Wynd

This app is very unreliable when it comes to showing the battery life of my Wynd air purifier. I previously had an issue with the app stating I had 77% battery life on my device, but it kept shutting off after a few seconds. I thought my device was broken shortly after receiving it so I contacted Wynd. I found out the battery had 0%. I charged it and worked fine. 6 months later, 66% battery life and it's actually 0%. I cleared cache, force closed, rebooted phone and still said 66%. Unreliable!!!

Updating my review to 4 stars because the developers have been very responsive to fixing reported problems. At this point, the app is solid but somewhat light on features. Would like to see the ability to tweak the automatic Halo/Purifier functionality. As-is, my purifier runs on medium almost all the time because we have a .2 VOC baseline on most days. Since the purifier doesn't actively reduce VOC levels, this just generates higher noise levels and wastes energy. Would like to be able to configure what Wynd components will trigger the automatic activation. That way, I could have it automatically turn on for particulate matter (e.g. smoke) while cooking but not have it running on medium all of the time. Would also love to see more variable speeds. So instead of Low/Medium/High, the speed could gradually ramp up as the Wynd Score goes down or the PM density goes up. Would also like to see a filterable UI and some sort of open API so that those of us with home automation systems (I use Home Assistant) could integrate with other components like wirelessly-controlled exhaust fans.

Very poorly designed program. You have to jump back and forth disabling your 5 GHz network connection to allow your phone to connect to the 2.4 GHz connection of the Halo. Then you get untold numbers of "unknown" errors preventing the program from finishing. IF BY SOME CHANCE you ARE able to finish setup, the equipment will just randomly quit connecting to the network forcing you to attempt the whole flawed setup process again. Support emails are worthless. They never reply.
