Domoticz is a very easy and powerful controller for domotic systems, accessible by web browser and android/iOS app.
Raspberry is a single board mini computer, low power (less than 10 watt), with quad-core ARM processor, suitable for home automation.
DomBus1 is a device that can be placed into wall junction box to control lights, pumps, valves, and read inputs like door/window/blind magnetic sensors (for alarm), PIRs (for alarm and presence), door bell button, .... It's connected to Raspberry controller by a thin cable within 4 wires (for alarm, or better for RS485): 2 wires for data (RS485 at 115200bps, that permits to cover up to 1km), 2 wires for 12V power supply (better if battery backupped)
DomBusTH is a small board that can be placed on a blank cover and is designed to measure temperature and relative humidity. Also, it has 3 leds, white + red + green, that can be activated to notify a status or in case of power outage (like emergency lamp). Finally, it has 4 configurable I/Os (that can be connected to switches and pushbuttons, alarm sensors , buzzer, ...) and 2 open-collector outputs (suitable to drive external 12V relays).
The RS485 solution permits to:
avoid RF pollution (caused by WiFi and other wireless systems)
use a thin cable to interconnect all devices via bus
supply all devices by a battery backupped 12V power supply, so the home automation system will works even in case of blackout
Also, this system is optimized for low power consumption:
Raspberry consumes less than 10 watt
DomBus1 consumes 0.050W in standby and 0.3W when all 2 relays are ON. Just to compare, Sonoff Dual R2 consumes 1.2W in standby and more than 2W with only 2 relays ON.
DomBusTH consumes 0.03W
and is really plug&play: just connect a new DomBus device to the bus, and you can find in the Domoticz Switches Panel that device: change its hardware address from the switch panel to assign a unique address, and all inputs/outputs/sensors will be automatically available in Domoticz automatically.
What can you do with Domoticz?
Control indoor and outdoor lights
Make a reliable and full-feature alarm system, that shows status on the phone (Telegram app) and send pictures/videos in case of any event you want.
Send a picture on smartphone when someone ring the bell
Control the gate and pedestrian gate, to open them remotely
Measure room temperature and relative humidity
Control the heat pump or other heater/cooler: no need for thermostat in every room, but just a invisible thermal sensor in every room
During the winter, activates electric heaters if solar photovoltaic produce more power than usage power
If heat pump and solar photovoltaic are installed, optimize the power consumption by regulating the heat pump on the available power from solar PV
If ventilation system is installed, regulates it controlling the humidity of the rooms, and activating the dehumidifier (and cooling coil, if available) during the summer when solar power is available
Activate external devices like dehumidifiers, electric heaters, when there is extra power from photovoltaic, or when room humidity/temperature are not good.
Check the level of rainwater tank and control a valve/pump for watering the garden
Connect to a meteo station and grab data of rain, wind, temperature, humidity, pressure, in nice graphs

The following video shows a presentation of some domotic modules designed and produced in Italy by Creasol to make a reliable, easy and power-optimized home automation system.
The next video shows our Smart EVSE module that can be used to charge the electric car by using only solar power, or adding 25/50/75/100% of available power from the electrical grid.
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:
with DomBus proprietary protocol, working with Domoticz only
For our products we can offer FULL SUPPORT and CUSTOMIZATION: please contact us by Email or Telegram

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%.
