How now I am using emoncms with old version 10.1.2 (emonSD-30Oct18) and and old versin of raspberry harfware (Pi 2 Model B) with raspbian 9.9
Now I’m planning to upgrade to raspberry pi3 and latest version of emoncms, but I’m not sure what is the best method to upgrade hardware and software, keeping all data andconfiguration, any doc or step by step for this upgrade of hardware and software?
After upgrade to latest version with new mage seems that data hasbeen restored, but I ahve detected some feed that are showed as inactive and on old version were working… any suggestion hot to debug this issue?
I never bought a Pi3 - always felt the gain for the cost didn’t merit the investment over the Pi 2B+.
While the performance gain isn’t stellar, it is noticable.
But, (unless one has a Pi2B+ v1.2) the Pi3 is able to boot from USB as well.
That may be a moot point too depending on what one wants to do with their Pi.
And… I seem to recall the cost of a Pi3 on this side of the pond is a bit less than it is in the UK.
I want to get my hands on the new 8MB Pi4. That ought to be interesting…
It was the bang for buck that just didn’t do it for me. I still don’t own a Pi3 (except the one in the emonPi and that doesn’t count).
I never saw the point of this. A oneway mod for no discernible benefit - just move /boot on to an old, small SD Card.
You will need the new RaspberryPi OS 64 then .
I’ve got a 4Mb (with SSD) running Home Assistant and a whole host of addons and it is currently using 35% memory. I don’t need any more for this application and it is the most intensive Pi application I have. One thing I did find was the default swap size on Raspbian is really small and a fixed size (SD Card wear mitigation) - expanding that made a big difference to the amount of memory consumed. It seemed, the processes used less swap the more there was (by size not % of course) which was odd - almost as if they grabbed swap as there was not much to be had.
Inputs from fronius are workins but some feeds calculated from thins inputs are not updated.
New image is on pi3 wkth a temporary ip, different from old image, is this the issue? At this momment I am evaluating migratikn result and for this ip is different…
