Hi, I've been trying for 48 hours to get this thing working but I've encountered a lot of difficulties and honestly I'm a little lost.
I have a Raspberry Pi3 B as hardware. photovoltaic inverter is edison 3024 and uses wathpower like many.
I have attempted to follow BarkingSpider's guide and as I said I have had various problems and nothing seems to really work.
I managed to install Raspberry OS Minimal as described in the guide.
I managed to create the solar user and with a lot of effort insert it into the sudoers group (not explained but I think necessary)
I installed phyton 3
I managed to log in remotely with ssh using the solar user, I noticed that it still asks for the password, I think it's wrong..
I managed to install grafana
I managed to install prometheus and node_exporter but both don't start on boot and give some errors
now if I connect to port 3000 I find the grafana homepage which seems ok, however ports 9100 and 9090 do not respond.
if I start prometheus manually port 9100 responds but if I restart the system it won't do so anymore. 9090 there is no way that responds instead...
I'm very frustrated and I don't know how to continue given the amount of problems and errors, my only hope is that someone can guide me and explain what I'm doing wrong.
so please help me.
I wrote a summary of the situation so as not to make the post too long
