Temp may be the issue, need to establish why its going up. Which mode is your setup on. SUB/SBU?If SUB, check max charging current set on invertor-could be too high. If SBU check load at time of switchover from PV to Bat. maybe to high. if nothing is amiss, for starters, I suggest a reboot of the system. (the correct way)

For Smart BESS . Install Smart BESS app onto smartphone and create user profile, register and then test login into the app and logout. While connected to your home WiFi with a working Internet connection, do the following. 1. Have your home wifi password written and ready to readoff. 2.Open smart bess and login in to the app 3 . Press reset button on CFE battery for 7s to activate battery inbuilt WiFi signal . make sure its 7s otherwise it won't work. 4. On the Smart BESS interface on your phone press Config WiFi. 5.Smart Bess will pickup the battery's inbuilt wifi (hifyling_softap) and you type in your home WiFi password in the empty row. 6.On your phone settings, go to wifi selection and chose the hiflying_softap as your wifi to use instead of your home WiFi. 7. Go back to Smart BESS and press the start button. 8. Smart BESS will self configure a connection between your battery internal wifi and your home wifi and success is registered once you see a message on your phone screen with ID and a mac address. 9. On smart bess app press Add Battery follow prompts and voila . if battery data doesn't appear when you press "my battery" but you have added it correctly, wait a few hours or check the following day for cfe server to pickup your battery data. Note : Smart BESS just gives basic details about battery status eg voltage temperature,current and individual cell voltages and a SOC graph etc ...not much else to do there except probably to assist you with knowing fault code when there is a fault with battery.. and also probably just to wow a few of your friends with this "technological wizardry :)"

use a RS485 cable with all 8 wires to eliminate any chance of miscommunication. Connect onto BMS port on Growatt invertor not RS485 port , try using protocol 52, usually works, though it will depend on your battery brand.
