The issue resurfaced, unfortunately.
Yesterday I have received new goodies from Aquacomputer, namely more LED strips and another reservoir ring. I have installed a set of three 30-LED strips on top of my monitor (with more to come) and the reservoir ring on top side of my reservoir, so now I have one ring at the top and one ring at the bottom of my reservoir.
So I went in Aquasuite and extended the effect to cover both linked rings, and with that I have changed the effect from „Laser” to „Wave”. Surely enough, after a while the effect stops working by itself.
In Aquasuite I can still see the liquid temperature changing, but the LEDs no longer work. If I go and disable, then re-enable „Control Speed by Data Source” setting, the effect starts working again... for a while.
If I restart the computer while issue is ongoing (non-responsive LEDs), the issue is carried between restarts, prompting me to suspect something being wrong in Farbwerk 360 itself.
If I shut down the PC while the issue is ongoing, upon turning the PC back on the LEDs come back to life, so cutting power from Farbwerk resets the problem.
Out of the two Farbwerk outputs that are temperature-controlled, sometimes only one would stop working while the other would continue to work. Another thing: if both outputs are unresponsive and I disable/enable the temperature control setting on one of them, the other comes back to life too.
Before this, while there was no issue for Profile 1 since July, the issue was present for other profiles, so I have not used them, praying for Profile 1 to still work. And work it did, until I changed the effect.
Interestingly, the monitor ambient light strip works very well even while the temperature-based effects stop working.
I have taken a video capture of the issue, showing the Aquasuite interface, a stopwatch app and a webcam footage of th LEDs themselves. I will edit the video and upload it to youtube shortly, then update this thread.
LE: here is the video. The video is unlisted, meaning only those with the URL can watch it.
