We have just had a powerwall installed and need to be able to monitor this. we cannot download the app onto our mobile phones because they are not 15.0 iOS

Do we need to buy new i phones or is there an alternative way around this problem?

Hello, thank you for using Howly.
Could you tell me what iPhones you have?
I meant the models

a 6s and a 7 - okay we are pensioners and not very tech savvy so they seem adequate for our needs so far!


Noted, thank you
iOS 15.7. 3 is compatible with all models of iPhone 6s, iPhone 7
You have the ability to update your iPhone operating system to the version you need

okay, so how do I go about that?

Top answer

I recommend that you update the operating system on your phones

  1. Go to Settings on your iPhone > General > Software Update > Automatic
  2. Turn on Download iOS Updates and Install iOS Updates.

Many thanks. You managed to tell me all this without once cursing a dinosaur in the tech world - unlike my 2 sons!
