I’ve been trying to find a nice temperature sensor I can put outside and have it be reliable for many years. I’m on my third replacement of cheap 433MHz temperature sensors from weather stations, and they start reading weird after a year or two.
I do like the low power aspect of 433MHz, two AA batteries last 2 years with these things. But the way they’re built is… a circuit board with a NTC thermistor, everything exposed to the elements.
Anyone have any experience with a nice 433MHz temperature I can use outdoors without worrying about it going bad? I like this IP66 one, for example, but haven’t tried it yet to see if it works with OMG or RTL_433: Ecowitt WN34L
