XBEE3 constant disconnects on HA via ZHA

I’m trying to create an end device but this current setup has no micropython code yet. Upon connecting it to Home Assistant via ZHA it exposes all the GPIOS automatically.

One of xbee3-24 acts as a coordinator and 3 xbee3-24 acts as router nodes. I get constant disconnects every 2 hours. My first assumption is there is a sleep setting but on the XCTU setting it is set to no sleep. What might be causing this?


This is solved. Configured periodic sampling (IR ) on XCTU so it acts as keep alive signal to ZHA.
