add analog ports #69

Closed gekkekoe closed 3 months ago

vekexasia commented 3 months ago

Hey @gekkekoe what are analog ports?

gekkekoe commented 3 months ago

it's the output of the co2 sensors for example. They output 0v-10v. https://www.zehnder.nl/nl/ventilatie/co2-gestuurde-ventilatie/zehnder-co2-room-sensor-0-10v

Ooh that's new. I never saw those. Wondering if there are other sensors available. Do you have other examples? Btw thanks for PR .

I have the option box, which exposes those 4 0-10V inputs. I have a 0-10V zigbee dimmer attached to the first 0-10V input. image

I don't have anything attached to the 2nd port, but it's showing 25.5V, which shouldn't be possible...

When I change the output on the zigbee dimmer, I see some strange values coming by on the comfoair-esp32, like 1846.9 V.

Is it only the intention to read these 0-10V values, or will we be able to change them --> act like a CO2 sensor, etc?

I also have an option box with 2 co2 sensors attached. I only see NA on port 3 and 4. I also tested one of the sensors, and when it's ramping up, I do see weird values (1894.7 and -1711.2). When it's stable, I see the 0v-10v. Can't remember if I saw this with the mqtt implementation (only patched the mqtt version locally).

Did some digging, and it was bug. Had to read UINT8 instead of UINT16. Made a new pull request.
