Smart Relay support FAQ
Common questions about manuals, registration, and support for this brand.
-
How do I install a smart relay switch without a neutral wire?
Some smart relays are designed specifically for no-neutral setups (such as specific Zigbee or Sub-1 GHz modules). Always turn off the main circuit breaker before installation and strictly follow the wiring diagram provided in the device's user manual.
-
What does 'dry contact' mean on a smart relay?
Dry contact means that the relay's switch terminals are electrically isolated from the main voltage supply. This allows the relay to act as a potential-free contact for external low-voltage circuits or completely separate systems like garage doors.
-
Are smart relays compatible with Amazon Alexa or Google Home?
Yes, most Wi-Fi and Zigbee smart relays are designed to be compatible with popular voice assistants such as Amazon Alexa, Google Home, and Apple HomeKit, either directly or via an associated smart home hub.
-
Where can I find the user manual for my specific smart relay model?
Search for your exact model number (usually printed on the casing of the relay) on our platform. Since many smart relays are produced under various generic brand names, the model number or protocol (e.g., Zigbee 3.0, Wi-Fi) is the best way to locate the correct documentation.
