One of the (semi)professional irrigation systems coming from Toro is Tempus.
Specifically the classic Tempus (not DC) - https://sites.toro.com/tempus/
It has an optional Wifi => remote connection capability. Leading to a possible mobile app control. BTW, looking pretty outdated 
Is there anyone who managed to implement that?
Is there any workaround to do so?
Any chance to develop the integration?
