Weird X10 commands received

Has anyone ever seen anything like the Log file below. Every minute Indigo is receiving some X10 command. I've never used any X10 products. This has been happening for at least a month. I only noticed it because I've been playing around with my Indigo setup for the last week. Does anyone no what can be sending the commands?

I've seen that coming from a couple of failing devices - it wasn't easy tracking them down unfortunately but I finally found them by shutting off circuits one at a time then air-gapping or unplugging the devices on that circuit until I found it.

Ugh...

Sounds like I'll be busy this weekend
