ESP8266 with ultrasonic sensor interfere

I have some hc sr04 sensors (ultrasound sensor) installed on 4 chairs (see photo of red chairs) and each connected to an Esp8266. When a person sits on a chair the sensor detects it because the distance is less than thirty cm and a command is sent via wifi to a raspberry PI on which some videos must be started. I already have some scripts for Arduino (for each Esp8266) and a python file for the raspberry but unfortunately they don't work as it should. The problem is that the 4 sensors being in the same room interfere with each other and often give wrong readings, thus obtaining that the films start even if a person is not sitting. I need some good ideas to solve this problem. One could be to make the four sensors work cyclically so that at the same time only one is in operation in order to receive only its echo. The Esp8266 are connected in a local network not internet. For me it is very urgent and I need to resolve the problem within 12 hours from now. Thanks to those who can help me.

Hello I can't bid on your project But maybe this can help a little 1-When there is no one sitting on any of the chairs , your sensors should read 0 or readings discarded -This must be adjusted ofc according to Plus
