ADS-B Receiver is a fun project. With some pretty cheap hardware, you can track nearby planes.
Warning: This turned out way longer than I expected.
I'm in the US and I don't know how this would work with sensors that are available in Europe, but I'll share what I've been having success with lately.
I've been using cheap 433MHz sensors to measure temperature in a couple of locations using an RTL2832-based receiver (The one I'm using is a NooElec NESDR Mini 2+) and rtl_433.
I start rtl_433 in a screen session with the command:
rtl_433 -F json | mosquitto_pub -t home/rtl_433 -l
This tells rtl_433 to output in json format and pipes the result to mosquitto_pub (telling it to read from stdin with '-l').
On the MQTT side, the messages from my sensors appear formatted like this:
home/rtl_433 {"time" : "2017-04-10 15:06:11", "brand" : "OS", "model" : "THGR122N", "id" : 7, "channel" : 2, "battery" : "OK", "temperature_C" : 12.700, "humidity" : 23}
home/rtl_433 {"time" : "2017-04-10 15:06:15", "temperature" : 45.140, "humidity" : 70, "id" : 103, "model" : "LaCrosse TX141TH-Bv2 sensor", "battery" : "OK", "test" : "No"}
home/rtl_433 {"time" : "2017-04-10 15:06:51", "brand" : "OS", "model" : "THGR122N", "id" : 7, "channel" : 2, "battery" : "OK", "temperature_C" : 12.700, "humidity" : 23}
home/rtl_433 {"time" : "2017-04-10 15:06:52", "brand" : "OS", "model" : "THGR122N", "id" : 7, "channel" : 2, "battery" : "OK", "temperature_C" : 12.700, "humidity" : 23}
This is all nothing special. All of this stuff I just happened to have. The RTL2832 from a radio project I had been toying with. The sensors are a re-branded Oregon Scientific from an old, defunct temp/hygrometer, as well as the sensor from a LaCrosse weather station that I picked up on clearance a while back.
To get it into HA my config looks like this:
################
MQTT sensors #
Temperature
Humidity
Battery
Temperature
Humidity

Then I use a template to format it for display:
Outdoor Temperature
Outdoor Humidity
Garage Temperature
Garage Humidity
The end result, I get some cards and graphs. Woohoo!
As it see it, the pros of this approach are:
The cons:
You need a compatible LNB on the dish and an RTL-SDR dongle, like https://www.amazon.com/NooElec-NESDR-Mini-Receiver-RTL2832U/dp/B00VZ1AWQA
There are open source SDRs out there too... though they're fancier ones than the RTL-SDRs. In any case, it's all off the shelf parts. One of our major goals in this was to make the reception really low cost: the system is most useful if there are many receivers.
(Before you go rushing out to buy one: We don't cover Thailand yet. We need to build another uplink location out to cover that slice of the world. We're working on it!)
Either of these are going to do the job just fine. Expect to spend about a hundred bucks.

(edit: Removed the scanners that couldn't receive mil-air frequencies)
Take your pick between handheld or base scanner.
The Uniden BCT15X is a nice mid range base scanner for a little bit more.

Another good and cheap option is RTL-SDR. These inexpensive dongles are used with your computer and open up a whole world of cool stuff to do, from just basic listening to more advanced projects.

Here is the radio I am using and here is the tutorial on finding police frequencys and decoding them. I bought it to better understand radio waves for my signal analysis class and use it for days like these.
Thanks! I will start with something cheaper, but I understand is good quality.
I bought this https://www.amazon.it/gp/product/B00VZ1AWQA/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
It seems good enough for me even if it doesn't catch HF. Besides I would have problems with a long antenna anyway.
My next move will be an upconverter, maybe I can use a fraction of antenna, IDK. I still don't get what are good ratios of Antenna length/Lambda, but we will see. Thank you!
Thanks Everyone, I went ahead and just bought 2 new RTLSDR (https://www.amazon.com/gp/product/B00VZ1AWQA/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1) and some adapters for now (https://www.amazon.com/gp/product/B00RF15070/ref=oh_aui_detailpage_o00_s01?ie=UTF8&psc=1) Im hoping to use unitrunker with the 2 dongles and then eventually make an antenna to get NOAA Images
I just have the generic $20 NooElec. The cheaper ones may work too but I don't have any experience
these are the blog SDRs

which one are you ACTUALLY using..
To get started you'll need:
Once you have the pieces, you'll need to:
Would this be any good?
