(typeof event.delta.apower !== "undefined" ERROR

[OlivierD]

Hi, 

 

I have a crash error with this very simple program:

 

function production (event, user_data) {
  print(JSON.stringify(event)); 
  if (typeof event.delta.apower !== "undefined") {
    print("coucou");
  }
}

Shelly.addStatusHandler(production, null);

 

 

{"component":"switch:0","name":"switch","id":0,"delta":{"id":0,"apower":0,"current":0,"output":false,"pf":0,"source":"WS_in"}}
coucou
Uncaught SyntaxError: Got class expected EOF
at class||class||}
^
in function called from system

 

 

I dont understand the problem.

Why not:

 if ( event.delta.apower !== undefined ) {

I have tried the original version of the Scrip on a Pro 3EM - it just works, i.e. at least there is no error message like yours.

Which Shelly device are you experiencing the error with? Is the firmware up to date, i.e. 1.4.0? @OlivierD

I have adapted the script to the properties of my Pro 3EM:

function production (event, user_data) {
  print(JSON.stringify(event));
  print("value : " + event.delta.total_aprt_power);
  if (typeof event.delta.total_aprt_power !== "undefined") {
    print("coucou");
  }
}

Shelly.addStatusHandler(production, null);

Result:

{"component":"script:1","name":"script","id":1,"delta":{"id":1,"running":true}}
value : undefined
{"component":"em:0","name":"em","id":0,"delta":{"id":0,"a_act_power":-3411.3,"a_aprt_power":3418.4,"a_current":14.102,"a_freq":50,"a_pf":1,"a_voltage":242,"b_act_power":-3240.8,"b_aprt_power":3244.6,"b_current":13.587,"b_freq":50,"b_pf":1,"b_voltage":238.4,"c_act_power":-3152.6,"c_aprt_power":3163.9,"c_current":13.171,"c_freq":50,"c_pf":1,"c_voltage":240,"n_current":null,"total_act_power":-9804.665,"total_aprt_power":9826.854,"total_current":40.86}}

if ( event.delta.total_aprt_power !== undefined ) {

@mschaeffler suggestion also works.
