PLCBUS is Okay

While working on my PLCBUS driver a couple of days ago, i was again very pleased with how it all works.
Reliability is 100% till now. I’ve got 7 plugin modules working for a period of 3 months now and none of them has failed yet. And
it’s fast…getting back a ACK from the module itself in something like
500 ms is one of the main advantages of PLCBUS i would say.

Here’s a small snippet from my logs;the first number on every line is in milliseconds, so as you can see the time from the click of a button from within my HA application untill the ACK comes back from the module, takes only 516 ms:

The nice thing is that you can be sure that the actions that you wanted to take place, did take place. And that confirmation comes in half a second. I can live with that, for now :-)

I hope i’ll have some spare time in the next few weeks to try out some more ‘exotic’ PLCBUS modules, like an IR transmitter, a filter, a transceiver and a signal/noise meter.
