I have multiple Kasa devices including dimmer switches (HS220), regular switches (HS200) and smart bulbs (LB130). Everything has been working well either from the app or via Alexa.
About two weeks ago, I started noticing some switches or bulbs would randomly be offline, or if they were online they would take a long time to activate when prompted. The switches would seemingly restart or reconnect to the wifi at random times judging by the wifi symbol flashing green.
I thought maybe the issue was with Alexa so I removed all the devices from the app and then reconnected but still had an issue.
I then thought perhaps my wifi network being a 2.4 and 5 Ghz dual band was causing issues so created a dedicated 2.4 Ghz network for my smart devices but this did not solve the problem.
I am not having any connectivity problems with any of my other smart devices (Ring, Eufy, August, Alexa, Tuya, geeni, Govee, Mysa, Econet) ONLY with the Kasa devices. No issues with anything else such as PCs, phones, laptops or TVs either. My router is a Asus ZenWiFi AX.
I tried searching online but don't see any other reports of similar behavior.
Any suggestions? I enjoy the Kasa products and do not want to swap everything to a different brand.
