Hi i know nothing about coding but with help, I have created a Node-RED flow but it does not seem to be working as expected. Anyone out there that can help fix this? The key issues are:
- The event does not trigger at the correct times/at All
- The SOC conditions for discharging and charging are not being properly checked.
- The manual start and stop functions are not working. Is there anyone that knows coding that can fix this please as ive been bashing my head for days!
