mqtt update sending all the time

From Cumulus MX version 3 build 3044 the development baton passed to Mark Crossley. Mark has been responsible for all the Builds since, and has recently released Cumulus MX version 4. He has made the code available on GitHub. It is Mark's hope that others will join in this development, but at the very least he welcomes your ideas for future developments (see Cumulus MX Development suggestions).

mqtt update sending all the time

Post by GSV3MiaC »

I just updated to 4063, because I thought this had been fixed since my old version, but apparently not. If I ask for mqtt messages 'on update' I am getting one every 2 oe 3 seconds, although the data being sent has not changed. See:

(Ok it says 'interval' because I am using the same mask to receive the values the other end).

This is with a Davis Vue, and a very old data logger.

It is this:

{"topics":[
{
"topic": "CumulusMX/Interval",
"data": "{\"temp\":<#temp>,\"humidity\":<#hum>,\"windspeed\":<#wspeed>,\"rainrate\":<#rrate>,\"dayrain\":<#rfall>,\"press\":<#press>,\"intemp\":<#intemp>,\"inhum\":<#inhum>}",
"retain": false
}
]}

which is what I have used for the interval updates since forever. none of the references values seem to change between one mqtt post and the next.

Try adding "doNottriggerOnTags"

Code: Select all

{
    "topics": [
        {
            "topic": "CumulusMX/Interval",
            "data": "{\"temp\":<#temp>,\"humidity\":<#hum>,\"windspeed\":<#wspeed>,\"rainrate\":<#rrate>,\"dayrain\":<#rfall>,\"press\":<#press>,\"intemp\":<#intemp>,\"inhum\":<#inhum>}",
            "retain": false,
            "doNotTriggerOnTags": ""
        }
    ]
}
