We have a water softener and dehumidifier that drain in to the sump pump. *
The sump pump output pipe froze, causing the discharge from the softener

alarm that can cut the power to these devices in case something happens
again.

Does anyone know of such a thing?

You should be able to set up the exterior plumbing on the sump
discharge so that it does not ice up causing a blockage. As others
have pointed out, using an oversize pipe, making sure it's sloped down
all the way, etc. should help. You might also want to have a fail-
safe feature so that water can still escape outside even if there is a
blockage further down. For example, the pipe coming out from the
house points down and ends above the open end of the drain pipe,
creating an air gap (like a spigot poised above a drain). If the
drain pipe is clogged the water can still exit the sump discharge pipe
- it might be coming out right next to the house but that is still
better than inside the house. That does make it more noisy though.
