Denkovi Assembly Electronics ltd.

Standalone SNMP and Web based internet/ethernet module (IP controller). It is suitable for home automation, data acquisition, relays controlling, sensors monitoring, fire alarm systems and so on. It has 24 digital/analog I/O. Supported by DRMv3 software. Works with Home Assistant, Domoticz and OpenHAB home automation systems as well as with Node-RED IoT platform. It is possible to be controlled by: configuration software, command line, Android/iOS app, web browser, HTTP API commands

A general purpose 12 SPDT channel relay board (power supply 5VDC) for switching high-current electrical loads (both AC and DC) siuch as motors, lights, pumps, contactors and more.  With this relay board, any logic-level signal from 3V up to 30V can be used to activate a relay (it may be controlled direclty by microcontroller TTL logic as well). It can be used successfully for example with PIC,AVR,ARM microcontroller, Raspberry PI, Arduino outputs and other.

This device is an Ethernet and Web enabled input module suitable for home automation, environment monitoriong applications, logging/counting different events and many others. SmartDEN IP-32IN provides 16 digital inputs (for motion detector sensors, dry contacts, switches, buttons), 8 analog inputs (for temperature, humidity, light, pressure sensors) and 8 temperature inputs designed for NTC thermistors type B57500M. The integrated web server for set-up, SNMPv2c and HTTP/XML allow easy embedding in other systems. Interesting feature of the module is the ability to control remote relays based on input event or work in "Data Logging Mode" in order to post data in xml format on a remote server. Supported by DRMv3 Software. Various software examples are provided and the module is supported by our android and ios apps. Works with Home Assistant, Domoticz and OpenHAB home automation systems as well as with Node-RED IoT platform.

This is USB Relay Module with ModBus RTU protocol support and 16 relays (the type is selectable during purchase). The relays are controlled via PC USB port and it is shown as virtual serial port (virtual com port). It is possible to control directly 220V / 120V devices with your PC usb port up to 15A max. The module supports up to 16 independent timers with min. resolution 100ms. Supported by DRMv3 Software. Works with Home Assistant, OpenHAB home automation systems. There are lot of profesional ModBus software apps for this usb relay board allowing to be easily integrated in any ModBus automation project. Software examples are available as well. This is the DIN RAIL BOX version.

A general purpose 16 SPDT channel relay board (power supply 5VDC) for switching high-current electrical loads (both AC and DC) siuch as motors, lights, pumps, contactors and more.  With this relay board, any logic-level signal from 3V up to 30V can be used to activate a relay (it may be controlled direclty by microcontroller TTL logic as well). It can be used successfully for example with PIC,AVR,ARM microcontroller, Raspberry PI, Arduino outputs and other.

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 Home Assistant, Domoticz, Openhab and Node-RED) and lot of software examples.
