help Universal Devices ISY-994i FAQ

Does the Universal Devices ISY-994i support Insteon and Z-Wave at the same time?

Yes, but Z-Wave requires the appropriate ISY-994i hardware, module, and dongle, while Insteon normally requires an Insteon PLM. Universal Devices documented using a Z-Wave lamp in a scene with Insteon devices, which is a key strength of the controller.

What can the IR version of the ISY-994i control?

IR models can receive commands from an RC5-compatible infrared remote and use those commands to trigger ISY programs. Check whether the unit is marked IR or IR PRO, because standard and IR models do not have identical hardware.

Is the ISY-994i still sold, or should I migrate to eisy?

Universal Devices announced that the ISY994i series was discontinued after about 14 years and that most units could no longer receive new modules from June 1, 2023. The company points owners toward Polisy or eisy, so a used ISY-994i is a legacy purchase.

Do I need a separate Insteon PLM for the ISY-994i?

Yes, an Insteon PLM is needed for Insteon and X10 communication because it connects the controller to power-line devices. A Z-Wave-only setup can avoid the PLM, but that does not preserve an existing Insteon network.
