I installed evok on rpi4 with buster. One wire, websocket runs ok but I am unable to run the control panel due to nginx problems.

Any idea how to fix it without reinstalling evok?

Per room you may set: Program or manuell temperature setting, boost for 1 hour, set temperature, display valve status and get graphical temperature curve.

temperature sensors are shelly HT and in one room Netatmo

Node-Red on Raspi 4 works perfect - no problems at all

does unipi 1.1, Raspberry Pi 4, buster, newest evok, node-red work correctly?
I would like to ungrade my Pi to version 4 on my unipi 1.1.

I have 4 Temp sensors connected to an unipi 8 port hub. (Old model with 8 ports on one side). It works perfectly for about one week. Then, all of a sudden, evok is unable to reconnect to the one wire bus. After restarting evok the problem still exists. When I disconnect the hub from my unipi1.1 and connect it again and then restart evok, it again connects to the one wire bus and runs for about one week. Any idea what causes the the reconnect problem?

Hi Martin, still waiting for a response. Are you not supporting node-Red?

the slow version works ok
