1-wire DS1820B sensor names do not persist after REM restart

[dkossman]

Not a major issue but...

1. add the 1-wire interface to REM
2. go to the 1-wire device list
3. name each DS18B20 device and save it
4. save settings on main panel
5. note that probe names are listed on the 1-wire device list
6. restart REM

Expected: 1-wire device names persist and are shown in the 1-wire device list

Actual: names on the 1-wire device list revert to the original hex names (e.g. 28-00000583ae1e0, though if you inspect each device, the name you set is there, and if you click save, re-appears in the device list

I posted a fix for this.

@rstrouse thanks for the fix - sorry for the delay. my Pi's SD card died, I finally replaced it and started over. I pulled the latest REM, NJSPC and Dashpanel to my Pi 4b. running latest Raspberry Pi OS.

However, now when I add my 1-wire bus to REM, none of my DS18B20 temp probes are detected, though I know they are there and working (i can read them with my own server code and see them listed in the w1_bus_master directory. Can't add them manually either. what seems a bit odd is that i don't have the SPI interfaces enabled, but i see them being initialized and I don't see the 1-wire bus being initialized (and yes, i set it to Active when i added it).

Any idea what is going on? Info log below following a reset and then running 1-wire bus scan:

never mind, figured it out, need to run REM as root. odd because i can read the 1-wire probes fine in my own code and from the command line, running as user pi.
