Nedis as OEM
I recently understood that Nedis only is an OEM (OriginalEquipmentManufacturer - meaning that Nedis buys other manufacturers products putting their own label on them) , mostly to Tuya, who supplies them with most, if not all of their Smart Home products as well as the Smart Home-app.
Tuya is a member of the old "Zigbee Alliance" developing the Zigbee standard, this Alliance is now transformed into the "Connectivity Standards Alliance". This Alliance has hundreds of members (Nedis is not one) an develops both Zigbee and Matter standards for product compatability between different vendors IOT-products.
Therefore its not really a Nedis issue. I have made contact with the Tuya organization to better understand this and possibly influence. I have been met in a positive way so far. It seems this is an issue the blog will come back to frequently.
