I have a problem with writing or displaying a DHT22 temperature and humidity value. If i connect temperature value (from Hygronometer node) to text node alone it works, if i want to connect both it does not.
Thanks for help
I don’t have a DHT22, so I haven’t been able to replicate your problem. However, I can display both temperature and RH outputs from a DHT11 on an OLED:
I noticed that on your dht2x-hygrometer node, the RH output is on the left and the Tc output is on the right. In the latest version of XOD (0.38.0), the outputs of the dht2x-hygrometer node are the other way around. Which version of XOD are your running? I wonder if an upgrade to the latest version might fix your problem?
Have you checked that you get both RH and temperature readings from your sensor? You could test your sensor using a patch with only the dht2x-hygrometer node and a couple of watch nodes:
I have a 0.38.0 version, i tried to do it with watch nodes. For split second it shows the value, the onther split is error blink.
I’ve no experience of using the DHT22, but I wonder if it is being sampled too frequently? Maybe try reducing the sample rate to 0.5 Hz:
