Hi, I have began to undertake a project that allows for control over a pump and ventilation fans in a small greenhouse as well as being able to view data on temperature, humidity and soil moisture remotely. Using an ESP8266 I have set up a soft access point and a web server. The server should display the data wanted and allow for an on/off button for the pump and for the fan. Currently the site works in the way I want it to. It displays this data (Dummy numbers for now, planning to code in the sensors after) and when I click the on button for the pump or fan it updates the page and it becomes an off button. However, the output pins are not doing what I need them to. They are attached to relays so that when there is output the relay switches and allows the pump/fan to draw current. Currently, only pin 13 is giving an output and it is just constantly turning on and off regardless of what buttons I press on the website. Below is the code and I will link the device I am using. Please help me make this work in the way I would like it to.
