Component doesn't support minimum temperature below 0.

Component doesn't support minimum temperature below 0, but for north regions it's quite important.

Winter is coming - good catch...

What do you suggest is a reasonable minimum?
-10? Maybe a bit low (high?). It might trigger alerts during cold winter days.
-50? Is this a reasonable minimum? Do any plants (or even the temperature sensors) actually survive -50 for a longer period of time?
-100? According to this article, the coldes places on earth are the Eastern Antarctic Plateau (-94°C) and Vostok Station Antarctica (-89.2°C). But I don't think there are many plants living outdoors there...

hm... I don't know how the code handles this here - but I think, the "minimum" temperature should be, what OpenPlantBook provides for a specific plant?
If you do set the minimum temperature manually, I would just accept the input of the user, without checking if it is -10 or -50 or what ever...

Does it really need to 'validate' the input?

[Olen]

An input_number requires a max and min value

hm... I would then go with +50 / -50
That should be OK in 98% of the cases ;)

Ordinary cheap off the shelf weather temperature sensors such as accurite and echowitt with lithium iron disulfide (so called "lithium metal') batteries like the "Energizer Ultimate Lithium" work just fine from -50°C to +60°C (I use them all the time in deep freezers and in lab ovens), which is basically "central alaska in the winter" to "death valley in july at noon" temperatures, and plants survive in those environments.

Added a quick patch.
Max can still be 0 - 100 (guess no plants have a negative max temperature)
Min can now be -50 - +50 (guess no plants have a minimum temperature higher than +50)
