Format error

Emoncms
1

I have quite a lot of the following errors in my emoncms.log

2016-05-31 18:34:46.837|ERROR|input_controller.php|Format error, json value is not numeric

Looks like something is posting data that’s not formatted totally right??

Doesn’t seem to hurt anything though…
Can i find what is posting these errors? node number at least?

Greetings,

Could you give us some more info as to how and what you are posting to Emoncms?

Most of them are node-red instances at various locations posting with the emoncms node.
They are posting data this way:

return {payload: "Afvoertemp.:"+ msg.Tafvoer + "," + "Toevoertemp:" + msg.Ttoevoer + "," + "Retourtemp:" + msg.Tretour + "," + "Buitentemp:" + msg.Tbuiten};

I have one python script posting to my emoncms.

conn.request("GET", "/""input/post.json?apikey="+apikey2+"&node="+str(nodeid)+"&json={Boilertemp:"+str(Value1)+",AanvoerSTE:"+str(Value2)+",RetourSTE$
response = conn.getresponse()

Maybe a format error in my python script line?

Can i find out what ip the error’s are coming from?

Thx!

I am having the same errors come up in my log running emoncms on ubuntu 16.04

I am posting from an EmonPi on a local network ie EmonPi has direct access to the emoncms server.

I seem to getting all the feeds ok so not sure if this is a real problem or not.

Looks to be being generated by the EmonPi, found this in the EmonHub Log:

By default the “emonpi” variant of emonhub sends every 30secs whether there is data or not, the empty data-[] should not be sent and emoncms could be a little more informative and say it has received no data rather than it was not valid. But as annoying as it is, it will not cause you a problem as it is not a “fault” per se.

I see you have altered the send interval to 3secs so you will see more occurances than most users.

Thanks for feedback.

Didn’t think there was a problem as it seems to be working fine.

I have since moved to 10 seconds as per recommendations .

I’m seeing this error too.
