Help with TM1814 and wled

[oxytousc]

I've got some cafe lights that I'm putting in my show this year. They're working fine with sequences, but when I turn off a sequence it blinks red, blue, green and white--like a test pattern. Has anyone else experienced this and what was the solution? I'm running Wasatch Quad+ Antennas. I've also turned on blank sequence in FPP. They still seem to do it when I hit stop.

TM1814 will display a test pattern when not actively driven by a microcontroller. I would either put relay on the power line or send some data to keep them off.

Thanks. If I’m running a relay, I gather I’d just connect the relay to the power supply and then splice it into the pigtails?

You would put the relay in the V+ line from where ever your power is flowing to the pixels. On the pigtail makes sense if that is where you supply V+. The WLED support is talked about on this page: https://kno.wled.ge/features/relay-control/

Here is different version of the relay hack https://doityourselfchristmas.com/f...es-pixel-control-to-dc-powered-devices.57561/

And here is another version of using WLED to control it a couple different ways. https://www.drzzs.com/leds/34791/

Thanks! Monumentally helpful.

Would this relay work? I assume it would. Connect the PSU to V+ and V- and then run V+ from each pigtail to the relay instead of the board.

Enable off-refresh, it's under the led setup menu where you add/remove led outputs. - saying this as you mentioned WLED.
