Lesson 13 Automation 2.0, Lesson 13, creating a trigger for a WHEN section with controlled polling time
Good afternoon. Let’s start the topic.
Today’s topic will include the following components of the control system:
- relay T2 (boiler control);
- radiator thermostat (E1,W600), room √1 and √2;
- virtual switches (lesson 12);
Part 1. Preparing the T2 relay.
To control the boiler, we use dry contacts of the T2 relay. These settings are described in my topic, figure “C” ( Rele T2, let's talk about it again )
I also suggest connecting dry contacts to the boiler in the following way. This connection gives us the opportunity to quickly disconnect the heating boiler from the automation system at any time. I call this mode emergency. At any time you can block the automation by turning off 1 channel (L1) T2. The second channel will be involved in the automation (L2).

Part 2. Creating the “On” “Off” scenario of the TVR thermostat.
To save the TVR battery charge, we will create scenes for starting and stopping the heating of radiators (low temperature/high temperature).
Room √1, √2 “On”, “Off”

Part 3. Creating automation for heating the room at 20°C, stopping at 21°C.
When creating automation, we use the virtual switch lesson ( Automation 2.0, lesson 12, blitz topic, VIRTUAL Aqara switch )
Fig.7,8,9,10,11
Part 4. Creating boiler control commands using the T2 relay (dry contacts).
Since contact 1 (L1) is constantly closed and plays the role of “manual boiler shutdown”, we will use contact 2 (L2) for control.
We create the “On” boiler automation.
Fig. 12
We create the “Off” boiler automation.
Fig.13.
This automation is given as an example. You can decipher the rooms and make time periods of the temperature regime. I described this in previous lessons.
This will end this lesson.
Thank you for reading and sharing the topic (you can also share it on other platforms with a link to our forum).
More to come.
