hey blynkers, i get this message on my serial monitor when I start the Blynkedgent program.
the program works fine but keep getting this readout every 1 sec on my serial monitor. i did hold reset for 10 sec. but still happens…
Blynk edgent is waiting for you to provide your SSID and your password ? 
Connect with your phone you will see the home page.
Difficult to say unless you post your sketch, and provide details of the board you are using and what configuration you have in your Settings.h file.
Pete
It seems you are using the reset pin for something else in your project. The reset pin they are referring to is not the reset pin on the board. If I remember correctly D8 is used as the reset pin.
It seems like gpio0 is on D3 on the “D1 R2” boards.
ok I will try to post my sketch ? I have never done this ? how may I ask do you post your sketch ?
yes and I am using the wemos D1 mini and I am using gpio15 and 16 in my sketch , maybe this is not going to work…
You put triple backticks on a blank line above and below the code.
Triple backticks look like this:
```
Copy and paste them if necessary.
Pete.

GPIO0 is being used as the button that you press for 10 seconds to reset the provisioning data, so should have a physical push switch connected to it, but you’re also using it for your one wire bus.
It seems like you’ve run out of GPIOs. Maybe time to use an ESP32 instead?
Pete.

so I should leave D3 open and not used ?
As In said, D3 should have a push switch attached to it, but if you do that then you have nowhere to connect your Dallas temperature sensor.
Pete.
ok I see I might have to do some redesign , I just have a **** load of wemosD1 mini. maybe I will use the ESP32… thanks so much Pete , you da man… 
It depends on whether you want the Edgent functionality, and also whether you want everything connected to one board.
If you don’t want Edgent and Blynk.Air then use a simpler static provisioned sketch.
If you want to use multiple boards, maybe in different locations the use the HTTP(S) Bridge approach.
If you want everything then an ESP32 is the way forward.
Pete.
you are absolutely right, by me using gpio 0 as temp sensor input caused all the trouble. all is good now.
