Access point for ubiquiti is not showing accurate data in home assistant

i got ubiquiti unifi controller working with my home-assistant and it is pulling rssi data, however, the information that show’s in home-assistant is about 4-5 dBm’s off, unifi shows my iphone constantly at -53 while, home-assistant fluctuates between 39-44, shouldn’t they be identitical since home-ass is pulling from the server? i have been monitoring this for the past few minutes (with detection time being 30 seconds). also the phone hasn’t been moving around
