Description

From the listing uploaded by “appupdater”.

This Smart Boiler app gives you access to a water heater via Bluetooth. The first pairing is protected, and it is necessary to copy the code that the heater will generate on its display immediately after selecting the boiler near 10 meters from the mobile device. Application Options - setting the HDO function - Smart Smart settings - time scheduling (time intervals of hours to days, eg vacation) - Statistics on water heating control (total, monthly, daily) - display of hot water at 40 ° C To set up the service functions, all the necessary information is written in the manual itself, which is part of the intelligent OKHE SMART water heaters package. The manual is also available for download at www.dzd.cz. The application collects and sends diagnostic data regarding heater status and thermostat communication. This data is intended to improve product and technical support. Because of searching for devices on the Bluethooth Low Energy technology, the app requires Android positioning permission in 6.0 and higher. For more information, please visit the Android Developer website.
