İf google fails, do you still need an internet connection to reach tapo switch? If tapo requires cloud access, you might switch to some other local solutions as zigbee or zwave
I am testing ping now , just wait until HA restart .
If you are asking if your lan devices will be in a mess if the internet goes down then the answer
is yes and no based on your devices and setup . The clouds ones for sure will have problems if the outage is taking a long time .
I will try to test but It could be different in your case
I SURE love to work together.
ANd defo share my outcomes with the forum.
I just need 2 or 3 days to setup everything and receive some extra HW I got from Amazon
This is very important, I will need some testing.
I dunno if TAPO would work despite an outage, but it does not matter, I can just buy another Smart Switch or use another one I have at home.
That is really easy , i will do test to power on a device on the lan based on the ping result . but I will test only LAN device , I can not disconnect the WAN now because there are a lot user and devices
What i am also interested in is actually to find if the connection is slow or not ( like a speed test below )
Because I do not expect WAN to face frequent issues ( If your WAN is facing lots of issues then that needs to be fixed on its own ) .
Nowadays with working from home and distant learning if your WAN disconnects for any reason then raise hell with your ISP . I have changed ISP because of one disconnection and now I cant recall when was the last time I faced WAN outage ( i faced power outage only )
Lecture finished
Now for the issue at hand …
Try the speedtest integration above , it has ping and more . this is all we need to monitor the WAN performance and not only connectivity
If you need few days to setup things then lets talk then because we will customize it to your setup .
There is a concern beyond the WAN outage, the entire house automation and security has 2 single points of failure that can be exploited by burglars or even worse:
Fisically cutting the fiber cable, it runs unprotected on the side of the house
Cutting the power.
The former weaknesses is remedied by the LTE failover of the router, it is a LBR20 with 4G sim
The latter is corrected by having all home smart hubs, the router, the RPi4 attached to a UPS APC with apcupsd running.
