Get PriceUse low level triggered relay. OR Some of the NodeMCU pins momentarily turns 'HIGH' (3.3V) when switched on or restarted which causes the relay to change its states. I've read that D1 (GPIO5) and D2(GPIO4) pins of NodeMCU don't change their states on restart. So you can try using these pins for controlling your relay board if you don't wish to buy a low level triggered relay module.
