Can you please confirm your Eberspacher heater model and build year, this will allow us to recommend the best Eberspacher controller with a temp display. Perhaps if you are unsure of build year of heater please email a photo of the heater dataplate  sales@butlertechnik.com

Please see attached compatibility list for your Eberspacher Airtronic D4 Diesel Heater 252113. Fortunately this heater model and year is h-kit compatible as you can see on the data label. 

The H-Kit symbol on your Eberspacher heater indicates this ECU version is compatible with LIN switching controller versions.

This includes the Easy Start Select, Timer and Web.

If you are looking to use both a physical switch and app based controller, you can combine the Eberspacher Easy Start Timer with the Eberspacher Easy Start Web. Please see attached wiring diagram.
