Could you upload your code please?
For the GIF shown above, I only built a microcontroller with ESPHome on a phase angle dimmer. With the light function I could control the phase angle (=power). I haven’t had time for automation yet. My plan is for the future when I have replaced my heating rods with a heat pump. To control the power of the heat pump with the pwm signal of the microcontroller.
Just re-found my post here - but my question still remains: is it possible to achieve efficient (i.e. proportional) use of solar surplus with a simple on-off pulsing switch? I still don’t think so - some kind of phase-angle device must be needed at the hardware level for the utility meter to not “see” any positive import pulses?
