Install on Raspi Zero W (32 bit)?

[SR7673]

Here we are!
I did attempt to install influxdb2 on a Raspi Zero W and found that this tool only works on 64 bit systems. Due to the limited CPU performance and RAM of the zero W i decided to stay at 32 bit and a CLI only (no GUI).
As far as i understand for now, Grafana does not need a GUI-OS because it is configured either via CLI or over a web api, right?
Instead of influxdb2 i would simply try influxdb, which is available. Could that work?
But first of all i need to set up mosquitto...

Hello,
I've also installed it on a headless debian instance over cli.

And yes grafana doesn't need a UI, you write the settings into a conf file, startup the service and then you open it remote from a browser and finish the setup (add users, create dashboard's, ...).

Theoretically your setup could work. But I have my doubts regarding the performance of the raspi zero, since the requirements for grafana alone would need almost all the resources (1CPU and 255MB grafana HW Requirements). So yes but if I had to guess: slow ... but hey never try never know.

Instead of influxdb2 you could use many different DB's as Datasource see possible datasources, with telegraf even more see telegraf output plugins.

Hope that's helps

Now i'm getting a bit more familiar with MQTT. https://www.elektronik-kompendium.de/sites/raspberry-pi/2709041.htm
Useful. Maybe it is some additional help for others who start with this so i thought it won't hurt to collect some links even here. Usuall i do this on my own but why not doing it public...
