+# Enphase Binding
+
+This is the binding for the [Enphase](https://enphase.com/) Envoy Solar Panel gateway.
+The binding uses the local API of the Envoy gateway.
+Some calls can be made without authentication and some use a user name and password.
+The default user name is `envoy` and the default password is the last 6 numbers of the serial number.
+The Envoy gateway updates the data every 5 minutes.
+Therefore using a refresh rate shorter doesn't provide more information.
+
+## Supported Things
+
+The follow things are supported:
+
+* `envoy` The Envoy gateway thing, which is a bridge thing.
+* `inverter` A Enphase micro inverter connected to a solar panel.
+* `relay` A Enphase relay.
+
+Not all Envoy gateways support all channels and things.
+Therefore some data on inverters and the relay may not be available.
+The binding auto detects which data is available and will report this in the log on initialization of the gateway bridge.
+
+## Discovery
+
+The binding can discover Envoy gateways, micro inverters and relays.
+
+## Thing Configuration
+
+The Envoy gateway thing `envoy` has the following configuration options:
+
+| parameter | required | description |
+|--------------|----------|-------------------------------------------------------------------------------------------------------------|
+| serialNumber | yes | The serial number of the Envoy gateway which can be found on the gateway |
+| hostname | no | The host name/ip address of the Envoy gateway. Leave empty to auto detect |
+| username | no | The user name to the Envoy gateway. Leave empty when using the default user name |
+| password | no | The password to the Envoy gateway. Leave empty when using the default password |
+| refresh | no | Period between data updates. The default is the same 5 minutes the data is actual refreshed on the Envoy |
+
+The micro inverter `inverter` and `relay` things have only 1 parameter:
+
+| parameter | required | description |
+|--------------|----------|-----------------------------------|
+| serialNumber | yes | The serial number of the inverter |
+
+## Channels
+
+The `envoy` thing has can show both production as well as consumption data.
+There are channel groups for `production` and `consumption` data.
+The `consumption` data is only available if the gateway reports this.
+A example of a production channel name is: `production#wattsNow`.
+
+| channel | type | description |
+|--------------------|---------------|---------------------------------------|
+| wattHoursToday | Number:Energy | Watt hours produced today |
+| wattHoursSevenDays | Number:Energy | Watt hours produced the last 7 days |
+| wattHoursLifetime | Number:Energy | Watt hours produced over the lifetime |
+| wattsNow | Number:Power | Latest watts produced |
+
+The `inverter` thing has the following channels:
+
+| channel | type | description |
+|-----------------|--------------|--------------------------------------|
+| lastReportWatts | Number:Power | Last reported power delivery |
+| maxReportWatts | Number:Power | Maximum reported power |
+| lastReportDate | DateTime | Date of last reported power delivery |
+
+The following channels are only available if supported by the Envoy gateway:
+
+The `relay` thing has the following channels:
+
+| channel | type | description |
+|-----------------|--------------|--------------------------------------------------------|
+| relay | Contact | Status of the relay. |
+| line1Connected | Contact | If power line 1 is connected. If closed it's connected |
+| line2Connected | Contact | If power line 2 is connected. If closed it's connected |
+| line2Connected | Contact | If power line 3 is connected. If closed it's connected |
+
+The `inverter` and `relay` have the following additional advanced channels:
+
+| channel | type | description |
+|-----------------|--------------------|--------------------------------------|
+| producing | Switch (Read Only) | If the device is producing |
+| communicating | Switch (Read Only) | If the device is communicating |
+| provisioned | Switch (Read Only) | If the device is provisioned |
+| operating | Switch (Read Only) | If the device is operating |
+
+## Full Example
+
+Things example:
+
+```
+Bridge enphase:envoy:789012 "Envoy" [ serialNumber="12345789012" ] {
+ Things:
+ inverter 123456 "Enphase Inverter 123456" [ serialNumber="789012123456" ]
+ inverter 223456 "Enphase Inverter 223456" [ serialNumber="789012223456" ]
+}
+```
+
+Items example:
+
+```
+Number:Power envoyWattsNow "Watts Now [%d %unit%]" { channel="enphase:envoy:789012:production#wattsNow" }

+Number:Energy envoyWattHoursLifetime "Watt Hours Lifetime [%.1f kWh]" { channel="enphase:envoy:789012:production#wattHoursLifetime" }
+
+Number:Power i1LastReportWatts "Last Report [%d %unit%]" { channel="enphase:inverter:789012:123456:lastReportWatts" }
+Number:Power i1MaxReportWatts "Max Report [%d %unit%]" { channel="enphase:inverter:789012:123456:maxReportWatts" }

+
+Number:Power i2LastReportWatts "Last Report [%d %unit%]" { channel="enphase:inverter:789012:223456:lastReportWatts" }
+Number:Power i21MaxReportWatts "Max Report [%d %unit%]" { channel="enphase:inverter:789012:223456:maxReportWatts" }
