MQTT - Min/Max values ?

[Andy Hudson-Smith]

Just wondering if its possible to add Min/Max tags for the day to topics - so Min / Max temperature etc.

It would mean i could use MQTT for all my outputs, rather than just the current live ones.. i have had a look and cant work out if its possible,

Hope thats ok to ask,

Andy

hi

i´m looking for the same, but didnt find any solution.

I´m coming from meteohub where all this datas are there and i parsed to iobroker.

Now im sending via mqtt from weewx to iobroker but im missing also a lot of min / max values.

Is there any solution ??

It's unclear what you are trying to do or what you think is 'missing'.

Do you want to have MQTT publish min/max values as well as observations ?

 

If so, you probably need to write some kind of custom extension to periodically capture the min/max values you are looking for and publish them separately to your MQTT broker.

As I understood the question, people wants to send some aggregations additionally to the observations to the MQTT broker, similar to the tags in skins, where you can write $current.outTemp and $day.outTemp.max. The same applies to images where you can set aggregate_type and aggregate_interval together with the observation type. Contrary to that, in MQTT section you can set observation types only.

Actually I see no solution besides sending a PR to the MQTT extension author.

Yes - if you can't find it, you have to write it yourself (and hopefully contribute a PR so the next person doesn't have to write it too).

I made a workbaround by getting the min/max/trend via a json file and republishing to MQTT alongside the main feed - github if it helps at https://github.com/digitalurban/mqttweewxhtml
