# Enphase Binding

This is the binding for the Enphase (opens new window) 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" ]
