Smart switch loop issue

[Dammo6]

Hi DIYer here. I replaced a one gang switch with a no neutral smart switch. I put the provided capacitor between live and neutral in the ceiling rose. All seems fine except that occasionally the light flashes when one of the other switches on the loop is switched on. Is there anything I can do to stop this?

Thanks for any input.

Is the capacitor needed?

What is the make and model number of the switch?

It might be that if you use a filement lamp in the light instead of an LED, it might work fine.

If not, try a different brand of LED.

Yes the capacitor is needed because the lights constantly flicker without it.
I got the switch on Amazon. It's a MoesGo WS-EU-LW-N-MG.
