Flood.

We have had quite a lot of rain recently, resulting in flooding here. The water didn’t come into the house thankfully, but it was quite a shock and did some damage. Couple of tech things:

sniffer

The flood and cleanup cut the ethernet cable linking the pump house and the house. This cable was used for a collection of cameras from the pumphouse, including to open and close the gate via home assistant. This feel back on a WiFi Bridge, but with lots of packet loss. I set up a sniffer to find the most costly TCP streams and turn them down - for example reducing from having two sources pulling from the cameras to one, then reducing the camera quality. This has not been totally successful - the reduction in quality is noticeable. I will replace the cable when it is dry.

Switch

Somehow water got in to a outside ethernet cable and toasted one switch port. I recrimped the cable, it toasted another port. I ended up finding water at least a foot up the cable, and threw it out.

IR lights

The cameras have infrared lights. I am trying to set up home assistant to turn them on and off easily, and without having to log into each camera in turn. Progress is slow.
