Watt Butler is a WhatsApp AI for your home solar. Before the next severe weather warning in Cape Town, it helps you check battery charge, backup readiness, and what to do when municipal power drops — like it did last week.
"The storm did not care that you had panels.
It only mattered whether your battery was ready when the grid failed."
Cape Town homes with solar and batteries still lost power when systems were not in the right mode or state of charge. Watt Butler sends practical WhatsApp check-ins before severe weather — so you are not guessing the night the grid goes down.
Leave your mobile and suburb. We are onboarding Cape Town homeowners for the first wave of WhatsApp access.
Before the next severe weather alert, Watt Butler messages you to review battery charge and backup readiness for your setup.
Plain-language guidance: what to switch, what to expect when the grid is out, and when to talk to a human about registration or upgrades.
