Homey Pro 2019 in sleep mode?

My Homey Pro 2019 has been doing okay for the most part, but I’ve noticed it seems to go into some kind of sleep mode more often now.

  1. My motion sensors (Fibaro) often trigger flows with a delay of more than 5 seconds.
  2. When I give commands via Google speakers, it almost never works on the first try, but usually on the second or third.
  3. When I open the app on my iPhone, I often don’t have a connection unless I’ve had the app active recently. Then, I will just see a screen with the app trying to reconnect, and it usually succeeds after 2-3 attempts. Can I fix this somehow? And do you think it would work without issues id I buy a 2023?
