@juntiedt Problem solved!

Hallo,
I have installed EVOK on Raspian bullseye with no problems.
I am running node-red and there is one problem with EVOK.
websocket works ok and all http requests are working except http://localhost:8080/json/all.
Sometimes it works once after rebooting but then it looses connection to the server and node-red hangs up.
What causes this problem?
Any help appreciated!

is it possible to connect the 8-Relay Addon EMO-R8 to unipi light via the GPIO Connector and using evok?

I went back to buster. Now evok works ok!
Bullseye definitely needs some work.

I want to install evok on raspi with bullseye.
Does EVOK run on bullseye?
If so, can I use the EVOK version on github?

I cannot connect to the new SW image with user "unipi" and pw "unipi.technology"
I tried it with putty and directly connected to the Raspi

What is the problem?

one important thing at the end:
as soon as you apply a filter the received msg.payload from websocket comes in an array.
this means:
before the applied filter you could your device with msg.payload.dev
with applied filter you must read the device as msg.payload[0].dev !!!

I have solved the problem. Sorry for the quick post.
Attached please find the command flow for filter

I want to receive all devices via websocket except one wire sensors. How has the filter command to look like?
All devices but temp or temp and no other device.

I am using node-red with the websocket set command which works ok, but the filter command seems not to work.

Any help appreciated.

thanks for your information.

I have connected a 4 wire cable very close to the three wire sensor and connected the data line to 2 wires in order to use the hub. At the moment it works.

Hallo Unipi Team,
I am new to Modbus and now want to connect Extension xG18 to my unipi 1.1.
What is the evok interface to modbus?
How can I access modbus through evok?
Is there a connection cable coming with the Extension xG18 device?
The Extension xG18 will be about 5 to 6 meter away from my unipi 1.1.
Any info/help appreciated

I have a question regarding the above mentioned sensor, Does it come as a sensor with 4 wire cable (Data in + Data Out) in order to use it with Unipi HUb?

Hello Unipi Team,

I currently have 4 temp sensors from unipi which have 4 cables. Now I have got a one wire sensor (3 m) with only 3 cables (seems to be standard).
How do I connect this sensor with unipi 8 port hub (old model with all ports on one side). As far as I know, on your 4 cable sensors the data line goes to the sensor and then back to the hub on another pin of the RJ plug which the goes to the next port of the hub. This would mean, that I have to bridge somehow this two pins. Result seems to be an unstable bus.

Any idea how to connect 3 cable sensors professionally to your hub/bus?

this flow gets data from unipi 1.1. unipi lite does not have ai ao. Just skip it. temp input is one wire sensor data. the json all node initializes all variables and then websocket delivers actual data.

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
