ESP8266 Community Forum

Hi!

I'm wondering if there is a way to change a variable remotely, like sending a value using the url of the NodeMCU/ESP8266 or something like that, or sending commands using command line or scripts etc?

I'm trying to create a wireless thermostat, and would like to be able to change the set temperature remotely.

Of course !
This can be done using URL with parameters send to Webserver sketch.
There are several examples posted in this forum.

Here an application including a webapplication to switch the variable remotely : http://iotests.blogspot.nl/2016/10/disco-on-demand.html
