totally remove old version to install new version

[StijnT007]

6 months ago, i installed a version of sigenergy. When i tried to download vesion 1.1.6 via HACS, I went to devices and services to add the integration. The pop-up asked me to delete the old version. How can i do this? I checked the checkbox to overwrite existing sensors but because the names of similar sensor are almost alike but missing the word "plant". Those sensor were created again.
So now i have the old AND new sensors toghether and the one is blocking and messing up the other sensors to control the battery and inverter.
I deleted the file sig in custom component. reloaded HA, installed the new version with HACS and at it as an integratin.
It keeps saying there is a old version so i needed to check the checkbox to overwrite existing sensors what is not compatible with the old version. (breaks everything)

I would like a clean start with version 1.1.6.

Thanks in advance for any help .

i removed manually ALL senors , templates and autmoations. ( i don't know any more of the template sensors and/or automations are from this repository or from predbat.)
After removing all sensors, i could do a "clean" install.

To be sure , i took read-only first.
After worths , i unchecked the read-only checkbox.

I can change the modus now ( charging, discharging, self consumption)
But i still got issues with the values to charge /discharge.

i'm using the dashboard from https://github.com/Si-GCG/sigenergy_projects/blob/main/Dashboards/sigen_dashboard_fixed.yaml
Do i need to add some other files/sensors also?
To be sure, which sensor do i need to use (set) to control the amount of (dis)charging energy is needed.

In the dashboard, i'm using number.sigen_plant_ess_max_charging_limit for the moment.
