Creasol DomBus12 is a compact module, 40x30x11mm, with 9 configurable inputs/outputs.
It can be connected to the Domoticz controller by a RS485 serial bus (4 wires, 2 for 12/24V power supply, and 2 for data at 115200bps).

As other DomBus devices, DomBus12 is designed to consume low power, be reliable, fully configurable and easy to use. Each port is fully configurable, e.g. as analog or digital input, twinbutton (double button), counter, buzzer,  NTC 10k, ... 2 ports may be used as open-drain output, to activate 2 external relays or LEDs.

DomBus32 is a DIN-RAIL module, 54mm wide, with 3 relay outputs, 3 AC inputs and 5 low-voltage I/Os.
AVAILABLE IN TWO VERSIONS: DomBus protocol and Modbus protocol!

DIN-rail high reliability and low power home automation module with relays output, low voltage inputs, one 100-250Vac input and plugin terminal blocks.Works with home automation systems like Domoticz, Home Assistant, Node-RED, OpenHAB and more...

Can be used to manage alarm sensors, pushbuttons, lights and other loads, and monitor 230V presence (detecting power outage).

Home automation module that can be used as a stand-alone single or dual axis solar tracker, working autonomously.

Can also be controlled by a home automation system, like Domoticz (using DomBus firmware + Domoticz plugin), Home Assistant, Node-RED, OpenHAB, ioBroker and other systems supporting MQTT protocol using DomBus firmware + DomBusGateway (a python software performing DomBus2MQTT bridge), or custom applications and other sustems supporting the Modbus protocol (using DomBusTracker2 version with Modbus firmware).

Reliable low-power domotic module designed to enable/disable loads, saving energy consumption, zeroing the standby power.

DomBus33 is a DIN-RAIL module, 54mm wide, designed to control an existing lighting system with 3 lights using 115/230V pushbuttons and stepper relays.

Creasol DomBusEVSE  is a full features, fully tested and CE certified DIN rail module, designed for Domoticz and Home Assistant, but working even with OpenHAB, Node-RED, ioBroker and other home automation systems, to  charge electric vehicles using the standard SAE 1772 and IEC 62196-2  Mode3  (AC charge, up to 22kW power).

It works as  stand-alone  (with or without any domotic controller: in this case the charging current is controlled by the EVSE module) or in  managed mode   (the charging current is set by a domotic controller / automation, so in this case the EVSE works in "stupid mode").

ESP8266 is a very powerful and cheap MCU equipped with WiFi transceiver, very useful to expand inputs/outputs of a domotic system.

Creasol DomESP1 board is designed for ESP8266 module NodeMCU V3, with 900 mils header pitch (optionally, soldering additional headers, it's possible to use the 1100mils module or WeMos D1 mini module), and integrates the whole circuitry to manage digital inputs, one analog input, 4 relay outputs, I2C bus, 1wire bus and 2 mosfet outputs with 8A 30Vmax capability.

Creasol DomBus23 is a module for home automation system with several different kind of configurable inputs/outputs in a short size:  74x72x24mm.

Creasol DomBus36 is a din-rail relay industrial-grade module for building automations and home automation systems, 115x90x40mm, with 12 relays outputs, SPST (Normally Open outputs) with 250V 5A max capability, divided in 3 groups of 4 relays, each group with a 5-position screw terminal blocks: 1 common + 4 outputs

Creasol DomBusTH is a fully configurable small electronic board, 32x17mm, that can fit any blank cover with a 3.5mm hole in the centre, needed by the thermal/humidity sensor to exchange air with the room and to get the 3 LEDs light out. It can be connected to a Domoticz controller using the DomBus protocol, and other contollers (Node-RED, HomeAssistant, OpenHAB, ...) using the standard Modbus protocol by RS485 serial bus (using a standard alarm cable with 4 wires, 2 for 12/24V power supply, and 2 for data at 115200bps). Available in both DomBus and Modbus protocols

Creasol DomRelay2 is a compact module, 43x24x25mm, within 2 relays with 12V 200mW coil, 250V 5A SPST contact with special material designed to prevent contact welding due to excessively high surge current load (capacitive loads or tungsten lamps).

Contacts are protected from overvoltage by metal oxide varistors; coils are protected from overvoltage by free-wheeling diodes.

Relay coil should be driven at 12Vdc 17mA: using DomBusTH or DomBus12 modules it's possible to drive relays using a lower power system, consuming less than 1/4 of nominal power.

AVAILABLE IN TWO VERSIONS: DomBus protocol and Modbus protocol!
Creasol DomBus31 is a din-rail relay module, 115x90x40mm, with 8 relays outputs. 6 relays are SPST (Normally Open outputs) with 250V 5A max capability, and 2 relays are SPDT (both Normally Open and Normally Closed outputs) with 10A capability. High efficiency module, with very low power consumption, only 600mW with all relays ON.

DIN-rail domotic module, 115x90x40mm, supporting both DomBus and Modbus RTU protocols, that integrates 12x low voltage analog/digital inputs, 3x relays outputs, 3x 115Vac / 230Vac inputs. Optionally it is able to control and monitor the power supply fed to a burglar alarm external siren.

Suitable to interface alarm sensors (magnetic contact sensors, PIRs, tampers), monitor power outage (by the 3 AC inputs) and control up to 3 outputs (relays).

Home automation module that can be used as a stand-alone single or dual axis solar tracker, working autonomously.

Can also be controlled by a home automation system, like Domoticz (using DomBus firmware + Domoticz plugin), Home Assistant, Node-RED, OpenHAB, ioBroker using DomBus firmware + DomBusGateway (DomBus2MQTT bridge) or Modbus firmware.
