AIO pins 0-5v reading 3.150v - Honeybadger - 04-24-2025
I’m injecting 5v on the pins AI1-8 and they are supposed to read 0-5v but in Home Assistant they read 3.150v
I used the pin 5v from the board to test it too, only reads 3.150v
RE: AIO pins 0-5v reading 3.150v - admin - 04-24-2025
what voltage value showed in KCS monitor webpage?

How do I access that page after the system is all configured and installed into home assistant?
I have the AIO connected to the router via ethernet cable.

do you want download KCS firmware or firmware by ESPHome yaml?

I don't know how to access the KCS monitor page, can you guide me?
The board is installed on Home Assistant using the ESPHome yaml file provided by you.
I have attached here my YAML file.

which channel you have connected with analog signal, you can take a photo how you wire, we can test as your photo.

Pictures attached here.
I'm basically connecting the 5v from the AIO directly into the AI-03 to test the 5v readings from Home Assistant but I'm getting 3.150v instead of 5v.

try to replace this pin:36 code with new code:
- platform: adc
pin: 36
id: adc36
update_interval: never
attenuation: 11db
-----------------------------to new----------
- platform: adc
pin: 36
id: adc36
name: "A32 Pro A1 Voltage"
update_interval: never
attenuation: 11db
filters:
- lambda:
if (x >= 3.11) {
return x * 1.60256;
} else if (x <= 0.15) {
return 0;
} else {
return x * 1.51;
}
Code:
- platform: adc
pin: 36
id: adc36
name: "A32 Pro A1 Voltage"
update_interval: never
attenuation: 11db

After this update the sensor is not reading anything.
RE: AIO pins 0-5v reading 3.150v - Honeybadger - 04-25-2025
Is the ADC sensor good enough for millivolt readings?
Are the sensors reading 0-5v or something else and then transforming it with calculations?
