Outdoor timed 12v relay / power adapter available?

Hi guys, my switched gardena 12v power adapter died on me this holiday. I used it to water part of my garden while I’m gone.

Do you know if there’s any independent timed 12v power adapter which you can setup and controle remotely? I want to be able to switch it remotely but it should also work independently if my HA setup fails.

12v relay on an ESP home chip the way to go? Or is there something proved and tested I haven’t found yet?
