I have an application where I need to provide a "Contact Closure" or low voltage Input to the ISY-99 when there is no power in the house or the power is unstable. This assumes, naturally, that the ISY-99 is connected to an UPS.
Given the above, the I/O Linc is NOT an option.
The "TriggerLinc INSTEON Wireless Open/Close Sensor" is not an option either because the (Dual Band) Insteon PowerLinc Modem would not have power.
Connecting the Insteon PowerLinc Modem to a UPS doesnt work either because Insteon signals do NOT travel well THRU the UPS and the whole Insteon network becomes unreliable.
I can think of the following options:
1) Send Infrared signals to the ISY-99. I have no idea of how to do that, based on a contact closure or low voltage input.
2) Use an Arduino to send a REST command via Ethernet to the ISY to change a variable.
3) Use a CAI WebControl to send a REST command via Ethernet to the ISY to change a variable.
Does anybody have a view or suggestion?
Many thanks!
