I've developed a new plugin for Domoticz that retrieves photovoltaic (PV) production forecasts from Forecast.Solar and makes them available as devices in Domoticz.
The goal is to make solar production forecasts easy to integrate into your home automation, energy monitoring and automation scripts.
Features
- []Remaining Today – Forecast energy production from the current time until midnight.
[]Tomorrow Forecast – Estimated total PV production for the next calendar day.
[]Next Hour Forecast – Estimated PV production for the next complete clock-hour interval.
[]Status – Displays the last update status.
[]Automatic device creation.
[]Configurable through a .env file. - Energy forecasts reported in kWh.
The latest release introduces the Next Hour Forecast sensor.
For example, at 17:44, the forecast covers 18:00–19:00 rather than a rolling 60-minute period.
This can be useful for automations that depend on expected solar production during the next hour.
Example Use Cases
- []Optimize EV charging based on expected solar production.
[]Schedule appliances when sufficient PV energy is expected.
[]Improve energy management using today's remaining and tomorrow's forecast.
[]Use forecast values in Domoticz scripts and other automations.

Feedback and Contributions
The plugin is under active development, and feedback is welcome!
If you encounter a problem, please open an issue on GitHub and include the relevant Domoticz logs, with any personal information or API credentials removed.
Suggestions, bug reports and contributions are appreciated.
Happy automating!
