How do i view log entries from yesterday

what do you mean it’s not enough to run Home Assistant
the raspberry pi 3b with 1GB RAM was the recommended device according to the installation guide when I installed HA a few years ago and if we go by the screenshot from earlier we would need ~700mb and not 28 to fill up its’ memory
but I guess if the system says the memory is full then it’s full…

Will a HomeAssistant Green be future-proof enough if I only intend to use it as I am right now + a few extra devices or should I get the yellow one?..

You can run HA fine on 1gb now, but the more addons you add, the more memory you use. This is like any other computer. If you outgrow your current hardware, you have to upgrade it. Reduce the number of addons that you’re using and your memory footprint will lower.
