Just had the experience of designing a multiple outlet web switch. JAVA/Browser UI with python/RaspPI controller.
In this case I had some serious in rush current issues for a couple of devices being controlled. Ultimately switched to SSR's that were rated at nearly 10 x the current rating of the devices to avoid welded contacts or fried SSR's. It works, but I'll probably re-write the software with a custom GUI and skip the web sockets for udp.
