Hi, im almost done with these.
But today I added SHT30 to my wemos and I have nov 2 json files, how can I have just one, with temp and humity?
Thanks

What do you mean with 2 json ? When you call the API ?
Send me the json you have

HI, system creates 2 sensor ID, so I just pull data from on on my wemos
one is 70977 for PM2,5 and 10, ad 70978 for SHT30.

OK I understand. I have never tried to put 2 TRHP sensors. Actually you can t change this. You have to merge in your code or show just 1

I have just seen you run the loop once every minute. The data are updated every 5 minutes. Please increase to avoid API overload. Will you put the code in a GitHub ?

I pull data once, than I use for loop to run it 10x in loop.
I can incrasse that to 20x times.
Or 4min is OK.

Yes I will, is very “dirty” need some polishing.

@divfili SHT30 should be added now.
