Current setup, 6 TP Link HS100(plugs), 1 TP Link HS105(Mini plug), 3 HS200(wall switches) and 2 LB120 (light bulbs). Over time the Alexa control does not work stating "the device is not responding". When I check the Kasa app on Android phone, the device will be listed as "Local Only". After a few minutes the "Local Only" will disappear from KASA app and Alexa connectivity to the modules works again. Most of the time if Echo cannot control a device, I am able to use the Kasa app to control it, so appears wifi connectivity to the device is OK , but not the interface from Alexa? A few times after Alexa could not connect to a module, the module would complete the requested action eventually after a few minutes. According to the Kasa app, the best dBm signal I have is 30, most are between 40 and 60 and I have one device at 76(HS100), all within specs for simple on/off switch control.
This is consistently happening, every day, usually in the evening hours after 5p, but is random at best and does happen before noon some days. All of the devices have excellent wifi connectivity on my 2.4g (usually around 300m thruput when testing from the various locations). My 5g is amazing, I can get 700m over the air - I have 1gig fiber internet service.
Attempted Resolution steps:
Recently upgraded wifi router (same issue happened on old router), reset all modules and re added to Kasa and Alexa. Did not resolve
Added static IP address to each device in my router assigned to its own MAC address - did not resolve
Each device running on DHCP - did not resolve
Change IP address lease times - did not resolve
Confirmed Latest firmware on all devices -
Confirmed correct Time Zone on all devices -
Ensured remote control is on in KASA app
Does anyone else have this same issue, know the resolution or have any ideas on what the exact issue is? Is there too many modules running?
