I installed a few 2450 IOLINCs ( 1 output relay/ 1 sense input)this weekend and they respond to standard insteon on/off commands for turning on or off the relay output.
The only thing left now is how to use the sense input. I basically need one function to poll the status of the input on or off and one function to create a trigger when there is a change of state on the input.
So far I linked the 2450 to group 1 on the powerlinc as a responder. From this point on I don't know what to do.
Does anyone have any ideas?

I don’t have an IOLinc but according to the Smarthome User Guide for the IOLinc the sensor is linked to other Insteon devices the same way any responder would be linked to a Controller. That means the IOLinc is sending Group commands to the Responder (PLM/PLC in your case) just as it would to a LampLinc or SwitchLinc. You should be able to define a trigger using Insteon Group In as the Trigger Type with a Trigger Value that matches the condition you want to be aware of (ON, OFF, Any) etc.
I did not see anything in the User Guide about querying the sensor status. You could try the standard 0x19 Status Request command and see what it returns when the sensor is On versus Off.

Ok so following up on your lead, I checked the incoming PLC queue every time the sense input changes state and here is what I get-->
When sense input is shorted to ground-->
Incoming Insteon received on Insteon DM controller INSTEON PLC. From Address:[0F.89.F0] To Address:[05.0C.0C] Flags:[69] Cmd1:[19] Cmd2:[1]. Decode: Group Cleanup. From: IO_GAS_HEAT To: POWERLINC1 Group: 1, Off
When sense input is open -->
Incoming Insteon received on Insteon DM controller INSTEON PLC. From Address:[0F.89.F0] To Address:[05.0C.0C] Flags:[69] Cmd1:[17] Cmd2:[1]. Decode: Group Cleanup. From: IO_GAS_HEAT To: POWERLINC1 Group: 1, On
I don't understand why it's decoded as a group cleanup, Can I still use Inteon Group In as a trigger? I tried it and it doesn't seem to work unless I am doing something wrong.

A Group message sequence is made up of two messages. First a Group Broadcast is sent with no specific To device address followed by a Group Cleanup Direct message to every responder that has been linked to the Controller. The PLC is known for not tracing every message that appears on the powerline. Also it is possible that the IOLinc is not sending the Group Broadcast message but I doubt that. I think the Insteon Group In will trigger from the Group Cleanup Direct as there is no guaranty a responder will actually see the Group Broadcast because there is no ACK and no retry associated with that Insteon message.
What did you code for Trigger values and did you save the Trigger before running the IOLinc test.

I tried the following-->
trigger type : insteon group in
trigger ID: IO_GAS_HEAT ( this is the 2450)
trigger ID NO : any
trigger value : ON (0x11)
I also tried trigger value : any
I see both group cleanups as pasted in the previous message but the trigger won't fire.
I saved and also re-initialized PH in case...

Sorry, I wish I had one to test to give you absolutes. All my Insteon Triggers are Insteon Group In but I also see the Group Broadcast messages. The next thing I would try is Insteon Device Chg with Any Any.
I changed one of my triggers from Insteon Group In to Insteon Device Chg and the trigger fires when I turn the switch on and off. Also confirm that the Boolean field in the trigger is 1

You might test using Insteon Device Chg, any, any, any and if you then see it you can filter in the Boolean.

What release of PH are you running? Even 2.1b does not have a device type for the IOLinc. What device type did you specify for the IOLinc.

I finally got it working with the Insteon Device Chg. Once I knew it could trigger I used the ON in the trigger value to filter an ON condition and that works too!
Thanks for the help...now I need to figure out if I can check the status with a poll. So far checking with a standard status request returns the conditon of the output relay and not the input sense.
Does the responder (PLC) remember the last condition coming from the controller? Maybe that is a way. Another way would be to link the 2450 to a virtual device or some switch in the house that I do not use to control a load and set it as a responder. Finally I can always set a global variable, but if PH somehow misses the event it's not failsafe.
It needs to be failsafe because I am using the IO to sense if my HVAC has switched from heat pump to natural gas in a dual fuel system.
I'll post if I get to figure it out .... in the meantime if anyone has any ideas for me to try..

I am using it set as a switchlinc relay device for lack of a proper device type.

Neither the PLC nor PLM keep track of individual device status. There may be a command that returns the state of the Input (sensor). The IOLinc looks similar to the SimpleHomeNet EZIOxx devices which have been around much longer and they do have a command that returns the state of the Inputs. Not likely Smarthome would document such a command (if it exists) to the general public. Could be in the Developer SDK documentation but that is a $200 expense that may not have any useful information.

A post on the Smarthome forum provides the answer to the query of sensor status. Issue cmd1 0x19 cmd2 0x01, returns the on/off state of the sensor.

Thanks Lee
Tried it as soon as I got home today and it works like a charm. I was getting so desperate yesterday that I was using an unused button on a KPL to store the state of the sensor...now this is much more elegant...
