Web dashboard doesn't seem to work but mobile app does

I must be missing a step. Thought I followed the instructions but…
I started a project to just use a switch to turn off and on the onboard LED on an 8266. I created a template and set up the a data stream as VO and assigned a switch to it. I saved and applied. I have the Blynk library on my Arduino IDE and went to the blynk examples and selected the Blynk.Edgent_ESP8266 and created the sketch. I edited the sketch with my template ID and Name. For my first attempt all I wanted the 8266 to do was turn on the onboard LED and take a temp and humidity reading and do a Serial.print of the results. I compiled it and downloaded it to my device.

I then opened up my Blynk Mobile app and added the new device and set up a button and the VO datastream I set up on the was there and the set up was easy. I pushed the button an success. The LED went on an off as desired and at every push the temp and hum was printed on the serial out. Cool!

However the web dash was not getting the information. The switch didn’t turn off or on sync’d with the mobile app and also on the web dash I could click on the switch and the switch would animate on and off but it wasn’t getting to the device or the mobile app. Given that the mobile app had access to web produced datastream it seems things should have been connected. So I guess I’m missing a step.

While typing this the “topic similar” suggested " [Web dashboard switch on V0 datastream NOT WORKING" topic. I looked at that and saw that was fixed but changed my datastream to V3 and that worked with the mobile app but did not fix my problem with the web app.)

One other thing. A few weeks ago I was using the same device on a different WiFi network and everything worked both web and mobile and all was sync’d. To get the device freed up I uncommented #define USE_NODE_MCU_BOARD and recompile and downloaded and then held the flash button on the nodeMCU board and entered the new credentials and proceeded. I don’t know if that had any effect on the web dash but seems odd, to me, that it works with the mobile app which used the web defined datastream yet doesn’t work with the web dash. I must be missing something probably obvious. (Story of my life at 72+ lately.)

The web dashboard can be a little confusing.
There are two views - the design view - Developer Zone > Templates and the actual operational dashboard under Devices.

If you’re looking at the design view then it will show your switch, and you’ll be able to toggle it, but it will have no effect on your device.

Ensure that you’re looking at the device view web dashboard, as that’s the one you need to be using.

Pete.

Aw. Thanks, yes it is confusing because when I went there I didn’t see what I thought was the dashboard that I put together in the developer zone/web app page. I didn’t see a list that contained the dashboard that I thought I was designing in the developer’s zone as I thought it was already created but wasn’t showing up. So thanks for that. I’m not totally grokking it all yet but hopefully that will come.
