Hosted Grott/AWS about grott HOT 9 CLOSED

Hmmm.... Although Grott can handle multiple inverters (I run it with 2 myself) it is not in basic designed for running a high amount of inverters.

I might hope that nobody want to use Grott for commercial usage without my permission.

Luckily for us it is not that good protect so Grott is able intercept and decode the data.

For Grott (grottserver) I can implement IP-filtering (Check your public IP address). Dat make a a little bit more secure if you want to run it in AWS (or other Public cloud). I know this is not a total secure solution but it might help a little bit.

@thorstenfleischmann No it is no advisable. If you do, anyone could connect to it and spam your DB/submit on your behalf to PVOutput/etc. There is no authentication when it comes to inverter id so it could also be spoofed and your influxdb records for your inverter could be ruined.

tl;dr keep it on your local network only, if you're going to insist on doing it on AWS at least do it over a site-to-site VPN or setup firewall rules to allow connections from your network ONLY

Thanks! How is the logger authenticated at Growatt? Don't we have the same problems with the Growatt servers?

@thorstenfleischmann You provide Growatt with a check code that Growatt tied to your SN. Not very secure...

@thorstenfleischmann There is no authentication actually... anyone could contact Growatt's servers, spoof your SN and cause you to have fake data

I'm not very familiar with aws but I think they already have something like this built in ("security groups").

Yes, IP filtering should be possible on AWS side. Do you just want to avoid a "local" instance ? Or do you want to have one central instance for multiple inverter locations ?

I thought of hosting it for me and maybe a friend.

But finally I concluded that aws is to expensive and I managed to run it natively on my low budget Synology.

But I like the idea of Grott as a service... The friend of mine has no Pi/Synology or anything running.
