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.

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.

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

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

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.

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.
