+- A few custom template sensors are required, the code for those are listed inside the apps.yaml template for Sunsynk, copy them
+into your HA configuration.
+
+- An automation is required to update the charge limits across all timezone's:
+
+```yaml

 ## I want to add an unsupported inverter to Predbat
 
 - First copy one of the template configurations that is close to your system and try to configure it to match the sensors you have
