Hi all.
I have a photovoltaic system with an Azzurro ZCS inverter connect to the network and the app for the phone but not compatible with home assistant. I want to let home assistant know the actual charge off the battery but I don’t know how to retrieve the value.
I thought that a good idea is to read directly the voltage of the battery (max 90volts) but I don’t now how to let the esp32 or other similar hardware read the voltage value.
Someone have some ideas ?
Thanks all 
Same for me!
have you booth requested and received AUTHCODE from zcs zucchetti for using their API?
I’m working on a custom component that will polling their API and create a sensor in Home Assistant
Let me know if you are interested…

it will be installed shortly, along with 10KWH worth of battery.
I could help in debugging starting the end of Sept 2021.
thanks
Add this repository to your HACS
Ciao devi inviare una mail [email protected]
e chiedere l’accesso alle API.
Ti invieranno un pdf con un codice Authorization il quale va abbianato al tuo serial number inverter (thingkey).
In english 
Hi you have to send an email [email protected]
and ask for access to the API.
They will send you a pdf with an Authorization code which must be matched with your inverter serial number (thingkey).
No local access for ZCS inverters? Only cloud?
Seems that only cloud access to data is available
Did you ask ZCS or is it just an assumption?
It’s only a my assumption. Feel free to ask they yourself and to get info about a LAN protocol…
I will. Because probably I will install their inverter and would prefer not to depend on the cloud to monitor it. Will let you know what they answer.
In case they confirm only cloud, I’ll use your component, thanks in advance.
Tried to nmap their inverter and no open port except a network diagnostic (but no energy data).
You could try to sniff all traffic from the inverter (it basically “calls home” and upload its statistics from time to time) and try to sort out the payload, unless they make an encrypted connection but this is far beyond my level of expertise.
Will rely on pulling info via API (which is awful not because of @sdesalve work but because of their servers) for now.
And maybe setting a transparent proxy to pull the info before getting to internet at a later stage.
The other alternative is by physically connectin to some serial (currently not exposed) and poking around with their communication bus.
Let me know what you discover.

First install custom_component and restart HA. Then edit configuration.yaml and the restart another time.
O stacca la corrente… se non si rovina niente, al riavvio funziona tutto:rofl:
yes, it’s exact
Thingkey is a serial number of inverter.
Authorizartion send a email to ZCS 
Hi all; i 'am testing integration but logs say:

Anyone solved it?
see above response
the name is same
