Glyn - I started working with Home Assistant. I am experiencing a few learning issues with new things like the YAML file for configuration. Very confusing for me! It looks like the HA group is working to improve the config experience. Yay!
Anyway I’ve been going thru the code and trying to get the SD card write usage down so HA can run on the low-write emonPi.
Glyn - On the emonPi (and in the Home Assistant) I can see a 100MB swap file is being setup at /var/swap. It is not in the tmpfs areas. Is this correct? Should swap be turned off?
Below is the daemon.log for the emonPi:

Sorry, it’s been a while since I tested HA. The project looks like it has developed a lot since I had a play with it. I recomend you post public on the forum or try on the HA forum.
Sorry - I should have been more clear. I wasn’t looking for the HA answers. Just how you currently do things with emonPi.
home-assistant_v2.db - This seems similar to the emonPi phpfina and phptimeseries files and I think I’ll add it to the /home/pi/data directory. And add a symbolic link with /home/homeassistant/.homeassistant/home-assistant_v2.db.
system.journal - looks like it is in the emonPi tmpfs /run directory.
The swap file is an unknown for me… I was curious if emonPi should have it turned on. I looks like it is turned on.
