Tasmota: Add a prometheus build

[MorrisJobke]

Have you looked for this feature in other issues and in the docs?
Yes, there is a directive USE_PROMETHEUS available but not used in any current build: #9204

Is your feature request related to a problem? Please describe.
Enabling the USE_PROMETHEUS build flag on either an existing or a new build would help to use the /metrics endpoint and lower the barrier. Compiling the new firmware on each update is more work for each of the users if the builds can be done automatically here in the project itself.

Describe the solution you'd like
Enabling the USE_PROMETHEUS in a build that suits this. Either the tasmota one or a dedicated tasmota-prometheus flavor.

Describe alternatives you've considered
Building the release by myself - but this is a higher barrier also for others and joining forces helps maybe.

Additional context
n/a

Thanks for this nice project 🙌

Hi,

Prometheus uses few FLASH and RAM, so I don't see that will worth to add a new flavour with just one more feature. So, a new Tasmota Firmware type seems not to be added.

For adding the directive USE_PROMETHEUS to the full _Tasmota_ firmware type OR to the _Tasmota-Sensors_ firmware type, let's see how many people will need this.

Adding the label FEATURE REQUEST to this issue and let's see how many hits it have.

Thanks for sharing your ideas

you can submit a new build to https://github.com/tasmota/binaries/tree/circleci-build and it will be automatically built daily

Closing this request as it had no hits from the community and as the flash space is very restricted on the esp8266, it will be used for other features. Sorry.

Thanks for sharing your ideas.
