yesterday the connection to the app on the mobile worked without any problems. but this morning the app is nice to the zendure 1500. part of the function is working but I don't see the online charge status from the PV and neither does the current station charge status. 24% lights up at the station. But it's still 26% in the app.. the app doesn't show the online charge and discharge values. I'll admit that I'm already angry with Zendure and I'll probably return the product to the store because of its unreliability. it's not the first time it doesn't work properly.
