EmonTX outside, subzero

Is it possible to mount the EmonTX outside, that is inside the electric "cabin" where incoming electric is ? How are the specs for humidity and temperature....we can reach -35 occasionally in wintertime even though it is uncommon these days.

Should be fine down to - 40 deg C according to ATmega328 and RFM69CW datasheet. I would expect humidity to be more of an issue than temperature. Should be fine as long as it's well sheltered and protected

Great! It should be well sheltered inside the electric-box. Thankyou!

batteries might freeze up :-D

what sensors are on?

you can give the board a spray of print laquer but if you have a humidity sensor you have to tape that off first so its not covered
