blink random color when turning on with relay (using SSR to control AC power to PSU)

[doronazl]

What happened?

im using a SSR to control my PSU and turn it off when not in use, it works fine but im getting a blink sometimes when turning the led on, been reading about it and found this thread
#812
seems this was solved there but trying to edit the changes proposed i find things are different in the current code so im stuck

how do i get this done , id like to add a 200ms delay

just tried using usermod multirelay, the problem with is is the minimum is 1 second, it cant do ms, i cant set it lower than 1, if i try to put 0.2 for example, it wont save it and go back to 1

@doronazl could it be you are regularly deleting / changing your questions? I got some questions by e-mail but they are missing here, so hard to help you.

About multi-relay:

• the delay time is an integer (whole number) for seconds. So you can have 0sec, 1sec, 42sec. But you cannot use fractions like 0.34567 sec. If you want finer control, either modify the source code, or make a feature request.
• (deleted question 1) if you enter GPIO pins in the usermod, make sure to not use the same pin anywhere else. So in LED settings, you have to configure the relay pin as unused (-1).
• (deleted question 2) P0...P7 are for the port expander, if you use one. Otherwise don't use P0 ... P7.

My apologies, some issue i got resolved so i just deleted it.
All i need now is a way to do ms, not seconds.
Wouldnt know where to modify and what 🫤

Before you modify code, it would be smart to first verify that the MultiRelay usermod does indeed solve your problem, by testing 1sec or 2sec as the delay value.

If that question is answered "yes", you could try to modify this line in the source code:

WLED/usermods/multi_relay/usermod_multi_relay.h

Line 225 in 1dab26b

if (_relay[i].active && _switchTimerStart > 0 && now - _switchTimerStart > (_relay[i].delay*1000)) {

Changing the * 1000 into * 100 modifies the resolution of the input value (from 1sec to 100ms units); so if you now enter "3" in the UI, it actually means 0.3 sec.

Will do!! Thank you so much

so basically if i change it to *1 then i can treat my input in there as ms right ?
so inputting 300 would mean 300ms ?

Just curious - what is the magic about exactly 0.2 seconds delay? Would the flicker still happen with 1 second delay, or longer?

the UI wouldnt let me go lower than 0.2, i read somewhere even 50ms would be fine to avoid the flickering

a 1 second would work as well but its too long duration and its noticable.

It would be very nice to add a delay for the data as discussed here #346 . Unfortunately it is closed even though the workaround proposed there is a bad one imho.
To simplify things, wouldn't it easily be possible to add a static, blanket delay of 100 or 200 ms if "Relay GPIO" is set in the config? That would be so nice and would prevent recurring issues like this.
