Luc,
you were right in many respects.
I had some success, yet not with tfrec. It always renders "BAD" instead of
temperature or humidity. I changed trigger value and gain a lot but found
no set of parameters that worked. I ordered another but different SDR stick
and we'll see whether hardware was the root cause.
Following your other advice I indeed installed weewx with your klimalogg
driver and it worked as designed. Then I added to your routine
genLoopPackets the code to put the data into mosquitto:
def pub(packet):
tags = {"temp":"temperature", "humidity":"humidity",
"batteryStatus":"battery"}
for tag in tags:
for i in range(10):
key = "%s%d" % (tag, i)
if key in packet and not (packet[key] is None):
topic = "klimalogg/%d/%s" % (i, tags[tag])
payload = packet[key]
publish.single(topic, payload, hostname="localhost")
null = None
this was easily catched by openhabian (standard mqtt binding). Yet only
works for the current value. I am struggling a bit with storage and
presentation (grafana). All was new to me: openhab, weewx, grafana, SDR.
I also need to put your kl.py into debug mode one day to understand the
sequence in which weewx invokes the routines.
For the time being I just wanted to let you know.
regards,
Walter
