I just finished a prototype of a analog notification solution built with Esphome and HA.
It consists of a NodeMCU with 4 LED’s which can be controlled from HA. The case and the icons are 3D printed. The icons are easily exchangable in case I want to monitor something else in the future, putting out the garbage or to see if mail has arrived.
Right now I monitor if i left the heater on patio (electricity), the water sensor registred water (drop), if the front door is closed and locked (key) and if the garagedoor is closed.
Of course everything can be checked on the phone, automated, nofified etc but nothing beats a quick peak to see that everything is in order.
Thought I’d share, perhaps anyone gets other ideas from this.
