Manual meter readings (non-smart meters)

[andrewpwade]

Describe the feature

The API appears to provide access to meter readings that you submit manually. This could be useful just to track and graph in HomeAssistant.

I'm an experienced developer proficient in Python and could develop this feature if it's desired.

Expected behaviour

Manual meter readings tracked by this software

Use Case

I do not have a smart meter, but I would still like to track and graph my usage.

Hello and thanks for the feature request. This hasn't been a high priority as most people that use this integration have a smart meter. I'm not sure when I'll get to it, but you're more than welcome to submit a pull request if you'd like to contribute a solution. The requirements I'd expect would be

• Update to API client to get latest reading for electricity/gas
• Integration test for the above call
• Coordinator per electricity/gas meter to obtain the latest reading and return the results. This should follow the current pattern with retries/fallbacks if the information cannot be retrieved. Data should be retrieved at a rate of once every 6 hours (as the data doesn't change too often)
• New sensor, disabled by default, which displays the latest reading with correct unit of measurement. Unique id should be octopus_energy_electricity_{self._serial_number}_{self._mpan}_last_manual_reading. For gas, there should be one in m3 and one in kwh which should be calculated where appropriate (similar to accumulative consumption). Sensors should include an attribute with the timestamp that the meter reading was captured (as this would probably be useful for automations/reminders).
• Unit tests for coordinator and any new functions required for above sensor to function
• Update to docs to include information on new sensor(s).
