I have two Adax Neo WiFi last generation panel heaters. 1000W and 400W. The Adax app found the 1000W. When I try to connect the last one it says that it can’t find any more units. Has anyone experienced the same problem? ---

Hello and welcome to the Homey forum. Did you check / update the firmware as per instructions? The 400W might not be compatible when it runs older firmware > ![1000036266](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/d/6/d694d2f4225e3b10d04049681a8d141b1ed69d6a.jpeg) ---

Hi! Thank you! Yes I did check that and the firmware was up to date. I deleted the panel heater from the adax app and connected it again. That fixed it 🤷‍♂️
