The toilet is one of the most important rooms supporting a person in difficult and unusual situations, to which trouble-free access significantly improves the comfort of work. Unfortunately, for some time in Botland, we had to deal with the problem of toilets being always occupied, while the number of toilets remained unchanged, which caused growing frustration with every subsequent attempt to get to the desired place and time wasted to break away from work only to bounce several times through closed doors. The number of available toilets was out of our control, so the question came up: how to improve the traffic on the frequently used desk-toilet communication line<\/i>?<\/p>

For a long time the topic was hanging without an idea for its solution and here the idea appeared, we have no influence on when the toilet is closed, but we can easily present when it is open.<\/p>

The whole system is made up of two types of devices<\/b>. The main one, which is placed above the toilet door, and wireless indicators placed in most of the rooms in the company. The heart of the whole project is Raspberry Pi, on which Home Assistant is placed, with which all devices are connected via WiFi network. Modules built on ESP32 connect to the network and, thanks to an add-on for HA called ESPHome, have been integrated into the whole system.<\/p>
