6 years ago Okay, without testing it, I see two problems:
1) We don't have "<", but "51.7 > $this_data" should do the job 2) (more serious) We don't have floating (or fixed) point vals, just integers. If you are sure, that you need not more than 1 digit after the '.' you can write the following to convert it to a kind of fixed point:
// Get the integer part setvar $int = csvstr($this_data, 0, ".")
// Get the fraction part (after the "."), if none just 0 setvar $frac = csvstr($this_data, 1, ".") | "0"
// Combine it to 10 the val setvar $fixed_point = 10 $int + substr($frac, 0, 1)
This should convert e.g.: 61.28 to 612 and 62 to 620.
As I said: not tested here, but I think you see the idea...

Martin, First I want to say thank you thank you for such a great bit of software! I am having difficulty with a script I am trying to create, and I cannot figure out how to do it. I receive a value from another MQTT client into this broker. This value is between 40.8 and 59.2. If the value is greater than 54.5 I want to turn on the relay. If the value is less than 51.7 I want to turn off the relay. I get an error when I load the script, I get an error. My script I'm having difficulty with is as follows:
on topic local $Voltage_topic do if $this_data > 54.5 then setvar $relay_status = 1 gpio_out 14 $relay_status gpio_out 13 not ($relay_status) else if $this_data < 51.7 then setvar $relay_status = 0 gpio_out 14 $relay_status gpio_out 13 not ($relay_status) endif endif
Can you please show me what I am not understanding? Thanks in advance! Steve
