What is shown in the Domoticz log? Do you see there that it has updated the sensor values?

Ok, the sensor gets updated as you can see the ‘last updated’ timestamp.

We now need to now how we provide the correct values to the sensor based on its type.

Try this on the command line

Code: Select all

curl -s -i -H "Accept: application/json" "http://$SERVER/json.htm?type=command&param=udevice&idx=10&nvalue=0&svalue=“11;77”

As see what it does.

Play around with the values between the quotes of svalue.

Press CTRL+c to abort

Remove the “ before http and try again

Replace $SERVER with 127.0.0.1:8080

Replace both the “ at the end with ‘

The command should be

Code: Select all

curl -s -i -H "Accept: application/json" ‘http://127.0.0.1:8080/json.htm?type=command&param=udevice&idx=10&nvalue=0&svalue=“11;77”’

If it return 401 Unauthorized, there is a permission issue to solve first.

Hopefully this works

Ok, we are fighting with the command line interpreter here. I will try it myself and get back to you later...

Maybe you can google in the mean time to figure out how a correct command should look like. I think there should be plenty examples on this forum.

[arhangel76]

i find new script:

https://prnt.sc/v583et
and contain this text:

import Adafruit_DHT
import time

DHT_SENSOR = Adafruit_DHT.DHT11
DHT_PIN = 4

while True:
humidity, temperature = Adafruit_DHT.read(DHT_SENSOR, DHT_PIN)
if humidity is not None and temperature is not None:
print("Temp={0:0.1f}C Humidity={1:0.1f}%".format(temperature, humidity))
else:
print("Sensor failure. Check wiring.");
time.sleep(3);

@arhangel76

Please try the command below. Make sure you have the double-quotes around both parts

Code: Select all

curl -s -i -H "Accept: application/json" "http://127.0.0.1:8080/json.htm?type=command&param=udevice&idx=10&nvalue=0&svalue=10.3;66;0"

Can you show the output?

And to update the values: You see svalue=10.3;66;0 where the first (10.3) is the temperature and the second (66) the humidity. The third (0) is not used here.

So you have to modify your script to this

Code: Select all

curl -s -i -H "Accept: application/json" "http://$SERVER/json.htm?type=command&param=udevice&idx=$DHTIDX&nvalue=0&svalue=$TEMP;$HUM;0"
