My sensors en pump in domoticz

Hello, can anyone help me please? :D

I would like to control a solar water heater with domoticz.
With blocky I do not get that, so I think I need a script here.
I have 2 onewire temperature sensors 1 in the collector and 1 in the boiler and a pump switch.
If the temperature difference is greater ...
