I am thinking of buying sonoff nspanel pro. I have wifi wall switches tx and I don’t care about the lighting. But I was thinking of using the nspanel pro with 4 sonoff zigbee thermostatic valves (trv’s) as a room thermostat. Also i want to use it as an alarm with 8 door and window sensors and 3 motion sensors.
How many devices can I put in? Is there any limitation?
I have also seen in videos that show that there are some screens (user interfaces), the main and some after. As in our smartphones.
Are these specific or can other screens be added as in our smartphones?
