I have two Tracer-BP solar chargers, two MT-50 displays, two eBox-WIFI modules, and a BLE module.
This app will ONLY work with the BLE module, the Wifi is broken and fails immediately - it does not even try connecting.
Functionality wise this app is really poor. You can “read” and “write” basic configuration to the Tracer-BP but nothing is real time - it doesn’t display the live info automatically or do anything itself, like you get with the MT-50.
You need to request a “refresh” each time you want to see the the current info, which takes a VERY long time over BLE - it is likely requesting every single parameter sequentially, rather than asking for only the current info displayed on the status screen, or requesting “all current status info at once” which would be far more sensible and faster.
It really only provides absolute bare bones basic functionality and is a poor substitute for an MT-50.
I should also note that you can configure the Tracer-BP to Lithium using the app (which you can’t do with the MT-50) there are still further Lithium parameters to set that are not available in the app - to set those you need to use the PC software “Solar Station Monitor”.
