I’m going to try to consolidate a summary of known Kasa smart plug (HS110, HS300, KP115 and KP125) issues plus all the associated specifics, including exact diagnosis and and workarounds, if available. Feel free to add details of your issues and discoveries in the comments below this posting. Please note that so far, most of the issues appear connected with bad behaviors on the part of the smart plugs, not the Sense integration.
|Symptom||Discoveries So Far||Result|
|KP115/KP125 drops off-line every 5 days||KP115 / KP125 briefly becomes a DHCP server and reassigns their own IP address to 192.168.0.1 exactly every 5 days. Many networks seem to tolerate this and reconnect with the plugs, but some don’t. Similar behavior to a soft reset||Diagnosed - File issue with TP-Link Workaround ?|
|HS110s become zombies, drop offline, and are non-reponsive to pings||Did not happen with simple Apple network, but appears on Ubiquiti. Regular pinging of HS110s plus reserved IP addresses seem to help. Could this be related to the same soft-reset like behavior seen with KP115s ?||Investigating - looking for best methods|
|Sense Communication Crashing with Many Kasa Devices Connected||Sense monitor is seeing increased CPU usage because of many smart plugs, Hue devices etc. Support have tweaked the monitor to poll smart plugs less frequently to bring the CPU numbers down and avoid data loss.||Diagnosed and fixed|
|Lost connections to HS110 and/or HS300||A quick off/on toggle of the NDI seems to get them all back online.||Undiagnosed but easy Workaround|
|HS110s pings fail a high % of the time||Failed to respond: HS110 (downstairs) 74% and HS110 (upstairs) 94% of the time, via network extender. Other users experiencing similar.||Investigating - looking for best methods|
|HS300/KP115 trigger false notifications at 5:25AM||Around 5:25AM each and every morning there’s an false off notification followed by a false on notification on a number of devices on HS300/KP115 plugs. It’s not like the never come back. Just disconnected.||Investigating - looking for best methods|
