Just realized that the German Siegenia Store offers a 20% discount on their smart home products from July through September. Since this information is hidden deeply in the product description I thought I would let you know in case anyone is interested. Use the code “SecureHome” on checkout to apply the discount.

Please note that I am in no way affiliated with the company. I’m just a user of their senso secure devices which I really like. Since they are relatively pricey and discounts are rare I think it is worth sharing this information here.
