Hello there, we hope you're doing well. According to the requirements and mentioned skills, we believe that our team would be the best fit for this job. We will build the application on the API provided by the hardware vendor, and include multilingual support for both English and Arabic. The app will also feature Face ID and Fingerprint Login for added security and ease of use.
We will implement a permissions system to allow for item-wise and group-wise control for devices, and include customer payment, status, and history features. The app will also have the ability to schedule maintenance/sales person requests, and track the status and history of these requests.
In addition to the app, we will also develop a web portal with online sales and customer login capabilities, to allow customers to control, configure, and check the status of their devices. The app will be compatible with both IOS and Android mobile and tablet devices.
We will also integrate 3rd party hardware such as doorbells, thermostats, GPS trackers, gas sensors, etc. to provide a comprehensive smart home solution.
Please let me know if you would like to proceed with our services. We will be happy to provide you with a detailed quote and timeline for completion, including the integration of the terms and conditions and privacy policy. Let's discuss more in chat.
