My SimpliSafe doorbell lit its own fire this winter

Ironic, device that keeps your home safe can burn your home down.

Hey, at least they didn’t use lemons

Why the hell does this thing have a lithium ion battery in it?

Do we have intermittent power to our doorbells in some settings? I am struggling with the scenario where this makes sense.

I assume this is needed to be able to handle triggering the doorbell chime in series without disrupting other communication or resetting the doorbell.

I thought most doorbells didn’t have power to them directly. They’re just dumb switched

TL;DR: He used 30v instead on 24v, that broke the device.
