+# Iammeter Binding 
+
+[Iammeter](https://www.iammeter.com) provides real-time readings of single-phase (WEM3080, WEM3162) and three-phase (WEM3080T) meters from IAMMETER over Wi-Fi.
+
+## Use of the binding
+
+The Iammeter is exposed as one thing with a number of channels that can be used to read the values for different aspects of your Iammeter devices. 
+
+## Setup of the binding
+
+You can add the Iammeter device via the openHAB UI manually.
+
+
+## Available channels
+
+The following table is taken from the official manual and contains all available channels.
+
+Single-phase energy meter (WEM3080/WEM3162)
+|Name|Unit|Description|Type|
+|----|----|----|----|
+|voltage_a|V|Voltage|Number|
+|current_a|A|Current|Number|
+|power_a|W|Active power|Number|
+|importenergy_a|kWh|Energy consumption from gird|Number|
+|exportgrid_a|kWh|Energy export to grid|Number|
+
+Three-phase energy meter (WEM3080T)
+|Name|Unit|Description|Type|
+|----|----|----|----|
+|voltage_a|V|A phase voltage|Number|
+|current_a|A|A phase current|Number|
+|power_a|W|A phase active power|Number|

+|exportgrid_a|kWh|A phase export energy|Number|
+|frequency_a|kWh|A phase frequency|Number|
+|pf_a|kWh|A phase power factor|Number|
+|voltage_b|V|B phase voltage|Number|
+|current_b|A|B phase current|Number|
+|power_b|W|B phase active power|Number|
+|importenergy_b|kWh|B phase import energy|Number|
+|exportgrid_b|kWh|B phase export energy|Number|
+|frequency_b|kWh|B phase frequency|Number|
+|pf_b|kWh|B phase power factor|Number|
+|voltage_c|V|C phase voltage|Number|
+|current_c|A|C phase current|Number|
