Hi All,
I updated the code based on some chats with @mstormi in Supporting spot energy pricing - #26 by mstormi. If you can, please test battery charging & discharging. This builds removes the config parameter for the charge rate and adds 2x new channels for charge & discharge rate - so that the charge rate can be set dynamically. https://smedley.id.au/tmp/org.openhab.binding.sonnen-5.2.0-SNAPSHOT.jar
