RCT Power integration

This component will set up the following platforms.

Platform	Description
sensor	Show info from RCT Power API.

Installation

Via the HACS integration

1. Install the "RCT Power" integration using HACS.
2. In the HA UI go to "Configuration" -> "Integrations" click "+" and search for "RCT Power"

Via manual download

1. Using the tool of choice open the directory (folder) for your HA configuration (where you find configuration.yaml).
2. If you do not have a custom_components directory (folder) there, you need to create it.
3. In the custom_components directory (folder) create a new folder called rct_power.
4. Download all the files from the custom_components/rct_power/ directory (folder) in this repository.
5. Place the files you downloaded in the new directory (folder) you created.
6. Restart Home Assistant
7. In the HA UI go to "Configuration" -> "Integrations" click "+" and search for "RCT Power"

Configuration

Upon installation the integration accepts the following configuration parameters:

• Host name: The local IP address or host name of the inverter.
• Port: The port of the inverter's API, defaults to 8899.
• Name: This name is used as a prefix to the entities created by this integration and can be used to disambiguate multiple inverters.

After installation the integration allows for the following configuration parameters to be changed:

• Frequent polling interval: The polling interval in seconds for entities updated frequently, defaults to 30.
• Infrequent polling interval: The polling interval in seconds for entities updated infrequently, defaults to 180.
• Static polling interval: The polling interval in seconds for entities updated seldomly, defaults to 3600.

Usage with the built-in energy dashboard

You can use the entities provided by this integration on Home Assistant's built-in energy dashboard. For that purpose, navigate to "Configuration" -> "Energy" and choose the following entities.

Please note that the entity names in your installation are prefixed with the inverter name chosen during installation of the integration, so interpret the entity names mentioned below to be entity name suffixes.

Also note that after configuration the energy dashboard might take several hours to show any data, because Home Assistant calculates the underlying statistics only on an hourly basis.
