Hello, I have the problem. Till yesterday I had my TUYA sensors connected to the other router without Deco M4. Yesterday I changed the router and installed deco M4 three devices. From yestarday my tuyas do not work. I have tried with 2,4GHz only with 2,4GHz and 5 GHz nothing. I noticed that the TUYAs are acctive only when I am very close to them probably they connect with bluetooth. I have 10 TUYAS in windows to control the curtains. When I get close to the tuya it is working, when I go to another the last one stops working and the closest one is working.

I have M4 as AP, M4 connected LAN via switch to LTE router with static IP. In the router wifi is switched off. Can You please suggest sth bc my wife is getting crazy :)

Thank You for Your help. Hubert
