The OJ Microline® OWD5 app lets you make the most of your OJ Microline® OWD5 Thermostats: use the app to remote control your home heating system from any location. Like the thermostats themselves, the app is entirely intuitive and easy to handle – making it simpler than ever to ensure maximum savings on your heating bill while still enjoying a warm welcome every time you step into your home. View and set temperatures View your heating schedule – and change it Set your heating system to vacation mode View your energy log View and set temperatures: You can instantly see the current temperature in all your rooms and locations fitted with OJ Microline® OWD5 Thermostats. And make any adjustments you want. Want your holiday house heated for your weekend visit? Need the guest bedroom warmed up for an unexpected visitor? Or your bathroom ready for a nice, long soak when you get home? No problem. View and change your heating schedule: One of the key benefits of your OJ Microline® OWD5 Thermostat is its schedule function, where the thermostat automatically adjusts heating levels to match your usual timetable. However, sometimes you need a bit of flexibility, and this app lets you override the schedule to adjust temperatures as you wish – from any location including your home. 1. Fast-forward to the next scheduled change (e.g. to turn up the heat because you’re coming home early) 2. Make instant temporary adjustments (for example, you might want to turn down the heat everywhere for a good spring cleaning where every window is open) Set your heating system to vacation mode: At times your heating schedule will need adjusting because you’re going away on vacation or on business. With the OJ Microline® OWD5 app, you can plan those adjustments whenever you have a spare moment – and time them to take effect when you need them to. That way, you can walk out the door safe in the knowledge that you won’t waste money on heating an empty house – and that you’ll still get a warm welcome on your return. View your energy log: The app lets you monitor your heating system’s current and past energy consumption at any time and from any location. The app works with the OJ Microline® OWD5/MWD5 Thermostats.

First screen is just a QR code scanner and it will not scan thermostat qr code. I tried taking a picture, printing. App doesn’t say where the serial number is but has a place to enter it. None of the numbers on the device are recognized. Support was an answering machine that hung up ### 2/5 — Could be a lot better *2024-06-09, version 1.6.3* Needs better UX and the energy monitoring is very poor ### 1/5 — Awful Amateurish App *2023-12-17* This app is terrible. It’s partially the app but it’s also the way the thermostats get registered. There’s no excuse for such an amateurish approach to any smart home component. There’s also no excuse for the lack of integration into the available smart home fabrics like HomeKit. ### 1/5 — Please fix the app . *2022-08-29, version 1.5.0* It will not find the QR code . Fix urgently ### 1/5 — App won’t work *2021-12-11, version 1.5.0* Trying to connect to app is hopeless. QR code and ID doesn’t work, keeps saying ‘incorrect customer ID’ but the ID is what the system has generated. Useless! ### 2/5 — Won’t connect to servers *2021-02-09* The app won’t connect or takes a very long time to connect. It had been reliable until recently. I have to change the temperature at the controllers. ### 1/5 — Keine Anmeldung möglich *2021-01-27, version 1.0.4* Leider Kann ich mich weder mit dem QR Code, noch mit der Thermostat ID anmelden. Meldung: Verbindung fehlgeschlagen - falsche Kunden ID ### 5/5 — Empfehlung! *2019-11-13, version 1.0.4* Alles funktioniert bestens. Freue mich jetzt schon auf die Weiterentwicklungen. Leichte Installation. Keine Abstürze. Perfekte Steuerung aus der Ferne. ### 3/5 — An sich gut, aber ... *2018-12-16, version 1.0.4* Die Einzelräume sollten sich auch einzeln voreinstellen lassen, und nicht nur die Zone. Seit gestern springt das Appfenster nach der Anmeldung ständig nach links weg und lässt sich durch keine Maßnahme wieder herstellen (Neuinstallation, anderes Handy, weitere App für Dänemark alternativ). Ich warte jetzt frustriert auf Besserung und hoffe, die Thermostate bald wieder ansprechen zu können. ## Frequently asked questions about OJ MicroLine® OWD5 ### What can I do with OJ MicroLine OWD5?
