First, this application is ONLY relevant if you have an this app portable battery unit. I just setup the application to work with an EF RiverMax.
Initial pairing via wiFi is complex and error prone. Bluetooth would be a MUCH better option. In particular you have to re pair the wifi every time you power on the EF unit.
Also, there are several settings that can only be set via EcoFlow . No connection means half of the features are unavailable.
Again, PLEASE add Bluetooth support. EcoFlow itself is pretty decent with some nice controls. It's a bit finicky in that scrolling leads to accidentally changing some settings.
Finally, just did a firmware update, and now the unit runs MUCH hotter, not good. this app, if you turn the fan off, PLEASE give me a way to turn it on manually. I prefer a bit of fan noise to damaging my unit by overheating.
