First MQTT Test and wishes + Ideas

Enviroment: Using a mosquitto server on a Raspberry Using a Node Red instance on a other Client SBC

image

IS: BT_DMM/V05B : msg.payload : string[8] " 27:°C:"

Idea to change Payloadformat: (quick idea) Example1: "{ Time: "2022-07-31T17:33:00", BT_DMM: "V05B", Value: "Unit"}" Example1A: "{ Time: "2022-07-31T17:33:00", BT_DMM: "V05B", Value: "Unit", Current: "DC"}" BT_DMM: "CLIENT" Current: "DC" Current: "AC" Diode: ".OL"

Example2+SI. "{ Time: "2022-07-31T17:33:00", BT_DMM: "V05B", Value: "Unit", Value: "SI-Unit"}" Example2 :"{ Time: "2022-07-31T17:33:00", BT_DMM: "V05B", 100.0: "mV", 0.100: "V"}"

Example other MQTT Clients i use:

Tasmota: "{ Time: "2022-07-31T17:33:00", BME280: object, ESP32: object, PressureUnit: "hPa", TempUnit: "C" }"

RTL_433: "{ time: "2022-07-31 16:31:43", model: "GT-WT02", id: 188, channel: 1, battery_ok: 0 … }"

DWD Deutscher Wetterdienst: "{ station: "MUENCHEN STADT", tempc: 26.1, humidity: 35.7, windspeed: 3.8, winddirection: 285.9 … }"

Tasmota2 "{"Time":"2022-07-31T18:42:00","TSL2561":{"Illuminance":428.000,"IR":12080,"Broadband":30864}}"

Own Device: "{"Time":"2022-07-31 18:40:01","BME280":{"Temperature": 26.7,"Pressure":950.9,"Humidity": 43.9},"TempUnit":"C"}"

You are very fast !! +++

I can change format Its not problem but keeping data lenght sort is better for data speed and beware data loss but its no problem. Time? but why. target system can get their clock

ludwich66 commented 2 years ago

Hi Engin,

please change to JSON Format with Key:Value format.

about timestamp: a timestamp is useful to find the right order, MQTT is caching messages if connection is lost or broken. i meen Transfer is’nt 100% in Order.

??? Your Client uses a Timstamp too ??? You didn't do that without reason ;-)

al other formatstrings are examples from „great“ platforms.

I'm looking forward to the revised version. Then I will start a long-term measurement of the transmission quality.

Ok I got it

No.. Its just test clients timer. and I know that you will want time :) thats why I put :)

please change to JSON Format with Key:Value format.

will doo in an hour I think.

BTW Can you do me a favor? I think I have to create wiki for app. and you are beteer than me at this.

ludwich66 commented 2 years ago

BluetoothDMM.zip this should be enough :)

ludwich66 commented 2 years ago

New Test:

Sorry for my false examples before!!

JSON Parsing Error actual JSON string: "{ Time:"31.07.2022 20:56:30",Device:"Bluetooth DMM" ,Value:" 25", Range:"°C", Current:""}" we need more "quotes" and deleting blanks

I mean this works better ;-) "{"Time":"31.07.2022 20:56:30","Device":"Bluetooth DMM","Value":" 25","Range":"°C","Current":""}"

Done :) I left blanks as is but absent keys worse than blanks I think. BluetoothDMM.zip

ludwich66 commented 2 years ago

NodeRed View now its a valid JSON Object

image

I run this night a longperiode test with chart and filesaving on Nodered side V05B --> BTDMM --> MosquittoBroker --> NodeRed-Client --> Filesave

CU tomorrow ludwich

ludwich66 commented 2 years ago

But there is the little problem with string " 25" and Int value 25. hope we can find another way here, you can't calculate with a string...

webspiderteam commented 2 years ago

it has to be float value but if we send it like that u cant get AUTO and NCV but you can easyly convert it if its string. just with 1 line code

ludwich66 commented 2 years ago

Idea send „Value“:1234 —> Float 1234 25.00 and „Display“:“string“ —> Auto .OL „ 25“ etc.

but more tomorrow (sleep a night over ideas first…)
