Hi
is it possible to get CumulusMX to get the Transmission signal and Battery voltage strengths from the Davis Console? if so how?
Thanks in advance...

<#txbattery channel=1> This will return a simple 'ok' if the battery level is good for this ISS.
<#battery> This will return the console battery voltage.

Re: Transmission and Battery strength
Thanks for clarifying the Battery value.
So is there no Signal strength value can be gain using CumulusMX? I know Weewx can report on the percentage of ISS Signal Quality, I was just curious as to whether CumulusMX had a similar feature.

Re: Transmission and Battery strength
Cumulus makes all the stats that are available from Davis visible. Others you have to calculate, here is what I do...
Code: Select all
<?php
if ($DavisTotalPacketsReceived == 0 && $DavisTotalPacketsMissed == 0) {
echo '0 %';
} else {
$tot = $DavisTotalPacketsReceived == 0 ? 1 : $DavisTotalPacketsReceived;
echo number_format(($tot / ($tot + $DavisTotalPacketsMissed)) * 100, 1) . ' %';
}
?>

Re: Transmission and Battery strength
I doubt that weewx actually displays what is usually termed signal strength (RSSI - Received Signal Strength Indication) for individual transmitters. It's more likely to be a a reception quality percentage, which is as good a single parameter indicator of signal quality as any and calculated as Mark outlines, but it is not RSSI for individual data packets.Toxic17 wrote:So is there no Signal strength value can be gain using CumulusMX?

RSSI values are available in the standard consoles but are not logged as such and hence not available to downstream software. To see the actual RSSI values you need to be using a receiver that does make RSSI values available to software like the MeteoBridge Pro Red units. (Envoy8X consoles also have the capability to do this in principle, but last time I looked - some time ago admittedly - this hadn't been implemented in the current firmware.)
