hi, i have problem with reads of temp data. I use rf433 sensor sometimes it sends bad data -67C :confused: to read it i use JSONPATH:$.message.temperature is there a way to ignore data string if it sends -67 ? and just leave actual data ?

[image] [SOLVED] MQTT: How to filter implausible values on channel? Bindings Are these reported as just numbers or encoded in JOSN or XML or some other way? If they are just numbers you can use a JS transformation and return “UNDEF” if it’s out of range. UNDEF…

i’m to new in this :frowning: so if i go to scripts and paste that on web panel, in my thing channel i have: Type number : digoo_temp [ stateTopic=“home/OpenMQTTGateway/PilighttoMQTT”,transformationPattern=“JSONPATH:$.message.temperature”] i should add somewhere temp.js if i create one via web pa…

You can’t create the javascript file via web panel. You need to make a traditional file and place it in your /transform folder. You will need to install the JS javascript transformation add-on. Then, because you happen to use MQTT binding, you can chain your new JS transform after your existing JS…

thx so something like that : [ stateTopic=“home/OpenMQTTGateway/PilighttoMQTT”,transformationPattern=“JSONPATH:$.message.temperature∩temp.js"]

No. Like you did with your JSONPATH, you first have to say what kind of transformation to use. In this case, JS. Right idea though.

ok i fith i known now : stateTopic=“home/OpenMQTTGateway/PilighttoMQTT”,transformationPattern=“JSONPATH:$.message.temperature ∩ JS:temp.js"]

so i have a file transform\temp.js: (function(i) { var val = parseFloat(i); if (val >= 100 || val <= -60 ) { return ‘UNDEF’; } else { return val; } })(input) and channel : Type number : digoo_temp [ stateTopic=“home/OpenMQTTGateway2/PilighttoMQTT”,transformationPattern=“JSONPATH:$.message.t…

Do you ever see UNDEF? What do your logs say about it? val looks suspiciously like a keyword to me, don’t know if it is or if it matters.

Its my first time just use a script from 2nd post. But i think script isn’t used like it should be on lof file i found : transformation service JS for patten temp.js not found. I think the space is a problem just dont know it should be temperature ∩JS:temp.js or temperature∩JS:temp.js i have to try …
