Wall Cooler Automation with Power Saving Feature

​This code requires: - indoor gas sensor. - as many wall coolers as you want. - one station battery. When the temperature goes above 25C, the wall coolers will turn on, and if it goes below 15C, they will turn off. Before the wall coolers are allowed to turn on, the code also checks the current charge on the battery, and if it is below 1MW, the wall coolers will not be allowed to turn on (and turn off if they are already on) to conserve power. All these values can be adjusted to personal preference in the code. The max temp can be set in line 8 (default 298. 15K (25C)). The min temp can be set in line 9 (default 288. 15K (15C)). The battery charge threshold can be set in line 14 (default 1000000 (1MW)).
