- Sun Feb 08, 2015 7:41 am #9239 The first thing I see is your argument transmission.

Thats what the array is for:
Instead of

Code: Select all"/update?key='..WRITEKEY..'&field1='..humi..'&field2='..temp..",{foo = "bar"},

better do:

Code: Select all 
  http.get('184.106.153.149', 80, "update",{key = WRITEKEY, field1 = humi, field2 = temp}, function (payload)


Also: Connecting to the wifi with tmr.delay(1000000) is not a good idea. My init.lua looks like this: https://gist.github.com/Manawyrm/ead702a90667593f7f76

The issue also could've something to do with the response from your server. I only tested that with Apache2.4. Could be doing strange things with other hardware.

This delay is not for connecting. I had problems with that application started before completing the startup Lua. So I tried this delay. Thanks for the answer.
