It works!

I'm using dlink.py to send dch-s150 motion updates to node-red through the python exec node.

python3 -u /home/pi/dlink.py ip pin loop

Exec node is triggered in spawn mode so it sends continuous output from python as a payload. Do what you want with the output. I use it to trigger occupancy for thermostat control with suitable timers, etc.

It actually makes the Dlink motion sensor useful without the cloud service. No lag.

It does use a fair amount of cpu to loop the python app though. There could be a better way.

However, thanks for your work on this. I think a lot of people would like to use their s150's directly. It's a nice piece of hardware.

Hello kskenyon,

I realize your post is a bit older, but I am trying to write a daemon that will poll these devices. Is there some doc (or do you have some info) about what is exchanged between these dch-s150 devices and a host?

thanks,

Ron

Something has changed, I run the script with a PIN and I get:

How do I fix the username/password problem? It seems like something has changed on the dlink end.
