MQTT for rules on INA219 gives an error

[costo]

Hi,

I'm using firmware version mega-20231013 and have a INA219 connected.
I want to use MQTT and sent data to domoticz and only use one task, so I use rules.

If I use MQTT, I get Error: MQTT: Invalid/Unhandled data received! (Topic: domoticz/in, Message: ("idx":20x)
for all 3 devices

Code: Select all

on INA219#V do
  Publish domoticz/in,{"idx":207,"nvalue":0,"svalue":"[INA219#V]"}
endon

on INA219#A do
  Publish domoticz/in,{"idx":208,"nvalue":0,"svalue":"[INA219#A]"}
endon

On INA219#W Do
  Publish domoticz/in,("idx":209,"nvalue":0,"svalue":"[INA219#W]")
endon

If I use the HTTP method it works, no error and devices get updated.

Code: Select all

on INA219#V do
  SendToHTTP 192.168.178.202,8080,/json.htm?type=command&param=udevice&idx=207&nvalue=0&svalue=[INA219#V]
endon

on INA219#A do
  SendToHTTP 192.168.178.202,8080,/json.htm?type=command&param=udevice&idx=208&nvalue=0&svalue=[INA219#A] 
endon

on INA219#W do
  SendToHTTP 192.168.178.202,8080,/json.htm?type=command&param=udevice&idx=209&nvalue=0&svalue=[INA219#W]
endon

What is wrong with the MQTT rule that I copied from the wiki tutorial on rules.

[Andrew Mamohin]

May be:

Code: Select all

Publish domoticz/in,'{"idx":207,"nvalue":0,"svalue":"[INA219#V]"}'

[TD-er]

Yep, you have comma's in your argument, which is a command argument separator.
So you must wrap the argument in quotes of a type which will not occur in your argument.
There are 3 types of quotes:

Code: Select all

`...`
'...'
"..."

So you can pick a quote to wrap the argument which is not being used in the argument itself, as suggested by Andrew

Thank you Andrew, your suggestion with the quotes did the trick.

Thank you TD-er for explaining this in detail.

I suggest this is to be changed in the example in the wiki over here:

https://www.letscontrolit.com/wiki/inde ... th_own_IDX

there are no quotes around the MQTT example, that's why it ended up in this post

The Wiki is very outdated, more up to date documentation can be found in ReadTheDocs.

The Wiki is very outdated, more up to date documentation can be found in ReadTheDocs.

When looking at: https://espeasy.readthedocs.io/en/lates ... Rules.html
I see under the sub: Custom reports to Domoticz with own IDX

Code: Select all

MQTT

on INA219#Amps do
 Publish domoticz/in,{"idx":123456,"nvalue":0,"svalue":"%eventvalue1%"} //Own made up IDX 123456
endon

on INA219#Watts do
 Publish domoticz/in,{"idx":654321,"nvalue":0,"svalue":"%eventvalue1%"} //Own made up IDX 654321
endon

Also here no quotes around the argument.
For future reference , someone with editing rights, can change this ?

I'll put that on my todo list, at some interval, a checkup on parts of the docs is needed indeed

On INA219#W Do
Publish domoticz/in,("idx":209,"nvalue":0,"svalue":"[INA219#W]")
endon[/code]

Looks like there is a typo here. The 'on' should be in lower case.

Code: Select all

on INA219#W do
  Publish domoticz/in,{"idx":209,"nvalue":0,"svalue":"[INA219#W]"}
endon

No, that doesn't matter, the script statements are handled case-insensitive. You should have found that in your searches for this answer...
