Consider dropping influx DB on the pi and use the light weight prometheus DB instead. Then everything works well on the minimal Pi Zero.My hardware tinkering is coming to an end finally, once I complete the final battery pack and finishing tweaks.
Next up Software:
Raspi-4B, Node-Red Grafana, INfluxDB, Python.
Samlex EVO -> ModBus <-> USRIOT-410S <-> Raspi
Midnite Classic -> ModBus <-> Raspi
4 Chargery BMS8T -> RS232 -> USR/IOT-N540 -> Raspi
1 JBD 12V/120A -> UART-PC -> Raspi
The USRIOT / PUSR devices interface RS232/RS485 devices to Ethernet IPaddress : Port which I will have to sort out on the Raspi side... On Win-10 accessing the sub-ports is a freakin nightmare and have to use VCOM (Virtualized comm ports). Hopefully with Raspberry OS NIX it will be easier to work around.
I already have a setup running with the Midnite Classic & Node-Red to Influx & Grafana, so I'm going to pick that up and build out as above. Having already experienced the "fluffy influxDB" I'm installing a 1TB M.2.SATA as I have a feeling it will get quite fluffed with all the datasets. A Good Winter project for January & February.
See my github page for details on the setup.
Using windows as a server is not feasible, unix is the only way to go.
For most cases, a 32gb onboard SD card on the pi is plenty of storage, no need for external drives.
For backup, simply push the prometheus prom files with scp to a low cost cloud server running Centos or Ubuntu, install Grafana again with and you have world wide visibility of your data.
