Hi,
Wow, my first post in an empty board...

First, let me introduce myself. I started with Home Automation/Domotica 5 years ago; started with Homeseer, 1-Wire, X10, X10 RF etc. but I replaced X10 with PLCBUS before I had too much of that, and I'm still glad I chose PLCBUS over X10. Well we all know the advantages, don't we :-)
And I decided to create my own Home Automation system in a way that I think it should work; that's about 4 years ago now.
Currently I have 3 X10 modules left in my house and over the last 2 years the number of PLCBUS modules has grown to 18.
Currently I'm replacing all the X10 MS13 motion sensors cause I don't like those anymore either.

I've written my own PLCBUS driver for my homemade Home Automation system somewhere in 2008 and it's all working ok.
However, there's one thing I would like but what I never got working, and that's the Get Noise Strength command (19).
Since it's not really essential I just let it be, OTOH it's always nice if the driver is complete...

Does anyone have a tip, hint to get Noise Strength working?

Thanks!

PS.
It's good to see a forum devoted to PLCBUS, keep up the good work!

Hi Digit,

welcome to PLC-BUS.info.

GET SIGNAL STRENGTH
GET NOISE STRENGTH

Both follow the same command structure as STATUS REQ!

Sending command without ACK-request
Receive bus echo
Receive answer as command REPORT SIGNAL STRENGTH or REPORT NOISE STRENGTH

Here RX/TX communication from homeVisu RX/TX-monitor at 1 phase.

GET SIGNAL STRNGTH
Code:
09:34:01,984 - TX: 02 05 FF 00 18 00 00 03    <- GET SIGNAL STRENGTH
09:34:02,406 - RX: 02 06 FF 00 18 00 00 1C C5 <- bus echo
09:34:02,828 - RX: 02 06 FF 00 1A 1E 00 0C B5 <- REPORT SIGNAL STRENGTH

GET NOISE STRENGTH
Code:
09:34:34,140 - TX: 02 05 FF 00 19 00 00 03    <- GET NOISE STRENGTH
09:34:34,578 - RX: 02 06 FF 00 19 00 00 1C C4 <- bus echo
09:34:35,000 - RX: 02 06 FF 00 1B 00 00 0C D2 <- REPORT NOISE STRENGTH
