Calculate : unknown token ---- integer conversion

[BartSr]

Problem:

Power-indicator in Domoticz shows sometimes very, very high value (peak)
Somewhere I read this may be caused by not publishing an integer value
I tried to do a rule like this but logfile shows: calculate : unknown token

logEntry shows [Power#W] = 26

if [Power#W] < '1500' then
Publish domoticz/in, '{"idx":1010, "svalue":[Power#W]}'
endif

But in fact the problem might be solved by converting [Power#W] into an integer.
In digged into the docs but couldnot find a conversion function e.g. INT([Power#W]). Does such exists?

What might be a solution?

You can store it in a variable and then access that variable via [int#N] where N is the variable number.

Like this:

Code: Select all

let,1,[Power#W]
Publish domoticz/in, '{"idx":1010, "svalue":[int#1]}'

[TD-er]

By the way, not sure if Domoticz expects quotes around the "svalue" element as the svalue is intendes as "string value".
So maybe you need to wrap "" around the [int#1]

Code: Select all

Publish domoticz/in, '{"idx":1010, "svalue":"[int#1]"}'

Problem:
...
if [Power#W] < '1500' then

Don't try to use strings in ESPEasy rules calculations (comparisons are also calculated), that won't work.

[BartSr]

TD-er, indeed. Quotes are required.

Publish domoticz/in, '{"idx":1010, "svalue":"[int#1]"}'
Thanks!

Ath,

As log showed value 26 I did not realize this might be a string-value.
But if I want to do calculation within rules, can I convert [Power#W] into numeric?

ESPEasy always uses numeric values internally, the concept of strings is only used for (log) messages, displays and sending url's to external systems, etc. You can't assign/store a string value in an internal variable (yet).

Your use of '1500' in that comparison is causing the "calculate : unknown token" error message.

[BartSr]

Ath,

So if I understand you well this is expected to be OK?

Code: Select all

if [Power#W] < 1500 then
Publish domoticz/in, '{"idx":1010, "svalue":"[Power#W]"}'
endif

But it throws same "calculate : unknown token" error

[chromo23]

get rid of the "then"

[TD-er]

What is the value of [Power#W] ?
Maybe you should log this first to see whether it is a numerical value or something like "NaN".

Code: Select all

logentry,"Checking Power#W : [Power#W]"

[TD-er]

get rid of the "then"

And of course... the good old "oops missed that one too"

And of course... the good old "oops missed that one too"

Jep, sometimes all this syntax stuff gets confusing..

[BartSr]

@chromo23
sure, that's it... (mixed up Domoticz dzVent syntax)

@ TD-er and/or Ath
for this case not important but if I want to calculate with e.g. temperatures :is there a way to check a value not being NaN or should I just set the option of error value to -127 and checking for == not -127 first?

[Ath]

You might want to have a look at these operators first: https://espeasy.readthedocs.io/en/lates ... y-function

[BartSr]

Ath, sure I didnot use the correct syntax for the 'equals, not equals, greater then etc'. But most important is how to validate the sensor data.
