xapmcsRF - W800 / RFXCOM xAP Node

[Michael McSharry]

It looks to me as if the scale is reporting 136.4 kg. What do you expect?

There is also a message that is 56 bits long which does not comply with the other scale's decoding format and was rejected. Do you have a second type of scale?

38, 1A, 2D, 10, 0D, 30, 25
19:16:48 | 20 | OSScale ignored because checks digits do not match

for help :

K = 138.4 =>> = 62.6kg ??
K = 138.2 =>> 62.7 ??

Everything is good!

This works

138.4lb X 453.592 / 1000 = 62.77kg
or
138.2lb X 453.592 / 1000 = 62.69kg

Thank you very much!

I had confused the units.

It remains to decode the fat and water, we'll work on it.

I believe you will find your xapmcsRF settings set to produce english rather than metric units. The value shown is in units of lbs.

This is not the correct logical formula....
I think that we have found the correct formula for weight....
<code>(decimal packet value) * 163.5 / 65535</code>

and also we found the octet that are used to transmit the resitance to compute the %water and so to get %fat.. and the formula to used to do that.

All is explain in this english post :

As you are french, you should join us on this forum post where we are discuting about the GR101:

For information, a google spreadshhet is used to get some diferent packet from different user :

RFXCom Transmitter support

Hello Michael,

I'm a long-time xapmcsRF user with a Visonic RFXCOM receiver.

I've now invested in an RFXCOM 434mhz Transmitter, does your application support Transmitters?

If so, are there any examples of how to send commands?


Thanks,

Martyn

[Michael McSharry]

I have never looked into the transmitters

[martynw]

Ok, thanks anyway, I noticed that there was a setting for a com port for "Transmitter" on the web interface and hoped it would be possible.....

WTGR800 and THWR800 not seen

Hi,

i have a WTGR800 wind and temp ane an THWR800 pool thermometer seen by RFXCOM but not by XapMCSRF.
All other modules even UV are working all right.
i attached a file with RFXCOM log and XapMCSRF log.

regards
Claude

[Michael McSharry]

Bert will need to provide an update to the decoding document that includes the WTGR800 and THWR800

[bachelet claude]

I asked Bert to send you the file.

browser / xap not working

Hello Michael,

Long time user of mcsrf, I've been using version 1.51 with an rfxcom visonic receiver (868mhz) firmware version 82.

I've been trying to move to the latest version of mcsrf but can't seem to get it to work.

I'm receiving correct data in the IO window such as:

<CODE>
12:51:29 | BA, E4, 8C, 73 | BAE4=S0Off
12:51:36 | 7B, E0, 04, FB | 7BE0=S1On
12:51:46 | 2E, 10, 84, 7B | 2E10=S1Off
12:52:44 | 48, A9, 84, 7B | 48A9=S1Off
12:53:17 | 41, 2B, 84, 7B | 412B=S1Off
12:54:10 | F5, AB, 8C, 73 | F5AB=S0Off
12:54:16 | 6B, 9B, 8C, 73 | 6B9B=S0Off
12:54:19 | 33, 31, 84, 7B | 3331=S1Off
</CODE>

But I don't get anything updated in the web browser nor over xAP.

Did anything change in versions after 1.51 that would cause this?

Thanks for your help,

Martyn

The activity has been with the OS sensors, but the decoding is interrelated so anything is possible. Since I do not work on this very often things do not come to memory quickly. I will need to look to follow the logic path.

Claude, Bert did send me his code and he is busy now so not able to update the document. When a get some time I will try to reverse engineer it to make the update.

Hello Michael,

I'm about to order an RFXCom unit from Bert - does your app work with the LAN/WAN versions too - or just USB ?

Also .. just checking is this receive only or transmit too ? I'm hoping to control the HomeEasy plugs/lights I have .

The alternative commercial HS plugin 'RFXCOM' I assume was not written by yourself (?). I'm trying to get both xAP and transmit capability.


cheers Kevin
