ᐅ Smart Thermostats with Apps – Recommendations, Costs & Real User Experiences Wanted

Hello everyone,

I am currently planning to upgrade my heating system with smart thermostats controlled via an app. The goal is to be able to adjust the temperature using a smartphone, create heating schedules, and control the heating remotely while away from home.

Before deciding on a specific smart radiator thermostat, I would appreciate your recommendations and feedback:

General questions about smart thermostats

• Which smart thermostats with app control do you recommend?
• What has been your experience with app control?
• What should one consider when choosing (e.g., compatibility, reliability, ease of use of the app)?
• What are the prices of the thermostats you recommend (individual units or sets)?

From a practical point of view, I am interested in user experiences:

• How reliably does the app work in everyday use?
• Have there been issues with connectivity, updates, or server outages?
• How easy was installation and battery replacement?
• What are your experiences with the display, backlighting, and readability?
• Are features like geofencing, window detection, or automatic heating schedules useful or just gimmicks?
• I look forward to your opinions, recommendations, and tips – please feel free to mention the model you are using

Thank you in advance!

Experience with my ex and my children: Radiators with thermostats from Homematic, including wall thermostats in the living area.

Without going into detail: They do exactly what they are supposed to do. Work without any problems. Runtime so far is a little over one year (without battery replacement).

Thank you for your reply.

In the following situations, does it make sense to use a wall thermostat or not?

• Attic because of 2 radiators?
• Living room/kitchen because of three radiators?
• Not in the rooms because there is only 1 radiator each?

Which products are recommended? Bosch, or are cheaper alternatives better?

Thank you

Does anyone here have any additional experiences or information to share?
Thanks
