You set the weekly schedule and the next day it has reset itself and turns on whenever it wants. Tragic.

Attention, installation of the thermostat in the SmartTherm app can only be done via an Android phone. Of course, once it is added as a device in the app, you can view and control it through the same account and app from an iPhone. Regarding daily-weekly scheduling, you can set the temperature you want the space to have at specific hours and days of the week, e.g. every day at 06:00 to have 20°C, at 10:00 18°C, at 17:00 21°C, etc. That is, you cannot set the burner to turn on at a specific time and for a specific duration; what you set is the temperature you want in the space during defined time periods. Of course, if you set 7°C for some periods of the day and week, it is essentially like turning off the burner. A different perception of thermostat operation compared to the majority of others, which may suit some people. Others will simply adapt and others will pass it by...
UPDATE --- Through the app, scheduling (24-hour, weekly) is indeed easy and clear, eliminating the difficulty that existed through the remote-controlled device-transmitter.

The installation is easy as long as you have a basic understanding of reading the electrical diagram. As for the settings, I would say that the control from the thermostat is convenient only for the manual simple operation with temperature adjustment. For weekly or daily programming, it was a bit difficult for me, and I started to feel frustrated. The setting with the wifi and the use of the app is easy and straightforward. Once you enter the application, everything is simple and organized. You can very easily set daily or weekly schedules with all possible options for time intervals and temperatures. Therefore, once you install the module, you download the application, easily connect to the wifi, and you can relax knowing you have all the options simply in the app. I recommend it, and it is excellent VFM for a thermostat with a separate module.

I had interference with it and once it turned on the heating in August at 35 degrees!!! Generally, it did whatever it wanted. The temperature changed by itself, it changed programs... It's unacceptable that they don't have a unique communication code between the transmitter and receiver.

It looks good. I replaced an old analog Siemens with a rotary. The transmitter fit into the same mounting holes, they have the same dimensions.
The apk is very easy.
For the connection:
The live wire to L, the neutral to N, the command to NO (normal open), and a bridge is also needed that connects L to COM.

I have been searching for a good room thermostat with wifi and wireless transmitter for a long time, in order to connect it to an oil boiler, as the installation position of the thermostat is in the wrong place. After reading the good reviews about the Stege SG100, I decided to get the SG300, which met my needs. The receiver installation is very easy for someone with basic electrical knowledge. Very easy programming, covering, wireless transmitter connection, and wifi connection. The Smart Therm program is easy to use. A very important factor in choosing this thermostat was that it covers the temperature at which it will turn on and off in relation to the selected temperature. For example, with a covering of 0.3, if the selected temperature is 21ºC, it will turn on at 20.7ºC and turn off at 21.3ºC. Attention: the installation requires a neutral wire to work! The only negative point I would mention is that the user manual is in English, which may be difficult for someone who doesn't know the language.
