The overall installation process is a bit cumbersome, but other than that the app seems to be working. Unfortunately I figured that the notifications don’t work with the most recent (maybe even before) iOS variants. With an old iPhone 5 with an older iOS version it works fine. Would be great if this could be fixed! ### 1/5 — Seit einigen Wochen App plötzlich sehr mangelhaft *2019-03-31, version 1.3* Bis vor wenigen Wochen war auch ich sehr zufrieden! Plötzlich stürzte die App dauernd ab, nun ist die Steckdose ständig offline und das Neueste ist, daß es absolut keine Nachrichten mehr gibt! Vorher top, jetzt Schrott ### 1/5 — App kann nicht mehr geöffnet werden. *2019-03-24, version 1.2* Seit 3 Wochen kann ich die App nicht mehr öffnen und so mit meine Heizung nicht mehr regulieren. Ich bin stinksauer. Wir mussten uns nur ein manuelles Thermostat Kaufen was auch nicht gerade günstig war, dass wir unser Heizung regulierten können. Wir waren bis vor 3 Wochen super zufrieden. Aber nun geht nicht mehr ;( ## Frequently asked questions about DRH ### What can DRH-301 WiFi control? DRH-301 WiFi allows you to control the DRH-301-WIFI smart plug and alarm system.
