Send wifi signal strength to HomeAssistant automatic discovery

[jrhbcn]

Hi,

Tasmota both reports RSSI and Signal Strength for WiFi connection (following issues #7113 and PR #7145). However, only RSSI is added back to Home Assistant and Signal Strength is missing in automatic discovery. I am trying to unify the wifi reporting of all my IoT devices (it is a nightmare! but the majority seems to report dBm). Would it be possible to add this into Home Assistant discovery?

Thanks!

Have you looked for this feature in other issues and in the docs?
Yes

Is your feature request related to a problem? Please describe.
No

Describe the solution you'd like
It'd be good to have the same info in the status mqtt topic as attributes in Home Assistant.

Describe alternatives you've considered
Convert RSSI to signal strength directly in Home Assistant but the entity cannot be added automatically to the Tasmota Device and looks as if an standalone entity.

Additional context

As you probably knows, we have already dBm signal in information page:

EffE-WiFi (76%, -62 dBm)

RSSI is already used in Home Assistant for metrics and to have dBm too a new sensor must be created, because a combined sensor with RSSI and dBm can't be used on history, meaning code repetition and then greater space used on program memory.
What I can do is to add the dBm value on the resume list of status sensor that will limit the space used, but will be not an information available for history.

I think that is almost perfect. Info will be accessible to HomeAssistant (to create automations, etc.) and even if not available directly for history it could be forwarded to influxdb/grafana if history is needed anyway.

Many thanks for looking into this and let me know if you need someone to test the solution.

Ok, I was about to change the resume list anyway.
I'll add dBm on next update.
