
power3 Switch Turns the smart plug relay #3 ON or OFF
power4 Switch Turns the smart plug relay #4 ON or OFF
