Jay,Thanks so much for your prompt reply. I appreciate you responding to my query about Indigo V6, even though it's not officially supported any more. I'm sure you and the team are busy adding lots of new goodness to Version 7.
For others wanting to use the sensor input on an Insteon 2450 I/O module with Indigo Lite:There is a way
This Insteon module can be configured as an X-10 device, and will then integrate with V6 Lite.
Here's how.
• If you've previously added the 2450 as an Insteon device in Indigo (as I had), delete it.
• Add a new X10 device to your Indigo set-up. I chose "Generic Light Switch" as device type. Assign it an unused X-10 code.
• For good measure, reset the 2450 back to factory defaults. I don't know if this is necessary, but it seemed like a good idea.
- unplug module from power receptacle, wait 10 seconds, press/hold the Set button, and plug it back it. Release the Set button after three seconds.
• Program the 2450 with an X-10 address:
- Press/hold the Set button until the 2450 beeps. This puts it into linking mode. The LED will start blinking.
- Tap the Set button. The LED will continue blinking.
- send the desired X-10 address + ON three times. You can do this on the Indigo DEVICES page: click TURN ON for the new X-10 device you entered above three times. If you observe the Indigo log, you'll see it sending an X-10 ON command addressed to the that newly-added device code.
- the LED will stop blinking, indicating that the 2450 has detected the three successive X-10 commands, which magically assign it the X-10 device code.
That's it. The 2450 is now configured as an X-10 device with the specified code, and can be used as an input to triggers in Indigo. When the sensor attached to the 2450 closes, the module sends an X-10 ON code. When the sensor opens, it sends an X-10 OFF code.
Full instructions on programming the 2450 as an X-10 device are found here:
