As I posted in another thread about a stuck firmware update (which finally completed), One of my Shelly 1 devices struggles to stay connected to WiFi. I also have an Asus Mesh router system and I tried binding the device to each of the nodes, or just letting it auto-roam. Nothing seems to help it stay connected for more than a few hours.
Are there any settings to tweak on the Shelly device within the Internet configuration?
