The Energy Manager App unfolds its full potential in connection with a fully integrated smart meter from B-control. The Energy Manager EM100 is the ideal energy meter for capturing the power consumption of your house in real-time and directly taking action to lower energy costs. Through an easy data transfer via ethernet or wifi you can call up your power consumption conveniently from a smartphone, tablet, or PC. The Energy Manager App offers a multitude of graphical assessments, which document your success and identify further possibilities of saving resources. The following functions await you in the app: - Display of momentary consumption - Display of momentary consumption as progression curve - Display of consumption itemized according to your 3-phase connection - Energy Stopwatch: measure the costs of individual appliances - Budget calculator: Keep an overview of your monthly budget - Display of past consumption data in diagrams - Display of your electricity tariff - Display of current meter readings You produce your own energy? The Energy Manager EM210 enables you to optimize your energy supply. You have control over when you draw and feed in power. Through the controlled usage of your self-produced power you not only sink your electricity costs, you also reduce the dependency of rising prices in the electricity market. In connection with the EM210 you have access to the following additional functions with the app: - Display of momentary power supply or feed-in - Display of all past values in diagrams designated as power supply or feed-in With the EM300 the individual circuits can be read out with the B-control sensors via the RS485 interface of the Energy Manager. If sensors are connected to the EM300, the following values are available in the app: - Power consumption values of individual circuits in real-time - Power consumption of individual circuits as a real-time curve - Historical consumption data of individual circuits in diagrams - Comparable representation of the consumption data of individual circuits ## Key features - Real-time consumption display - Appliance cost tracking - Monthly budget calculator - Historical consumption diagrams - Self-produced energy optimization - Individual circuit monitoring ## Recent user reviews (6 of 6) All indexed reviews: https://appshunter.io/ios/app/b-control-energy-manager/id888211362/reviews.md ### 1/5 — Am iPhone schlechte Darstellung *2025-10-26* Gibts eigentlich auch mal eine Weiterentwicklung? ### 1/5 — Stürzt seit dem Update auf iPadOS 17.1.2 ab *2023-12-02* Die App hat bisher funktioniert. Seit dem Update auf 17.1.2 stürzt die App bei Zugriff auf Statistik oder Aktuelle Werte immer ab, d.h. ist jetzt mehr oder weniger nutzlos. Ich hoffe das Problem wird bald behoben. ### 1/5 — Kein Support mehr *2023-02-18* Habe den B-control Energy Manager EM100. Keine Updates mehr in der Firmware, keine Updates mehr der APP. Darstellung der Anzeigen unter IOS fehlerhaft. Gerät nur über die Webseite nutzbar, dort aber auch mit fehlerhafter Bedienung. ### 1/5 — Seit Jahren nicht aktualisiert- Darstellung fehlerhaft *2021-07-21* Leider ist die Darstellung auf dem Handy seit längerer Zeit kaum noch vernünftig zu entziffern. Die App ist seit Jahren nicht aktualisiert worden. ### 1/5 — Nicht mehr zeitgemäß *2021-07-06* Muss dringend an die aktuellen Geräte angepasst werden. ### 1/5 — Funktioniert nur bedingt *2020-10-11* Das Bild wird leider nur zu 2/3 auf meinem Handydisplay (iphone Xs) angezeigt. Es wird nur in Breitbild angezeigt und kann nicht gedreht werden. Die Anzeige ist sehr klein und kaum lesbar. Sry aber so ist die App nicht verwendbar. Firmware 2.04 App- Version 1.25. Wenn es eine Lösung gibt, vergebe ich gerne 5 Punkte, denn die Browseranzeige auf dem PC und die Funktionen sind sehr gut!! ## Frequently asked questions about B ### What smart meters are compatible with B-control Energy Manager?
