Let's Control It

Hi all,
i am struggling with this issue.

My config:
ESP8266 Wemos D1
PCF8574
8 relay board
No devices configured and no rules configured.

When I startup the unit some relays gets activated.

Do I need pullup resistors with PCF8574?

Solved:
Using VCC=3.3V there was a problem during startup.

Using VCC=5V there was NO problem at all
