I'm unaware that the WeatherFlow gear can be run at all without a Hub. The Hub emits the UDP broadcast to your 2.4 GHz wifi network which other gear can read. You also need the Hub connected out to to Internet so it can receive sensor tunings from the WF servers. Even if you 'could' sniff the RF from the sensor suite you wouldn't have any tunings of those readings toward anything approaching reality, so you'd be sniffing garbage.
Doing a roll your own indoor sensor setup is a well-known thing, but you'd want something more than a PiZero since that doesn't have wired ethernet. Yes you need to keep the sensors away from any heat sources including the pi themselves. I would not suggest a HAT for that, you want something more like a breadboard some distance from the pi. Putting an environmental HAT on the pi pretty much guarantees incorrect data. You can buy a whole replacement ISS suite for your Vue for half the price of a WF Tempest setup. Check out scientificsystems.com and scaledinstruments.com for a couple of the generally most inexpensive Davis gear sellers. I've had great luck with both sellers. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
