I'm finding it surprisingly difficult to find an optimal SSR to safely switch a low-power 230 VAC appliance (air extractor) using a 3.3V GPIO. Ideally, this would be normally connected (so that when I power down my pyboard the switch is on). The best I could find is this: https://whadda.com/product/1-channel-so ... le-wpm332/, but I'm not completely sure if the signal and the load are fully isolated.
Does anyone have suggestions?
SSR recommendation
Re: SSR recommendation
I used some FSS1-102Z but they have a 4-5V switching level. Maybe there are some similar 3V3 parts in that product line.

Thanks, I'll look into it. For now I'm leaning toward something like a Celduc SUL842070 SSR, which should be pretty safe.
