I like to develop a water level monitoring for my cistern tank: empty level, low level, mid level, high level.

One of my booster pumps broke because it runs even when there is no water in the cistern tank. The cistern tank is filled via a float valve from the elevated raw water.

One of my option is some previous answer related to water level monitoring:

Is there a risk of 220 V AC flowing in the water, and how do I avoid that? I don't know microcontrollers or programming, so I choose hard wiring and an indicator light.

A second option is to use floatless relay like the ANLY A61F-G3.

But how to have an indicator light at the low limit (E4) and high limit (E1) separately? The indicator light option is available only for low (E3) and high (E2). How to have water level monitoring regardless if you have a motor or not the simplest way? Example: I want my pump to stop working anything below E4 and start pumping when it reaches E4. Is that possible with the floatless relay?

Note: it is not about the monitoring of the filling by the cistern pump, but preventing my booster pump from working if there is no water in the cistern tank.
