looking for zigbee relay

[zealous lotus]

Hi everyone!
I am looking for a relay to switch LED lighting from several LED diodes (Christmas decoration). The LEDs are powered by ~220V. The problem is that all the relays I have used have ghost voltage when turned off. Which causes the LED bulbs to not be off but to shine very dimly.
I have already tried these relays:
Aquara Relay Module T2 in the off state I measured ~50V
https://www.aqara.com/en/product/dual-relay-module-t2
Sonoff ZBMINIR2 in the off state I measured ~6V
https://sonoff.tech/en-eu/products/sonoff-zbmini-extreme-zigbee-smart-switch-zbminir2
I don't want to buy another relay just to try it. Does anyone have experience with a zigbee relay that has ~0V at the output when turned off?
Thanks for any recomendation.

Can I ask y why you’re not just using a smart plug? I have several Ikea ones for various AC Xmas LED “ropes”.

you can add a bypass capacitor to prevent that

Try rotating the plug by 180 degrees

yes i tried
sonoff S60ZBTPF https://www.zigbee2mqtt.io/devices/S60ZBTPF.html
Tuya TS011F_plug_1 https://www.zigbee2mqtt.io/devices/TS011F_plug_1.html#tuya-ts011f_plug_1
Aqara SP-EUC01 https://www.zigbee2mqtt.io/devices/SP-EUC01.html
but the result was the same when switched off, I had ~6-12V

do you mean parallel between phase and zero?
should it have a specific value or can I calculate it somehow?

[zealous lotus]

it's a eu plug that has a grounding pin, but it can't be turned 180 degrees

[frail belfry]

you put it across the load. probably just need 1μF or 0.1μF. I cant remember the specifics. there are some built sealed with cables attached ones for this purpose. but its just a cap. can have a play if you have some laying around. worst case it pops and you try something else. 😛

i am sure if you research it you can find the science on getting the right one to be fair.

Important to note that this is for the low voltage side, not the 230V side

[frail belfry]

no, its for the AC side

[round oxide]

I live in the EU, the plugs can be rotated 🤔

[zealous lotus]

I have both side ~220V

Input and output are ~220V

[frail belfry]

if you search for "led bypass capacitor" you will find a bunch of stuff on the subject

[zealous lotus]

Ok thanks

[round oxide]

Can you show me a picture of the plug?

[frail belfry]

no problem, the basics is that it gives the residual power an alternate route around the load because AC can go through a cap. (yes... this is oversimplified but analogue circuit theory is a dry subject...)

[zealous lotus]

oh, I know what you were thinking, yes, I tried that too
