Set up the regular Nextcloud install, instead of the AIO. The AIO is not required for any of the things you need, so you end up with lots of stuff you are not gonna touch.

I use Nextcloud with:

• Calendar
• Contacts
• Cookbook
• Notes
• Tasks
• Polls

Tasks can work together with the Tasks.org Android client and there are seperate apps for Notes and Cookbook, while Calendar and Contacts can integrate with your mobile apps via DavX5 using CalDav.

My partner and I use a git repository on our self-hosted gitea instance for household management.

Issue tracker and kanban boards for task management, wiki for documentation, and some infrastructure components are version controlled in the repo itself.

Home Assistant (also self-hosted) provides the ability to easily and automatically create issues based on schedules and sensor data, like creating a git issue when when weather conditions tomorrow may necessitate checking this afternoon that nothing gets left out in the rain.

Matrix (also self-hosted) lets Gitea and Home Assistant bully us into remembering to do things we might have forgotten. (Send a second notification if the washer finished 15 minutes ago, but the dryer never started)

It's been fantsstic being able to create git issues for honey-dos as well as having the automations for creating issues for recurring tasks. “Hey we need to take X to the vet for Y sometime next week” “Oh yeah, can you go ahead and put in a ticket?” And vice versa.

Wife and I use KitchenOwl for grocery list. It’s nice. I should look into using Nextcloud for more.

We use Grocy, specifically with the Android app. We only use the shopping list feature but it can do a lot more.

Our household revolves around the amazing Tasks.org Android app. Originally, I would sync the tasks using a Baïkal server because I prefer lightweight solutions. But since then, I've moved on to Nextcloud because I sometimes need a desktop overview of our tasks (and enjoy the other functionality). Nextcloud Tasks is very similar to Tasks.org, which I prefer over Vikunja etc.

Simple shared task lists have worked very well to keep track of chores, shopping and other reminders

For taking notes, keeping recipes etc. I use Joplin

I've never been able to fully transition away from the proprietary TickTick tasks. Nothing seems to have the features I'm accustomed too. Then again, I'm on a dysfunctional task non-management spree right now, so maybe when I get my shit together I'll try again. For context, I use a modified version of the GTD strategy to keep track of my todos.

Before TickTick I used Astrid. When Astrid tasks was bought and killed by Yahoo, I thought they were over, although it seems there is a fork https://github.com/tasks/tasks (GPL 3.0) that also syncs with tasks.org. I haven't done thorough testing yet to see what kind of issues I would have using this new Astrid and Nextcloud, but this is the best open solution I've been able to come up with and its been on my project shelf for over a year waiting to be tested.

For calendar, nextcloud synced with Thunderbird and a proprietary phone app (I know... I know) seems to work well for me. My partner uses icloud and it generally interoperates fine. I even have a raspberry pi in the living room that pulls in everyone's calendar and overlays them as a "family calendar"

We use markdown notes extensively. Everything is synced to our desktops and mobile devices with Syncthing. Markor editor for Android, and VSCodium/vim on the desktop. Works great for tech notes, medical info, shopping lists, recipes, etc.

We definitely use the calendar on Nextcloud. Everyone has their own one and it's shared with the other. We tried using tasks but that didn't work out for us, but I'd say it's more because of us and not for a lack of tools. Both work with open source apps on Android.

What's worked best for us for our groceries is a dedicated Signal group. By now even our children are in that one.

Paperless for keeping track of text written on the dead trees which companies keep sending me instead of email.

Actualbudget for keeping track where the money goes.

Self hosted version of https://homechart.app/

Not FOSS (source available I believe though) but it has the option of a lifetime license rather than a subscription. Dev is readily available and helpful too.

I recently tried selfhosted grocy. It's really amazing, but in the end does seem over the top for us, so we went back to intuition and communication based "household management" ;)
