Used Rhino for years in my spare time, but my day job for 25 years was CATIA. The thing I always missed in Rhino is a tree that shows what is actually on each layer, so today I put one together.

It is a Python script for Rhino 8 (Windows tested). It shows:

the layer tree with an object count per layer
every object under its layer; click one to select and zoom to it, click a layer to select all of it
hide/show and isolate from the list
rename objects and layers in place

Add an alias (I use LO) and it is one keystroke away. Built by poking a stick at Ai until I got what I wanted..

Feedback and bug reports welcome. If anyone can test it on Mac, I would like to hear if it works.

Incase anyone is hitting the scenaro with the same issue, hopefully save someone my spin of frustration. 😄

Symptoms:

ENS160 boots successfully, firmware version reads correctly
I2C scan finds device at correct address
Stuck permanently in ENS160 readings unavailable - Normal Operation but readings not ready
Never produces eCO2, TVOC or AQI readings regardless of how long it runs

Hardware:

ESP32-C6 running ESPHome esp-idf framework
ENS160+AHT21 combo breakout board
Multiple I2C devices on same bus (AHT21 at 0x38, ADS1115 at 0x48, ENS160 at 0x52)

What didn't work:

Waiting 5+ days powered continuously
Adding 30s boot delay
Removing compensation block
Dropping I2C frequency to 10kHz (actually made it worse)

What fixed it: Increasing I2C frequency to 800kHz

yaml

i2c:
  sda: GPIO6
  scl: GPIO7
  scan: 
true
  frequency: 800khz

The ENS160 apparently needs a fast enough I2C clock to complete its internal initialisation handshake. At low frequencies it communicates but never exits warmup state.
