Esp 01 Module met DHT22 waarde Null !!
Problemen met DHT 22 en Esp01 module
Geregeld valt bij deze module de communicatie weg met de DHT22 sensor, deze sensor heeft een Pull-weerstand van 10Kohm nodig om juist te werken
Dit blijkt met Tasmota nog steeds problemen te geven
alles nu op ESP Easy gezet en bolt nu al verschillende dagen zonder problemen.

Tasmota puls uitgang "Rule" maken !
https://eye-vision.homeip.net/tasmota-op-nodemcu-esp8266/
Hier vind je de RULE om een puls uitgang te maken op een ESP tasmota module
Als je het NodeMCU bordje wilt gebruiken als een pulse-schakelaar om bijvoorbeeld je garage te openen/sluiten moet je een rule aanmaken in Tasmota in het ‘Console’ scherm:
Deze rule zorgt ervoor dat indien het relay wordt aangezet er een delay van 0.1 seconden is gevolgd door het weer uitzetten van het relay. Op deze manier genereer je dus een puls.
Regel om uitschakelvertraging te maken voor bewegingssensor
Time-delay After Switch Off~
Rule
Backlog switchmode1 1; rule1 1
Rule1 ON switch1#state=1 DO Backlog Power1 on; ruletimer1 0 ENDON
ON switch1#state=0 DO ruletimer1 300 ENDON
ON rules#timer=1 DO Power1 0 ENDON
Result
ruletimer1 300 sets a 5 minute timer. After that time, fan will be switched off. If during the defined 5 minutes (or in general - when timer is counting) you the switch on, the timer will be canceled.
switchmode1 1 sets the switch in follow mode (LOW=off, HIGH=on)
If you have inverted switch (LOW=on, HIGH=off) then use switchmode1 2
