INKBIRD IBS-TH5 with remote temperature sensors

I purchased INKBIRD IBS-TH5 from an official store on Aliexpress. The seller assured me that it was possible to display the temperature from the external IBS-TH3 sensor on the device. How do I set this up on the device?

I have read some reviews on Amazon and users write that this feature is missing.

How is it?

Please understand, IBS-TH5 and IBS-TH3 are independent devices, they each have built-in temperature and humidity sensors, they will not display each other’s readings, but they can both be connected to the INKBIRD app to check the readings.
