Hello,
I'm running a RAK7244 LoRaWAN server/gateway on a local network to which my
weewx server is connected. Weeex is the latest stable on Ubuntu with
extended db.
A CO2 sensor is sending data to the LoRa server. I have node-red on my
weewx server with a flow connecting to the RAK7244. I want to have the CO2
data put into the co2 slot that is available on the weewx db.
I have installed the weewx extension Mosquitto-subscribe and attempted to
configure weewx.conf as:
#################################################
# Options for 'MQTTSubscribeService'
[MQTTSubscribeService]
# This section is for the MQTTSubscribe service.
# Turn the service on and off.
# Default is: true
# Only used by the service.
enable = true # false
# The MQTT server.
# Default is localhost.
host = localhost #192.168.1.10 #localhost
# The port to connect to.
# Default is 1883.
port = 1883
# Maximum period in seconds allowed between communications with the
broker.
# Default is 60.
keepalive = 60
# username for broker authentication.
# Default is None.
username = None
# password for broker authentication.
# Default is None.
password = None
# The binding, loop or archive.
# Default is: loop
# Only used by the service.
binding = loop
# The message handler to use
[[message_callback]]
# The format of the MQTT payload.
# Currently support: individual, json, keyword
# Must be specified.
type = json #REPLACE_ME
# The application/18/device/2cf7f12122500013/rx topics to subscribe to.
[[topics]]
# Units for MQTT payloads without unit value.
# Valid values: US, METRIC, METRICWX
# Default is: US
unit_system = US
[[[first/topic]]]
#value sent from RAK7244
[[[[CO2_Value_PPM]]]]
#weewx db name
name = co2
ignore = false
contains total = True
conversion type = float
#[[[SECOND/REPLACE_ME]]]
################################################
The message (data) every 60 minutes coming from the node-red function is:
{"CO2_Value_PPM":401}
I may have too many things going here but, as I'm not a programmer, I'm
stuck trying to figure out the problem. The node-red flow is connected on
both ends (RAK7244-->weewx) but I don't see any data reaching the db.
Thanks in advance if anyone can help on this.
Cheers'
Bob
