I have a few functionally related questions about the Smart Space Heater S that I was hoping you might be able to help me with.
I purchased 2 pcs of this heater yesterday in the Official Xiaomi shop, Debrecen, Hungary (230V; EU plug).
I set up the heaters in the Xiaomi Home app successfully and start using them.
During the operation, I discovered several & similar malfunctions in the case of both heaters. Based on the product datasheet, I believe those aren’t normal and expected.
These malfunctions do not depend on the way how I’m using/operating the heaters (by application or by manually).
1, The heaters do not switch off when reaching the setup temperature in the constant temp mode. They still operate with a ~800W power (I measured the power consumption with a smart plug) without decreasing it or turn off.
I stopped them manually when the tested room temperature reached 28 celsius. It seems the digital thermometer or the regulator circuit does not work properly.
2, When I turn off & on the heater it starts working with the highest power ~2000W regardless of the set temperature. If I modify the constant temp, it will switch back again to ~800W and stay there until I power it off manually.
I believe these unexpected habits have to be fixed somehow because it can cause fire, therefore in this state the products are dangerous! In addition, it does not make any sense the six different temperature ranges and a lot of other features. I also found comments on different social platforms (Youtube, Facebook) where the users experienced the same issues.
Do you know or experienced similar issues with Smart Space Heater S?
Is there any chance to fix these somehow (a firmware upgrade or a component level repair)?
I’m asking this because those functions were the main reasons why I bought these products. To be honest, without them, this will be only a (dangerous) stock heater and for this price, a much better and safer one can be purchased from another manufacturer.
Thanks in advance!
