The problem is I run an VP2pro and want' to use a service to only get
the lightning data, not inTemp, barometer which are provided too and
woul normaly map to the values which are reserved by the VP2pro.
As MQTTsubscribe works great here for 3 other sensors I would prefer
this way to map only the lightning data into weeewx.
I changeded to posted config of vinve withe ignore = true in the head of
the config section, but even no success:

OK, lets start with changing keyword_delimeter = “&” to keyword_separator =
“&” and see what errors that gives.

Jeesh, its amazing what ‘people’ will ‘stuff’ into an MQTT message….
The ‘header information’ (POST, HOST, etc.) is making ‘invalid keyword’
data for MQTTSubsribe. It’s obviously not json….
It’s gonna’ take a bit of work to figure out how to best parse this.

Hi all,
I just tried to integrate a lightning sensor attached to the GW1200
Gateway into weewx with MQTTSubscribe
<https://github.com/bellrichm/WeeWX-MQTTSubscribe/blob/master/bin/user/MQTTSubscribe.py>
.
I enablede MQTT in the GW1200 but I struggle to get the data parsed.
The problem seems to be this added header in the MQTT message..?!
Any chance to get it working I didn't find a solution.
The MQTT message from the GW1200:
POST /data/ip_api/ HTTP/1.1

Any help would be appreciated.
Maybe bellrichm could give some hints to get it working...!?
Thanks in advance!

Just a quick update - the GW1200 with latest V1.4.0 firmware now
supports posting to MQTT too.
I enabled it for a quick test and poked around a little with
mosquitto_sub to look at what it sends and it looks like the same data
elements that I'm getting for Gary's legacy GW1000 driver plus one
additional element "srain_piezo" which we neglected to make known to his
driver last year when I was working with him to support the WS85. My best
guess is that it means "state of raining (or not) on the piezo sensor"
where 0 = not raining, 1 = raining.
Upside is you can set MQTT to send data as frequently as every 10
seconds. Downside is the sensors don't send data that often so kinda why
bother running faster than maybe every 30 seconds.
Re: the use of & my guess is this is WU protocol. If you subscribe to
topic_name/# you see a header ala:
POST /data/ip_api/ HTTP/1.1
HOST: cdnrtpdate.ecowitt.net
Connection: Close
Content-Type: application/x-www-form-urlencoded
Content-Length: 925
I have never configured my gateway to talk to ecowitt, so I don't know
if it's actually trying to post data to ecowitt's servers (or not), but it
sure looks fishy to me.

That sounds like a great "work around" for some who use WeeWX. But I
really wish the underlying issue of using a non standard separator,
which does not comply with the published MQTT standard.could be addressed
and fixed.* Design a device that offers to publish to a MQTT server,
make it standard compliant* , so that it will be easy to subscribe to
that topic on a wide range of MQTT clients.
