Information about how the device functions

Hello, This device is a very well working MPPT controller with an Tuya integration which is not very good... in the Tuya app (smart life) is working fine, but we can see clearly that the look and feel is different than usual tuya API... so I feel that they just have adapted an existing API that it work on smart life.... because the information in smart life not that is what i expect (statisitics) I want to use an Home assistant integration... when I integrate this devise using the normal tuya cloud integration . . . HA find the device but it have no entities... I had have the same problem with an Metering smart plug (no statistic in tuya cloud integration ) and resolved this problem by using Tuya local.... so I was hoping to get the same result with the MPPT controller . . .

[Katawengineering]

Sorry...had have wrong DPS information, I change it... now, is the correct one

[Katawengineering]

make a other mistake.... lease re-open it

[make-all]

Please collect the logs again using tuya-local 2025.2.1 (or later)
