So maybe the perfect solution is MQTT with a backfill process built in?
Uncertain. Some folks might not want to run a MQTT broker although it's
easy and lightweight on Linux.
Ecowitt uses so many formats and naming conventions that it's difficult to
suggest what the best path forward might be. I certainly find the MQTT
easier to read and should be far easier to program to (for me at least)
since we already have the nice MQTTSubscribe driver/extension that can
handle the annoyances in how Ecowitt returns the MQTT data.
Re: content.....
MQTT seems more current than the HTTP API data for my gw1200 running latest
firmware that came out recently:
- MQTT has additional info missing from HTTP (vpd, soil moisture ADC
value, gateway model, gateway freq)
- MQTT and HTTP report battery levels much differently it seems
- MQTT makes absolute and relative pressure easily both available, HTTP
has an item that 'seems' to be the offset in kPa (?)
- HTTP structure for how it reports rain is just odd. They have
hardware info in the same element as the yearly rain totals
- HTTP is also odd in their model identifiers. My gw1200 inside
temp/hum/pressure info comes up as being from a wh25 (!!!!)
- getting HTTP data can mean dealing with that horrid "page=N" thing and
assembling things from multiple pages of data
- http://x.x.x.x/get_sensors_info?page=1
- http://x.x.x.x/get_sensors_info?page=2
- then assembling them in some order based on type id value
That said....Ecowitt MQTT isn't perfect either
- sensor RSSI and 'signal' (whatever that is) is only available via HTTP
get_sensors_info if that matters to you
- and MQTT returns a HTTP POST header and multiple blank lines, using WU
protocol formatting with & rather than , as the delimeter, but folks have
already reported and worked that issue here with how to set up
MQTTSubscribe to deal with that annoyance so while it's ugly it's easy to
work around
I'll attach a txt file with the data I see here with a little light editing
to make it easier to go through.....
