I’m continuing to play around with my setup, and want to expand the power monitoring into home automation. Initially, this is being driven by the (NICE) plugin power monitoring switches (flashed to Tasmota) I bought – Thanks @borpin that I want to integrate the power logging to EmonCMS and latterly I’ll get to adding control via Openhab or HomeAssistant
I’ve seen a few posts that don’t recommend co-installing Openhab / NodeRed on the emonpi (after I’ve done it of course, but seemingly with no ill effects – so far), so I’m looking again what the optimum hardware setup might be, and what to run where.
I have a fair amount of hardware, including
Synology 1819+ NAS 1 x unused PI3 2x Orange PI zero (running PiHole in a High Availability Cluster) 1 x emonBase (with 1x emonTx and a number of emonTH nodes)
and I’m not averse to getting another couple of Orange Pi Zeros to try setting up in a HA cluster for the broker.
After reverting my emonBase to stock, is there any advantage to putting openhab/node red on my NAS over the unused PI3. What about the MQTT broker, Mosquitto ? I understand there will be some config changes needed if i do this, but is there any mileage in shifting that away from the emonBase ?
On a related note – what’s the best way to backup / restore my current emonBase / emoncms config before reverting it to stock by reflashing the SD card with Etcher. When I re-flash, is there any advantage to putting a larger SD card in ?
