What are you using as a dew heater? I'm looking for one, usb, single strap and obviously 100% Indi controlled.

I am working on a version based on arduino nano and USB_Dewpoint INDI driver. for my purpose i use only one channel linked to other two

This one has what you are looking for: www.usb-foc.us/shop/product/new-usb-dewpoint-v3-11
INDI driver: indilib.org/aux/usb-dew-point.html
Or you can build your own and also develop drivers. I am currently testing this: github.com/ChrisV77/TelescopeDewHeaterController
It is based on Arduino and can be set to automatic or manual. Values are displayed on an OLED display. I have already build one, next step will be creation of INDI drivers a modification of Arduino code.

Mine is just using existing INDI driver, I need only to recheck all the things because i started it on January

Well, I didn't started development of the driver, I am not even a developer. So this could be the way, how to make it easier, just to modify existing Arduino code to provide the data which existing driver needs. Thanks for this info.

In my opinion the best way is to reuse all the things that already exists. I found a base code for the arduino, then I studied the USB_Dewpoint INDI driver and the commends that it sends out the the expected response. With these infos I adapted the arduino code to receive and respond to the serials commands with the values.

It can be use also as  is without usb connection. It starts in auto mode and it check the temp_amb against the dew poit plus a value and it adapts the pwn output from 0 to 100% when the temp_amb is near the dew point.

Hi, the code you modified is for this github.com/ChrisV77/TelescopeDewHeaterController ?

Thanks
