Questions such as ‘Does device X work with gateway Z?’ are a daily occurrence. The short answer is, any Z-Wave device is meant to be interoperable with any other. There is a group of people who check this and issue license numbers based on a device’s ability to fit in with the Z-Wave standard. The longer answer is, some gateways and networks don’t like 3rd-party devices. Alarm companies may want to corner the market on selling only their devices, a security firm may not allow any other device to reside on its network for security reasons, or there may just be severe limitations in the ability of an older device to keep up with faster devices. But in general, any device should work with any other. When in doubt go to your alarm company. You’re not revealing any secrets, and some providers may even help you (check their websites too).
