Get the app
Install TasmoShelf
Two ways in, depending on the phone. Neither needs an account with us, and the licence is checked on the phone itself.
How do I install TasmoShelf on my iPhone?
From the App Store, where the app is listed for iPhone and iPad; it needs iOS 15 or newer and is free for up to three devices. If you are reading this on a computer, the store link may not get you there: on a Mac the App Store app opens a product page it cannot display, because the app is offered for iPhone and iPad only, and on Windows or Linux there is no App Store at all. In both cases, scan the code below with the phone, or type tasmoshelf.app into the phone's browser and come back to this page there.
iPhone and iPad
The unlock is a one-time in-app purchase inside the app. There is no account and nothing to activate online.
Android
The APK comes straight from this site, so no Google account is involved and no store has to be installed. Android asks once whether it may install an app from the browser; after that the app updates when you download a newer file from here.
Older 32-bit phones need the arm32 build, linked on the homepage next to the checksums.
What it costs
Free for up to three devices, with nothing held back: every control, the energy view, the whole device catalogue. The full version lifts the device limit and costs 9.99 € once, on both platforms. No subscription and no ads.
