Hello everyone,
I have an electrical heater in my hot water tank that I can control between 45W and 3.2kW via PWM.
I do this with an M5stack PWM module (Atom light platform), which technically works perfectly.
I use the following YAML code for this:
output:
- platform: ledc
pin: GPIO22
id: gpio_22
frequency: "400Hz
light:
- platform: monochromatic
gamma_correct: 0
output: gpio_22
name: "Heater_Boiler_Power_Setpoint"
My problem: I can only adjust the power between 10% and 90%, the heating rod then starts at just under 50W, which is about 35W/% over the whole spanā¦
My goal is to regulate the power in much smaller steps.
Question(s):
- Can I also transmit bit values from Home Assistant instead of %?
- In the next step, I would like to regulate the power automatically (availability of PV power), perhaps via a thermostat?
Iām pretty much at a loss at the moment, maybe someone here has an idea?
Thanks and best regards
