Hi! I have bought a number of these relays: https://www.superbrightleds.com/mini-pir-motion-sensor-switch-with-built-in-timer-12-24-vdc-6-amps-mini-pir-switch?utm_campaign=200_tROAS-Pmax&utm_source=google&utm_medium=cpc&utm_term=&utm_content=N/A&gad_source=1&gclid=Cj0KCQiAlsy...

I had posted this in Python, but realize it fits better in this topic. After several evenings trying everything I can find, I still can't get my Phidget code to run without sudo on my Raspberry Pi. Or rather, sometimes it does for a while, but then it doesn't again. Every time it can be solved by ru...

After several evenings trying everything I can find, I still can't get my Phidget code to run without sudo. Or rather, sometimes it does for a while, but then it doesn't again. Every time it can be solved by running it with sudo. But a web page doesn't run like that, so I can't get the web page to c...

Thanks for the reply. I don't know how to check for those things, but I suddenly realized that the problem now seems to be user rights again, which I am discussing in another thread (I can't run phidget22admin without sudo). So I'm happy with the answer here for now, I was just wondering what the &q...

Too quick: it worked for a little while, now it doesn't again. And the same trick doesn't help anymore. This is getting really annoying!

A hope someone can help!

I have trouble getting a web page for controlling Phidgets to work. It seems like things work one time after rebooting, then stop. I have buttons on the page for turning on/off DigitalOutputs. If my "Load" code connects to the Phidget and opens all DigitalOutput channels, are they still av...

I find examples like these for web pages: function connectPhidgets() { var local = location.hostname; //get host location var conn = new phidget22.Connection(8080, local); conn.connect().then(runExample); } What is happening here? Why would I need to do this in a web page (index.html), in python I j...

I finally found a discussion about this in the "Linux" topic on this forum.

All that is needed, was to run:

sudo apt-get install --reinstall udev

and restart! Why? No idea, seems very strange to me, I haven't quite gotten the hang of linux yet, I realize...

I forgot to mention that I _do_ have a file called: /etc/udev/rules.d/99-libphidget22.rules with the content: SUBSYSTEMS=="usb", ACTION=="add", ATTRS{idVendor}=="06c2", ATTRS{idProduct}=="00[3-a][0-f]", MODE="666" should allow all users access to the...

Hi! I can't get my web page to connect to the Phidget. I'm guessing because of user rights somehow. What user rights does the web server have? Do I need to do something special to let it access Phidgets? And that code in connectPhidgets, what does it do? Is it needed at all? When I look at this web ...
