Does anyone here have experience receiving from a froggit weather mast? http://www.froggit.de/product_info.php/info/p145_ersatz-ausseneinheit-komplett-wh1080-solar.html
It sends on 868 MHz

@cschneider often the data is encrypted. if you have a scope and a receiver for the specified bandwith you can try to decode the signal by hand. Otherwise what might be usefull is to find the rx and tx pins of the transmitter and try to read directly from that

@sticilface mdns packets ;) they are multicast so all local nodes get them

@rneurink The signal seems to be a simple encoding .. no encryption .. at least I found that on some site .. the problem is I do not even get the receiver working on esp 8266
I tried the rfm01 but was not able to receive anything with it
There also does not seem to be good docs about it .. Does anyone here know a good hardware that is easy to use as receiver?

@cschneider 868 Mhz is a weird frequency is it by any change related to LORA?
@cschneider is the problem related to not able to receive any data or does the receiver work with a regular arduino?

I did not yet check with arduino .. the only docs I found was for raspi .. so even arduino would need to be adapted

do you have an oscilloscope you can use?

No .. I tried to attach the sender directly to the analog port and used the plotter of the arduino ide
The output looked like a digital signal with fm modulation
but I have no idea how to decode it from that

What i understand from a bit of searching is that it should be an AM modulated signal. This is an post for the arduino http://www.susa.net/wordpress/2014/06/arduino-yun-reading-wh1080-using-aurel-rx-4mm5/ this post is probably the one you'll find the most. You'll need an OOK receiver to receive the data

@me-no-dev I did a bit of reading and discovered that. Stopping it and restarting solves it. I'm wondering if we can do something about it. The wifiudp class inherits from the class so u can stop all and stop all except. I'm wondering if we can extend that to the udpcontext so that they can be stop started and paused, as there are plenty of libs that role their own udp implementation using just udpcontext and not wifiudp.

@rneurink Thanks .. will look into it
