SmartWise 5V-32V relays are shipped without an external case because the main purpose of them is being integrated into another electronic device such as a gate opener.

But when used as a standalone relay, this protective case is a useful add-on to the relay. Both 5V-32V WiFi, 5V-32V WiFi+RF and 5V-32V Zigbee+RF versions of the relay are compatible with this box.

Note: SmartWise 2-gang relay's switch button on the relay board is short, so you will need a pin to push them for a manual on/off switch or pairing mode.
