Reuse old smartphone on the side of my homelab to quickly glance at temps or access containers?

I have a couple of old smartphones and I was thinking of sticking one to the side of my homelab to check on temps, see running containers or even checking the containers from the smartphone. How would you do it? Is there a simple android app similar to homepage or glance that would allow me to do it? Also for power, is there a usb-c cable that I could connect to the motherboard of my server to power it? Like a 9-pin?
