smartDEN Opener - IoT smart Garrage Door Controller with Wi-Fi, Relays, I/O, MQTT, HTTP

smartDEN Opener is a relay controller which provides motor control for garage doors, barriers, awnings, windows, blinds, roulette shutters. It can be opened/closed via RF 433 MHz pocket remotes but also provides Wi-Fi wireless interface for control from mobile smartphone, tablet or computer.

The android app DAE-aModules (iOS app support is comming soon) ensure secure communication with the controller, easy monitoring of the extra relays/sensors, receiving event notifications (for example when and who opened the door lastly) and even control the door via GPS location (for example when approaching your garage door driving your car).

The controller has and several additional I/O lines for extra buttons, switches, contact or barrier detectors, anti-freezing temperature (or other) sensors and two extra relays for warning lamps, heaters or door locks. An email can be sent to one user email address upon triggered event and the internal memory keeps small amount of log records for the previous 300 events.

For system integrators we provide two communication protocols (MQTT and HTTP/XML/JSON) for embedding in third party systems (such as home automation servers like Domoticz, Openhab and Node-RED) and lot of software examples.
