I’d like to get an outdoor Temperature Sensor that can be used with HA and Google Home. Anyone have any recommendations?

I use this one: https://www.aqara.com/us/temperature_humidity_sensor.html
If you already have ZigBee setup it’s easy to use these, if not maybe look for something else.
I also use one of these outside with a 3D printed case. Still going strong after about 18 months!
I have two of these outside, jankily sealed up with electrical tape, and they’ve survived the British weather for a year so far.
Same one I use, also made an enclosure to 3D print and protect it from rain. It’s been going on without issues since 2020 https://www.printables.com/model/169425-xiaomi-aquara-thermometer-outdoor-case
I’m not sure how you guys would feel about this… but I have a SDR connected to my Unraid server and found that a neighbor has one of those Acurite 5-1 weather stations that I can pick up on a 433mhz signal, parse the JSON file and added it to my dashboard. If you have a SDR sitting around you could scan your area and see what you get.
I second using an SDR with 433MHz devices. Incredibly reliable and low power.
Been using a nooelec SDR and one of these sensors:
Never thought of this approach.
So, what is it transmitting? Text? Or some form of numerical data?
I mean, how do I start? 🙂
It’s really easy. The rtl_sdr software interprets the info and passes out to HA. There’s an add-on that scans that info and looks for devices it recognizes, and adds then to HA as a sensor. You’ll get weather, tire pressure monitors, and other things.
Yup! In addition to temperature/humidity sensors, I’m also pulling in my gas meter and my home security sensors(I was using a big-name security company, but when my contract was up I kept the sensors installed and tapped into them with my SDR)
