My relatively new Bosch dishwasher has real buttons and an LED display. No wifi required
Looks like we got lucky. My unit is a couple years old and has physical buttons, a display, and no wifi. It's been discontinued. Looking at Bosch's site now, there are no models without wifi. The cheap ones (mine was in the "300 series") now lack a display, have touch buttons and require wifi.
I have button and LEDs, and it works fine without wifi for "basic functions", but for "advanced functions" like washer deep cleaning I would need to use their website.
I just bought one and yes, mine also comes with WiFi but it's 100% optional: all features are available in menus or physical buttons too. (Including the infamous rinse cycle the blog post mentions)
It's a European model ("SMV4HAX48E", I'm in EMEA) so it might differ by markets.
Same, my mum got a new Bosch Series 4 last year and it doesn't have wifi at all. Everything is on the control panel.
