Tasmota: Add ability to mark a pin as bad / do not use

[scottchiefbaker]

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

Yes? It's hard to search for this issue, so it's hard to say.

Is your feature request related to a problem? Please describe.

No

Describe the solution you'd like

I have an ESP8266 with a bad pin. It doesn't affect functionality of anything else, but I'd like to note that it's bad. I'm going to install this unit in my garage. If I decide to come back to it in a year or two and want to add a new sensor I want to make sure I don't use that bad pin.

It would be nice if there were a way to flag a pin as bad or do not use. This would persist in the config so when a user comes back in the future they'll know not to use that pin.

Describe alternatives you've considered

Currently I'm just flagging that pin as a "BUZZER" which hopefully I'll remember is something I never use and it really means "bad".

Additional context

This is just a "nicety" not a requirement.

I work in the telco field and we have various cards with 100s of interfaces and it's not uncommon to see an interface marked as bad for whatever reason. Saves a lot of headaches in the future trying to figure out where to put the next circuit / sensor.

How about use a simple template?
In a template you can block gpio usage, one by one.

Prepare your template from GUI or quickly from console:

21:17:56 template 255

21:17:56 MQT: stat/tasmota_2350B0/RESULT = {"NAME":"Merged","GPIO":[255,255,255,255,25,22,255,255,255,9,255,255,255],"FLAG":15,"BASE":18}

Let's say GPIO12 is not working, now that you have your base template simply edit it from console or better from the GUI:
Configuration--> Configure Template:

Then update it removing the offending GPIO (12 in our case) and give it a meaningful name:

Now simply apply it from console with the command Module 0 or from the GUI under
Configuration --> Configure Other --> Template and hit activate.
As a result your broken pin will be gone:

Now your template is ready to be deployed in every device you need.
