Chandan,
Thanks for the reply. I have a ZM3102N Z-Wave Module out of an old Isis Hub (they discontinued 1st gen hubs). It says Alertme.com also. Don't know if it will work although I could match the 4 pins to the I/O easily. Funny thing now, the popup problem must be my RPi browser since I can log into HG using another computer on the same router at the RPi address and using that computer all is well with HG! I'll reinstall the RPi browser and that should work. I don't know what port to expect from controller and the Serial I/O. Have tried configs like 80, 8080, /dev/ttyS0, /devttyAMA0, etc. The HG Discovery looks like it works on anything but I can't add nodes. How do I check for a controller match to the RPi? What port config? What should Netstat (or another command) look like when I'm connected?
Thanks Much.... Jeff
