Question about TFA Sun

Hello D.d. hipnotic
Unfortunately, this product is no longer in use at my place. But it served its purpose perfectly. However, the inside temperature was always displayed for me. Unfortunately, I cannot tell you why it is not displayed for you. You may have to set it up again. Of course, it could also be a defect in the unit. Otherwise, contact the supplier if you still have a guarantee on the product.
With kind regards

Thomas
