As far as the system goes, its a “low-write 9.8.28” fully updated as per the discussion in [Emonpi low-write 9.8.25 - inputs stopped working](https://community.openenergymonitor.org/t/emonpi-low-write-9-8-25-inputs-stopped-working/5945)

The RAM usage has been increasing in line with the MQTT data feed.

So far no crash, but were at 75.1% ram usage and stability will become an issue soon.

emoncms is pretty stock.
