Toilet Paper Roll Counter Box
As I was sitting on the toilet the other day, I discovered we had no toilet paper left. Luckily I survived the event, but figured that this could never happen again!
Therefore I made a box that counts the number of toilet paper rolls, which also warns me if we're running low. Everything done with the help from Home Assistant and ESPHome 🎉🤩
If we have less than 4 rolls, we get a subtle warning from the box
And if we have less than 2(!) rolls left, the box goes into EMERGENCY mode🚨🚨🚨
Built this using:
- NodeMCU V3
- HX711 and a load cell
- Gilde Box (any see through plate would suffice)
- Clas Ohlson Wooden Box
- 12V PSU
- Barrel Socket
- WS2812 LED Strip
The new box:
Cutting of Gilde for the plate inside the box:
Checked that the plate fits in the box:
The hole for the barrel plug:
Didn't have a drill that fit the barrel plug, so decided to make a bigger hole, and then 3D-print an adapter for the plug:
Mounted the load cell to the plate, and another plate as the bottom:
Placement of the LED Strip:
The code is made in ESPHome, a super easy way to make code for sensor and other stuff for Home assistant.
Here it is!
