Tuicemen, I want to thank you for the great software! I've been an X10 user for decades now and recently got an Amazon Echo, Dot and Ecobee4 thermostat and wondered how difficult it would be to add voice automation to all my various X10 devices and was excited to discover your Alex10 software. I just picked up a CM19A from eBay and received it today (I have an ActiveHome CM15A that I use for timers, but it isn't near my computer and is in a strategic location such that all my X10 devices that use timers will respond). I got everything going tonight. I noticed that my devices will work with either the PLC or RF setup. It seems that I would need to use the RF setup since the CM19A is USB to wireless, but maybe I simply don't understand what that setting is for. A couple of other things I noticed is that whenever I add a device, a popup tells me that the bridge is not running. But I just add the device and start the bridge each time and it works like a charm. Finally, I couldn't get Echo to recognize any of the devices --- until I saw in an earlier post saying that if you define a port on the bridge, Alexa won't communicate (Makes sense when you think about it). Sure enough, I took the port off the IP address and it picked up everything right away! I was so excited! Thanks again for all the hard work on this ...
