No probs with sending MQTT from signalk node-red app - just 2 nodes needed, very doubtful you could even measure the increase in processor resources even with many sigK data getting sent. Then if it's just a simple 4 x 20 an ESP can do it without programming using espeasy. A button to scroll though different pages might be handy. I've had one like that running as a test & hopefully will make something more permanent with a 18650 battery/charger so it can run with or without power. Would be very useful sailing solo.
Slight aside, but the esp32 has capacitive touch sensors built in, I've just got an esp controlling the volume of a plugin hifiberry amp over mqtt by touching pins. Could be a handy way to communicate with fewer holes in the box.
