An outdoor version of the t315 would be very welcome!

  @Joao_Pereira totally agree with you. Hope it will be on the roadmap asap. 

  @Doodik you can encapsulate a T310 simply in a surface-mounted junction box for damp locations. they have IP54 protection, but are not sealed, so the sensor is protected but still exposed to the surrounding temp and air humidity conditions. i have two working outdoor in rather different climates since more than 18 months, no problems.

also i encapsuled a T110 in a little microdevice box (4x screwed top; i added a diy sealing made of a bicycle tube). the counterpart, containing nothing else as a little magnet, was replaced with a little bare neodym.

using standard neodym magnets instead of the original counterpart is also a great solution for narrow spaces.

nevertheless, outdoor sensors out of the shelf should be a great thing.
