How can I detect the power monitoring capability ?

[wjohn007]

I intend to write a Berry script for multiple controllers.
Not all of them support power monitoring.
How can I determine whether the specific controller supports power monitoring?
I would prefer to use the Berry Module Energy for this.

Thank you very much for the support.

That depends on what you even mean by "controller". If what you mean is a Tasmota device correctly configured for energy monitoring, the data will be available with other sensor data.

The Berry script is intended to detect whether energy monitoring is configured and available for the current Tasmota-Controller.

Well, as I mentioned, energy monitoring numbers will be available as part of the sensor data. In Berry, you could use tasmota.read_sensors and check if the JSON (parsed into a map) contains the ENERGY object.

Thank you for the hint.
This solves my requirement:

json.load(tasmota.read_sensors()).contains('ENERGY')
