1 PUT INTO USE
You should at least have your raspberry prepared with the sd-card installed. The zigbee module you could connect later.
If you connect the power, the rpi boots and starts an accesspoint that you have to use for the connection with your wifi network.
Open the wifi settings on your computer/tablet/phone. After a while (this can take several minutes) you will see an accesspoint RPI-ECU4. Connect to it with the paswd 'rpiecu123'. if the AP name is RPI-ECU, the passwd = rpiecuabc. In the versions <4_0 this was RadioAP and rpiradio.
Now browse to http://192.168.4.1/ and enter your wifi credentials as well as a username/password for the security of your webpages. Click save and wait for the reboot button to appear. Click it. note: The security credentials are needed to get access to the settings of your ECU.
Next the Raspberry reboots and tries to connect to your wifi. This may take a while! You can find your Raspberry's ip address by browsing to http://rpiecu.local/. Or open your router's webpage to see the connected devices to find the ip address. Or use a wifi analizer tool on your phone/tablet.
If you are inside your own network you see a link to the menu right above in the webinterface.
You should start with expanding the filesystem. Go to the menu 'system' and click the button 'expand'.
After the necessary reboot you nay find that the info on disk usage not has changed. This is normal, it will be correct after the next reboot.
You should wait for influxDB to run before taking further steps.
When you go to menu->databases you click 'choose action->healthcheck influx' to find out if influxDB is running.
In the disk image there is data from my inverter0 present so this should be wiped. Go to menu->databases and make sure influxdb is running by using the 'healthcheck influxdb' command.
Now choose the commands to wipe the databases (see picture)
Alternatively you can do a factory reset to wipe out all remains of my inverters and databases.
Next we should setup the timekeeping. In menu->info you can check the systemtime. Your timezone is currently suitable for Europe. If this isn't correct, go to menu->system->timez and set the correct timezone.
In the menuitem 'settings' you have to enter the geographical coordinates of your location (google for latitude on your city). Now your system can determine sunset and sunrise.
If you want to restore your former system, now is the moment. Please see database restore
In the menuitem 'settings' you have to enter the id. nr. for the zigbee coordinator, this must be a 12 character string, like D6B3011B9780.
For financial calculations you should provide your currency and energy price.
Now you have a complete fresh install, you can register your inverters to the system. Go to inverters to find out how to do it.
When this is done, you have a working system.
