Z-UNO to control LG 3 Wire HVAC

Post by DoinitSideways » 16 Oct 2018 05:04

Hi,

maybe someone here could help me with the below???

My experience with vera (zwave) is purely plug and play, I?m hoping someone out there might have a read of this article and be interested in trying to get it to work with vera?? I?m happy to purchase the required hardware and assemble it, but I?m lost with any type of coding know-how... even happy to send a little cash for anyone?s help if we can get this to work??

The original creator Andrew is on board with helping me, but isn’t familiar with z-wave / vera...

If I can add to this, as I believe there is a very low baud transfer rate of 104 which I don't think ZUNO can cope with.
If the baud transfer rate can be solved then it simplies the application.

Z-Uno s/w serial can be extended to this baud rate. But such slow data can also be ruled via digitalWrite directly

Hi PoltoS,

I’ve just ordered my z-uno, when it arrives, would you be willing to help me through setting the baud to 104?

Cheers,
Josh

Is this what you were referring to?

https://z-uno.z-wave.me/Reference/Software-Serial/

It seems the lowest is 1200, not the 104 I’m trying to achieve??? Or will it work with 104 as the parameter???

I have not tested it, but I don't see any reason not to work. Here https://github.com/Z-Wave-Me/Z-Uno-Core ... Serial.cpp baud is used only to calculate bit_time and it fits in the data type size.

Please try it and if it will not work we will check it. Please use a logical analyser if you have one.
