Does anyone know of any Battery Operated Outdoor Button type devices? Looking for something cheap. Zwave LR would be awesome but zigbee might work too. It's going to be about 30 ft from the house. Looking for something under $50 if possible.
This is lame but I use Aqara/Xiaomi buttons in the yard-in a ziplock bag.
I have a repeater in my shed 15M away from the house. I have never unplugged the repeater to see if they work directly but given it's free space it should; I have 2 repeaters on each end of the house rear just inside the windows.
I've been using Lutron picos, I have 6 of them outside none have any special weather protection, one is actually mounted on a block wall and is exposed to rain. Where I live we get temperatures from 25 to 125F, all 6 have been working flawlessly on the same batteries for almost 4 years now...
I also went the vacuum sealer route suggested by @aaiyar and included a "dry-pack". It was a bluetooth temp sensor with LCD readout: In a shaded area, over an extended period, pooled water sitting above the screen was able to penetrate the plastic. It's entirely possible the plastic was damaged somewhere. Just something to bare in mind with placement. I intend to do the same thing when I get around to putting temp sensors in the fridge and freezer etc.
