HAOS on an x86-64 NUC with 1-wire through local USB?

Installation Home Assistant OS
1

we have been running our house on home-built python for the last ten years or so, but want to move to Home Assistant - nicer features, and all those extra dev hours.

I am hoping to install HAOS on to the Intel NUC that I am currently using to run the house, but my only concern is 1-wire. our 1-wire sensors for the various thermal stuff (solar, stove, valves etc.) are connected to a DS2490R USB 1-wire bridge physically connected to the home automation PC.

in my beta/test HASS deployment (on a VM), I looped into the owserver on the existing HA PC, but clearly, that won’t be there.

The documentation looks unclear - does HAOS support USB connected 1-wire? The integration seems to only support owserver, and it’s not clear that owfs can be installed on the HAOS itself… I see plenty of mentions of an R-Pi, but that’s more GPIO - not a thing on the NUC.

I can’t see a (non destructive) way to test this myself, so looking for advice. is anyone else doing this?

I have very similar problems - did you get some answers? If I try to install the 1-wire integration, it asks me for the server and port. The server and port of what? If this refers to OWFS, how do I install OWFS? I don’t want to have to run another RPi just for this. Does the integration work with the DS2490R, or with a 1-wire to I2C adapter, or with the 1-wire connected to a GPIO or what?

Thank you - Rowan

Have you looked at using ESPHome to connect your 1-Wire devices to Home Assistant? Simply add an inexpensive ESP8266 or ESP32 microcontroller running ESPHome in place of your DS2490R. ESPHome can be added to HA as an AddOn.
