Does anyone know the max effective range for the newest doorbell (E82021F2, 32 gb storage) at second highest sensitivity setting?
I don’t own the product but I do know the electromagnetic force of nature.
The range is highly variable based on how much physical material and it’s type at the two locations (doorbell, base) and in between.
In general the amount of metal between the locations causes more loss than distance. There’s more metal in certain types of brick, less in wood. Metal like wires and plumbing which are near either end will suck the energy out of the signal.
So one location where you placed the doorbell on a metal framed door, with concrete walls and floors, would have significantly shorter distance than a wooden door frame passing through wooden floor and wooden walls.
