I recently understood that Nedis is an IoT (InternetofThings) OEM-label. (OriginalEquipmentManufacturer – meaning that Nedis buys other manufacturers products putting their own label on them).
Most Nedis IOT´s is products from Tuya, who supplies Nedis with many, if not all of their Smart Home products, as well as the Smart Living-app.
As Tuya sells this OEM-concept of hardware and app, to many other labels, it means that Nedis IoT´s and some other OEM-products could be compatible, even before standards as the Matter-standard. It all has to do with HOW the various labels implement the API´s they get from Tuya. Most labels wants their own look and sometimes their own special functions to stand out from their competition, sometimes this makes their products not compatible with other labels. Whereas some of these products work just fine together, it is not guaranteed.
Tuya is a member of the old “Zigbee Alliance” developing the Zigbee standard (Nedis has 5 IOT´s with Zigbee and many more with WiFi), this Alliance is now transformed into the “Connectivity Standards Alliance“. This Alliance has hundreds of members (but Nedis is not one) an develops both Zigbee and Matter standards for product compatability between different vendors IoT-products.
Therefore the standards of Zigbee and Matter is not really a Nedis issue.
I have made contact with the Tuya organization now, to better understand this standard problem and possibly influence until the Matter-standard has impact. I have been met in a very positive way so far. It seems this is an issue the blog will come back to frequently.
