I have been searching for and testing various supported outdoor temp sensors for use in a sauna which is located about 120 feet away from the 433trx with only limited success.
Most of the readily available RFX supported outdoor sensors (Oregon, Meade, LaCrosse) have range limitations (≈100 ft) which will not work from inside the sauna (or from the crawlspace above when used with a remote probe into sauna).
I have successfully been able to receive a reliable signal with the Oregon AW131 meat thermometer (advertised range of 330 feet), but it has an auto-shutoff feature which can not be disabled (and therefore of no use for consistent temperature monitoring). Any suggestions that you may have for a long range outdoor rated sensor (70+ meters) which can report up to 157℉ (70℃) would be most appreciated. One with an external dry probe would be even better.
Alternatively, anyone who can share their success with another input protocol (Insteon, Zwave, hardwired, etc.) would be much appreciated (Zwave is weak in this area of property, even with Aeotec extender). I couldn't get the the Insteon thermostats (2441TH and 2441 THZ) to work (external sensor does not report to Indigo). I also have an easyDAQ (if a hardwired sensor solution exists), but connecting the wiring to the sauna would be time consuming and invasive.
Thanks,
