I was going to say more but everyone else has already put up everything

ExperienceDoes the user trust your app?How does your app provide feedback?Is your app easy to use with the devices?
UtilitarianSetup / Data EntryOnboardingTroubleshootingCustomer Support
Get ReadyIt is all your fault even if it is the device that messing you up
I18N/L10NMake sure that your app has a great experience across languages and cultures
Constantly BetterThere have been 4 updates since I purchased my Tesla and it now drives me to work and I can use my phone to pull my car of the garage
Brand SupportWhat do you do when your brand has multiple connected devices?How does your app compare and work into the Out of Box Experience (OBE)?
AndroidTreat android as a first class citizen on par with your iOS app

SecurityAre you thinking about it?How do you connect the backend?How do you connect to the device?When you interview, make sure you fake it!
LoggingLog all interactions with everything
TestingIntegration testing is hard to automate, take a lot of time and costly to changeMake sure you have great manual tests and scripts, seriouslyMake sure you performance and usability test!
TeamsHardware and software need to work together in perfect harmonySmall team communication is easyLarger teams need protocols and documentation to avoid running off the rails
Connection FatigueI wanna disconnect myself, do it I wanna disconnect myself, get it I wanna pull my brain stem out, do it I wanna disconnect myself right now
SummaryHopefully you learned a few things and are excited to start working in IoT because the robots are coming
