Earlier quoted context omitted.
My first thought was, "Why would I need SDR to read temperature/humidity from sensors", then I realized these are more like wireless weather stations. Out of curiosity: why did you decide to purchase ready solutions instead of rolling your own using ESP32 for a fraction of the price?
Not the person you replied to, but someone who did the same thing: Most of the things inside my house are ESP32 or zigbee things I put together myself. Things that go outdoors, though, I'm much more likely to purchase an off-the-shelf solution for longevity's sake. Especially if the whole point of the item is to be rained/snowed on, be left in direct sunlight, and so forth.
You can always build a tiny little house for your outside ESP and leave it outside.
