Hello,

I follow the tutorial in youtube and mervis IDE doesn't dectect the sensor even if I put the UNIPI to commisioning mode.

Thank you in advance.

Can you provide more info? Is the sensor connected directly to UniPi? Have you compiled and deployed the project with the 1wire bus to the UniPi...?

Yes, around 04:00 min time: https://www.youtube.com/watch?v=I3AFm-TVSt4 and also in the documentation in pdf at http://downloads.unipi.technology

Yes I did exactly what it did for the 1Wire in the video but after the commisioning it said "Selected channel doesn't exists in PLC" so doesn't detect the sensor.

Sorry there is a small bug in the video. You need to build the project and deploy it to UniPi before you can attach the sensors....

To be able to build and deploy the project to the UniPi you have to fix all the errors. The video has been updated so see that https://www.youtube.com/watch?v=PymuUoXXqGQ

If you are having troubles, download the default project from the examples archive at http://downloads.unipi.technology

Tomaš, a question regarding this Sensor topic: I need to integrate three 1Wire DS18B20 sensors in Mervis. I did follow the tutorial and did add three devices to the 1Wire channel instead only one device like in the tutorial. But after plugin the sensors I see only the parameters for one sensor in Mervis (I did boot the Raspi with a different image containing Evok for verfication, Evok shows all three sensors correctly).
Should I configure 1Wire devices in Mervis one after another?

Best regards,
Matthias

...and is there a documentation for the default function blocks in Mervis?

Hello Mathias, did you use assign sensor or detect sensor? If you have the UniPi in commisiong mode you can also use detect sensor on the 1Wire bus from where you should see all three sensors on the bus and if you select it, it should be automatically added to the channel.

The documentation is in the About->Help (or press F1 on when the function block is selected).
