Multiple Results

Sorry if I have missed the function if it is already there. 

My LaCrosse sends temp, humidity and rain as three sequential packets. I use -E quit to exit on the first packet received, but is there a way of saying something like -E 3 to indicate don't quit until after first three packets decoded?

Thanks, Mike

That's not a use-case we have considered so far.

It might be interesting to revisit the requirement, why do you want rtl_433 to quit?

[MikeTheBee]

I have the RTLSDR usb stick on a RaspberryPi that does RTL_433 and other home-automation sensing tasks, including Weather Satellite tracking, so I disconnect RTL_433 between sensing cycles. It works well but I was looking to see if I can slim down my parsing scripts.

So multiplexing access to the RTL-SDR. Yes, that needs to quit rtl_433 (unless it's the same band, then maybe try the rtl_tcp pass-through).

Options might be to run rtl_433 for a fixed time (guessing the LaCrosse sends fairly regular and quickly) or to use a second RTL-SDR -- you might want that for the option to use different antennas (no 433/137 dual bands IIRC) anyway.

But I guess your parsing script to start and stop rtl_433 with event counting and timeouts is really the best way to have that degree of control.

Yes, I tried running for a fixed time, but parsing got messy, so I now -E quit after the first packet, parse it and return until I collect a sensible set of temp & humidity to pass on to grafana. There are several LaCrosse stations around me so I have to check the ID is mine as others are getting spurious readings (maybe in the sun).

Oh, and they are triggered from cron once an hour, so not running the receiver all the time saves heating the stick and wasting energy ( a little bit, maybe)
