Hi Volhoult, All,

I will/intend to,  be enclosing the PM and HC12 in the existing shell and coating the boards with conformal coating plus all the joins plus entry points will be covered with that dielectric gel.

I have a PM powered by a 2A 5v plug pack (for my PM based water tank gauge) directly under where I will be raising the weather station that is permanently ON so I will be running the 5V along with Serial console up some cat 5 to power the weather PM.

Everything will be permanently powered, data transmission depends on what it’s sending, rain can be fairly regular temperature not so etc. all short msg strings .

The location of the plug pack is outside but protected from the rain and has been there for a couple of years now.

I am considering an 18650 battery backup but may not.

Regards,

Mick
