Full automation of boiler room - what component to use - mmetal - 02-25-2023
Hello, this year i was finished installation of my new boiler room with 3 boilers, 16 pumps, 16 electric valves, one pellet burner... Now i need to make automation of all components. I was test some process with sonoff TH16 and 4CH pro devices and home assistant, only to see what exactly need and can to controll, and the main problem is that i need a lot of temperature sensors, pressure sensors, ultrasonic sensors, relays, contactors etc.
The best solution is to use home assistant, but if you have some suggestions, i am open
In text bellow i will try to explain what i plan to do, and it would be great that you suggest me components for my automation
- Measure temperature from -25 to 100 C on 42 places, and to have a possibility to controll devices (relays) by that temperature
- Measure water pressure in whole heating system on 10-12 places, and to controll electric valves for water and air accordingly measured pressure
- Measure water level in vertical expansion tank of 1200 lit, and controll electric valves for water.
- Measure level of pellet in pellet tank of 1800 kg (2000 mm height)
- Connect one smoke and fire sensor to controll fan in case of smoke
- Relay output on/off or no/nc for control pumps, burner, electric actuators, lights. Relay for pumps, burner, electric actuators will be controled by measured temperature. All relay outputs will controll electric contactor with 24vac coils.
I hope that you will understand what i need.
Please suggest me what componnent i should use.
If you need additional information, please contact me
Thanks in advance

if you have many sensors want to add to home assistant, suggest use KC868-COLB input module or KC868-AI.
KC868-COLB have 16 channel "digital input" and 16 channel "analog input" (dc 0-5v ) and 5 channel DS18B20 temperature sensor.
KC868-AI have 48 channel "digital input" .
so you just need to chose the sensor is dc 0-5v output signal type.
about relay board, there are many model can chosed. just suggest by ethernet way is stable.
