 # SolisCloud to PVOutput and/or Domoticz
 Simple Python3 script to copy latest (normally once per 5 minutes) SolisCloud portal inverter update to PVOutput portal and/or Domoticz.
 
-The soliscloud_to_pvoutput.py script will get the first station id with the secrets of SolisCloud (see next section). Thereafter it will get the inverter id and serial number via the configured SOLISCLOUD_INVERTER_INDEX (default the first inverter). Then in an endless loop the inverter details are fetched and the following information is used:

 Make 2 PVOutput accounts (you need 2 email addresses) for each inverter a separate PVOutput account. Make sure to configure the PVOutput accounts and get the PVOutput API keys.
 
-The solution is to have 2 scripts running in different directories (one for each inverter) and for the each directory you do modifications, e.g. the configuration to get the appropriate inverter (setting soliscloud_inverter_index) and send the output to a appropriate PVOutput account as target.

 Create two directories, copy the SolisCloud2PVOutput files (soliscloud_to_pvoutput.py, soliscloud_to_pvoutput.cfg, solis.sh and logging_config.ini) to each directory and configure in each directory soliscloud_to_pvoutput.cfg:
 - solis
 - solis2
 
 In solis2 directory you change the following:
-- modify soliscloud_to_pvoutput.cfg to point the second PVOutput account secrets and change the soliscloud_inverter_index to 1 (to get the data of the second inverter)
+- modify soliscloud_to_pvoutput.cfg to point the second PVOutput account secrets and change the soliscloud_station_index to 1 (to get the second station) and/or soliscloud_inverter_index to 1 (to get the data of the second inverter)
 - rename solis.sh to solis2.sh and modify solis2.sh to go to directory solis2 (line 9: cd ~/solis2)
 
 Have two cronrabs running (for solis.sh and solis2.sh)
