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?

 

[MikeKrebs]

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.

Yea, I have Off Refresh on, but it's not doing it. It needs data sent to it.

WLED has the ability to drive a GPIO when not receiving data / lights are not "on" so that you can control power this way.

Off refresh does send data, "off" data. Might be an issue if xlights is sending live data however, and that may be taking over.
