Controlling the power regulator with the ESP32 - what to replace the buttons with?

Question

Dear forumers.
I have such a power regulator:

.
I would like to control this via ESP32.
What to replace the buttons with?
Transistor? optocoupler? SSR? Due to the switching speed, a standard mechanical relay is not an option.
Best regards

. With other buttons, or let the faster hand press them. If you have 'manual control' with buttons in your existing configuration, nothing else will speed up the process.... You would need to redesign the machine for automatic control, then you can replace the control buttons with whatever you want according to the process. e marcus

A response of the type: I will write something there and "accept 2 points". Nothing comes of it.
Replace button, with button?
Nobody writes about acceleration. Instead, it is written that the ESP is to be controlled, and due to the clicking every, say, few seconds, a mechanical relay is out.

Read again, or 2x your question! Buttons are the control/input side of the device, the side where you enter tasks, process data, commands , information from sensors etc. ( otherwise INPUT). Other peripherals such as relays, transistors, indicators or other actuators will be on the OUTPUT side. So what do you want to change? What function do you want to replace and what purpose do you want to achieve with this change? Are you sure you know what you want? e marcus

I suppose, he wants to be the winner in the conversation. You know, such times, the lack of logic wrapped up in so-called assertiveness, courses, training, those climates ....

You already have the executive member (triac, optotriac and simple transformerless power supply). If there is to be an ESP32, what's the problem of doing all the handling on it? The original power supply will be too weak for the ESP though.

There are two options:
1. build an interface between the ESP and the existing regulator - optocouplers would make sense (power separation), it would be a good idea to reverse engineer the existing regulator from the pushbutton side and see how it is done by the majfrids
2. add an actuator to the ESP and omit the existing regulator - google ESP+phase regulator (depends on what you want to control).

The buttons are wired sequentially:
Down>R8>IO13 of this IC without inscription
ON/OFF>R15>IO2
UP>R7>IO12
Based on other solutions of this type, I suspect this is something like a digital potentiometer.
When connected to 230V there is +1.2V DC and GND on the buttons

.
By design, this is intended to be an interface to the so-called "zero export". The ESP is supposed to poll the EE meter and, in the event of energy export to the grid, is supposed to regulate, say, the power of a heater or something similar.

ArturAVS · Answer

This is what I suspected. A digital potentiometer makes no sense in such an application, here it is either PWM or phase control (although the optotriac is out of sync with the mains and you can't see the zero crossing detector circuit) or even group control if it is only for heaters. Write the whole operation on an ESP and add phase/group control, on the tape you probably have signals, Vcc, GND, output and zero detection. In truth, it's better to redesign the whole thing from scratch.

karwo · Answer

. That is, the keyboard - 3 buttons are wired to the ADC input of the controller. Again @ArthurAVS is right - better to do it from scratch on ESP, just would need to consider what type of phase/group control would be more beneficial to use.
