Creasol DomBus modules

Our industrial and home automation modules are designed to be

• very low power (around 10mW with relays OFF)
• reliable (no disconnections)
• bus connected (no radiofrequency interference, no battery to replace).

Modules are available in two version:

1. with DomBus proprietary protocol, working with Domoticz only
2. with Modbus standard protocol, working with Home Assistant, OpenHAB, Node-RED

DomBusEVSE - EVSE module to build a Smart Wallbox / EV charging station

Complete solution to make a Smart EVSE, charging the electric vehicle using only energy from renewable source (photovoltaic, wind, ...), or adding 25-50-75-100% of available power from the grid.

• Single-phase and three-phases, up to 36A (8kW or 22kW)
• Needs external contactor, RCCB (protection) and EV cable
• Optional power meter to measure charging power, energy, voltage and power factor
• Optional power meter to measure the power usage from the grid (not needed if already exists)
• Two max grid power thresholds can be programmed: for example, in Italy who have 6kW contractual power can drain from the grid Max (6* 1.27)=7.6kW for max 90 minutes followed by (6* 1.1)=6.6kW for another 90 minutes. The module can use ALL available power when programmed to charge at 100%.
• Works without the domotic controller (stand-alone mode), and can also work with charging current set by the domotic controller (managed mode)

DomBusTH - Compact board to be placed on a blank cover, with temperature and humidity sensor and RGW LEDs

Compact board, 32x17mm, to be installed on blank cover with a 4mm hole in the middle, to exchange air for the relative humidity sensor. It can be installed in every room to monitor temperature and humidity, check alarm sensors, control blind motor UP/DOWN, send notifications (using red and green leds) and activate white led in case of power outage.

Includes:

• temperature and relative humidity sensor
• red, green and white LEDs
• 4 I/Os configurable as analog or digital inputs, pushbuttons, counters (water, gas, S0 energy, ...), NTC temperature and ultrasonic distance sensors
• 2 ports are configured by default as open-drain output and can drive up to 200mA led strip (with dimming function) or can be connected to the external module DomRelay2 to control 2 relays; they can also be configured as analog/digital inputs, pushbuttons and distance sensors.

DomBus12 - Compact domotic module with 9 I/Os
