Shows blank screen on 608PD charger comes up in Chinese however it does allow you to rename it that gets displayed below what I would imagine is the charger identification that is Chinese not the actual name that you name it. recover function does not work either. so this basically is non functioning for the 608PD which is an extreme shame considering I don't like the ISDT Link. yes I know the 608 don't have a balance discharge for storage charging. so added as a quick option in the program

I don't know why ISDT decided to randomly add a new name Limeta for their products which just confuses everyone. If that wasn'th bad enough, they now have 2 apps that do the exact same thing. Up to now, both ISDLink and this app worked with all devices both ISDT and Limeta brand. Now they purposely limited their newest product the PB20 to only work with this app. It makes zero sense ISDT is a respectable company that has loyal customers, so now 2 companies selling same product and 2 apps..

Great application. I used it with MASS2 desktop charging station. I wish that we can add custom names to the 8 output channels to help distinguish them.
