Working Temperature

I want to place a sensor in a fridge where the working temperature can go as low as -180º C (-292F) or in a regular environment where it can be as high as 40ºc (104F).

Do you have any specs on the working environment the electronics of the zigbee can withstand?

Thanks in advance

the RTD probe can read but the transmitter box can not run at such low temp. that being said i never tried it such low temp

That being said, what is the working temperature reomended?

transmitter box -40C to 70C.
probe temp will depend on the probe specs
