But since I’m not switching high-power coils or anything I was advised not to break my head on it :p
So I only need to figure out which Logic mosfet i need

Thanks for the info fietsenrex, I'll probably leave it as it looks like nobody really uses a snubber.

You might consider the IRLB8721 for a mosfet. These are nice because they can handle a really large load without a heat sink. Way overkill for a relay but hey they are easy to work with and will cover just about anything. These turn on with 2.35v so they work with any MCU.

The reason I ask is because I was having all kinds of issues with Reef Angel including outlets not coming on/off when they should and weird flickering on the PWM LED channels. If I unplugged most of the stuff from the outlets, things would go back to normal.

Yeah they doesn't have the snubber but neither do I or likely anyone else. I might have just got caught up in it, thinking about it now maybe devices that require a snubber have that as part of the circuit for the device, that would seem to make more sense. Not sure why you were having that issue, sounds like noise was maybe getting into the DC side of the circuit, not sure. I use to have some similar issues were noise would get into the display and lock it up but that's been long solved. The way it's setup everything is isolated except the GND and I'm probably going to isolate that as well. I haven't had any major issues from the power bars except an odd relay dying but with the GND isolated as well it's even more protected. I just got some PH and EC circuits I made up that have full isolation, after I test it I'll pass it on to the power bars.
