Hi everyone! Hope all is well! I’ve seen on the forums that some people have been struggling with integrating the Atlas Scientific sensors onto the BlueROV system. There are a few different ways to do it, but here is what I did to integrate a conductivity sensor onto my BlueROV: Starting off, in…

[image] RaulTrombin: udevadm info -a -n /dev/ttyUSB0 | grep -E ‘idVendor|idProduct|serial’ I was able to determine the USBttyX gets incremented for each sensor, even when going through a hub. I now have all sensors working correctly, producing outputs. I’ve decided to use a text output to a…

Hi @rsheffield99 [image] Rod Sheffield: I’ve decided to use a text output to attach to a widget in Cockpit, but haven’t been able to assign the url to a custom widget yet. You can either embed the NodeRed dashboard via an iframe URL in Cockpit, or show individual data fields in generic indic…

Tony, I do have the url. I’m getting a “192.168.2.2 sent invalid response” error message, not my text output. Any clue what I’m doing wrong here? [CockpitWidget] I’d really like to lay the 4 water sensor outputs over the mission track at waypoints when collecting the data for visual reference. …

Hi @rsheffield99 - There may be a misunderstanding here - as far as I know widgets can’t be anchored to the map. They exist as overlays within Cockpit. @rafael.lehmkuhl may have some tips, but that URL doesn’t go in a DIY widget - it goes in the existing iframe widget!

You are correct, I thought I could put the url into a DIY widget I put on the Cockpit as an overlay. I am still searching for a way to access the iFrame dialog so that I can add values to an existing top or bottom iframe overlays. The documentation doesn’t address that. IFrame The iframe widget p…

Found it! It was at the far right on my bottom bar. Still getting a broken link when I give it the url for the dashboard text output node. If I change from https to http, I get the entire node-red page. This doesn’t seem to be any different than the DIY widget from an output point of view. [if…

Hi @rsheffield99 - You can check if you’re using the right URL by putting it in a browser- it should load the dashboard. You find the dashboard link within your NodeRed flow, see the instructions here .

Tony, got the iframe to show up both in Cockpit and by pasting into my browser, see below for reference. The url used a /#flow/xxxx format rather than a /#node/xxxx format, but I could move and resize the overlay to show all the sensors, a map, and video all at the same time. I have a question abo…

Hi @rsheffield99 - Cockpit does not have any log playback options like QGC, currently. You can visualize autopilot logs with the tool here , which will show vehicle position vs. sensor values (sent via named value float.) You could also print the messages to the autopilot console (as an appropriate …
