ESP8266 NodeMCU + SHTC3 + PW1VA01 code help

Hello everyone Please help me in writing the code. There are two pieces of NodeMCU 8266. It is necessary to transfer humidity from one to the other. With the second one, the resulting humidity must be converted to 0… 10V. The SHTC3 sensor is connected to one, the PW1VA01 DAC Module PWM To 0-10V Frequency To Voltage Converter For Smart Home is connected to the second. Both nodemcus work in the Home Assistant. I will be grateful for any help.
