### 4/5 — Need delete home option

*2026-07-21*

So far, I’m loving my new water heater. I do have one issue in the iOS app. I tried to set up the water heater in the app (prior to powering it up) and followed the onboarding process to add my home. After powering up the heater and finishing its initial test, I returned to the app where I was presented with the onboarding process again asking to add a home. I assumed it didn’t save the home because of a timeout. This was not the case. I now have two homes—one has the heater connected to it. When looking for a way to delete the extraneous home, I couldn’t find any options for deleting it.
