* Hey siri remind me every other Tuesday at 8pm when I'm at home to take out the recycling

Some things are more easy to say than to configure with 20+ taps on the Reminders app.

Especially the shopping list. I most often notice that I need something when I'm in the middle of using the last of it, which means my hands are full and often dirty or wet. But I also don't want to put it off because it's something I do need to do.

I have multiple lists set up for shopping so I can say "Hey, Siri, add wood nails to my Home Depot list" or "Hey, siri, add butter to my Costco list".

Works beautifully for me and the lists are shared with our household so it updates for everyone.

How did you originally setup the lists?

You create lists in the Reminders app, then just use the name of the list when adding a reminder.

I'm also a fan of "hey siri, turn off the tv" when leaving.

I have huge gripes with "what's the weather". Siri will for sure say the temperature, which means nothing in a city where the windchill is often ten degrees lower.

If you have a HomePod and an Apple Watch, you can have Siri turn off all media devices when you leave the house. If you have a CRC receiver for your TV hooked up to an Apple TV, you can have it power down the whole entertainment system when you leave.

"Hey siri, lights off" is amazing if you have smart lamp

Fun fact - make a scene named whatever you want - say “rude word the rude word” and then you can tell Siri that and the scene will be enabled! No more “that’s not nice” replies.

>* Hey siri add broccoli to my grocery list

Are you using a specific app for this or is it just a list in Notes called 'grocery list'?

It's under Reminders. If you don't have a list named Grocery, it'll create it and populate it with broccoli.
