Hi again
i have been running a seperate psu on the sensors ever sinces suggested and so far so god :D
I will find a i2c device in my box of "nice to have stuff" to see if its stable with that, because i need some extra io´s and to my knowlegde the easiest way is a i2c expander??

thanx for the ...

Yes i have seen a lot of i2c problems on the interweb.
I did consider putting on a i2c io expander and a RTC also on i2c.
I might end up using a thrusty old arduino mega and only use the esp32 as a wifi module.
Some projects as my current one requires reliability.

Hi i am not using parasitic power, but they are powered by the same esp pin. I will try to power from external power.
When it goes blank means virtuino goes blank (out of range maybe), but the esp is reading it as a lower value... all my heating circuits went full open at the time.

I will try the ...

Hi
I am making my own Centralheating controller and so far everything is starting to play well together and i am starting to finetune it.
Main control is a ESP32 WROOM and my problem is a sensor bus wire to 12 DS18B20 temperature sensors.
Its working perfect for a day or two, then ALL sensors goes ...
