Geen DHT22 meetwaarden in beeld

Titel:  Geen DHT22 meetwaarden in beeld

Gisteren mijn DHT22 sensoren ontvangen uit China.
Vandaag gelijk aan de slag...

De DHT22 sensor aangesloten op Wired-out 1 van de Nodo Mega WebApp (Nodo 1).
In het config 01 bestand de volgende aanpassing gedaan:
// DHTRead : DHT22 temperatuur en luchtvochtigheid sensor
#define PLUGIN_006
#define PLUGIN_006_CORE 22

De volgende script ingelezen:
EventlistWrite; Boot 1; TimerSet 1,120
EventlistWrite; Timer 1; TimerSet 1,120
EventlistWrite; Timer 1; DHTRead 1,3
EventlistWrite; WildCard All,Variable,0; EventSend HTTP

Dit krijg ik te zien in de seriële monitor:
Input=Eventlist(1.2); Unit=1; Event=TimerSet 1,120
Input=Eventlist(1.3); Unit=1; Event=DHTRead 1,3
Input=System; Unit=1; Event=Message 14,6: Plugin returned an error.
Output=HTTP(185.10.51.106); Unit=1; Event=Message 14,6: Plugin returned an error.
Output=RF; Unit=0; Event=Message 14,6: Plugin returned an error.

Geen meetwaarden.
Bij een Dallas sensor op Wired-out 1 krijg ik wel meetwaarden van de Dallas sensor te zien. Dus de Wired-out 1 poort werkt wel goed. Het aansluiten van de DHT 22 sensor op een andere Wired-out poort geeft ook geen resultaat.
Ik heb de DHT22 sensor getest op een andere Mega met een sketch (DHTtester) gedownload van internet. Dan komen de temperatuur en luchtvochtigheid wel in beeld.
Het toevoegen van een weerstand van 10 kOhm tussende Vcc en Data pin geeft geen verbetering.

Wat gaat hier verkeerd?

Typ in commands is:

status plugin...

Als je plugins ziet verschijnen zijn de plugins goed mee gecompileerd

Titel:  Re: Geen DHT22 meetwaarden in beeld

Dit krijg ik in de WebApp te zien als ik bij Commands "Status plugin" intype:
Input=HTTP(185.10.48.55); Unit=1; Event=Status Plugin,0
Plugin 1
Plugin 2
Plugin 5
Plugin 6
Plugin 21

In de seriële monitor nog geen meetwaarden:
Input=Eventlist(1.2); Unit=1; Event=TimerSet 1,120
Input=Eventlist(1.3); Unit=1; Event=DHTRead 1,3
Input=Clock; Unit=1; Event=Timer 1
Input=Eventlist(1.2); Unit=1; Event=TimerSet 1,120
Input=Eventlist(1.3); Unit=1; Event=DHTRead 1,3

Volgens mij moet je de sensor niet op de wired out, maar op de wired in aansluiten.....

Weet het niet geheel zeker... :?:

Wiredout is goed. Zie wiki.

Je hebt he;lemaal gelijk :oops: ... Had mijn eigen situatie hier eens bekeken en heb de aansluiting van de LDR met de aansluiting van de DHT verward.....

excuses :oops: :oops: :oops: :oops:

Wie, o wie kan mij verder helpen? :?

De bedrading van de DHT22 sensor naar de Nodo Mega WebApp nagelopen. Alles zit goed aangesloten en toch krijg ik geen meetwaarden te zien.

Input=Clock; Unit=1; Event=Timer 1
Input=Eventlist(1.2); Unit=1; Event=TimerSet 1,120
Input=Eventlist(1.3); Unit=1; Event=DHTRead 1,3
Input=Clock; Unit=1; Event=Timer 1
Input=Eventlist(1.2); Unit=1; Event=TimerSet 1,120
Input=Eventlist(1.3); Unit=1; Event=DHTRead 1,3

De Mega opnieuw compileren geprobeerd? Met de laatste versie software?

Dat heb ik allemaal gedaan.
Nodo-Mega V3.7, Product=SWACNC-MEGA-R744

Als je in de serial DHTRead 1,3 intypt, ook een error?
