My Notes
--------
4 May 2023

In this workbook, I want to:
 - build a simple Xholon model based on the ideas and ojects in the NYTimes article
 - use hardware sensors to measure real light levels in the house or outside
  - use the generated data to decide what to do in the model
  - use simulated solar energy when light is available
  - use simulated pumped hydro when light levels are low or non-existent

I will use mqtt, node-red, grove sensors, picow/arduino/pizero
 - see my folders from late 2022 and early 2023, and my mqtt01 gist (14 Jan 2023)

Write down all the steps that I used at that time.
I was able to get the sensor data all the way to a running Xholon app.

Steps
=====

node-red (not required)
--------
cd
node-red

Welcome to Node-RED
....
Server now running at http://127.0.0.1:1880/
....
opened /tmp/sqlite ok
Connected to broker: mqtt://localhost:1883
 - Flow 5 is active
 - it is connected to mosquitto broker and sqlite which are both automatically available

Grove Beginner Kit
------------------
Arduino code:
  ~/Arduino/seeed/sketch_jan18d_KenzEnviro03/sketch_jan18d_KenzEnviro03.ino
  - with Arduino on Grove kit plugged into my HP ZBook USB port

minicom -b 115200 -o -D /dev/ttyUSB0
 - this works

OR (this works):
stty -F /dev/ttyUSB0 115200 raw -clocal -echo
mosquitto_pub -h 192.168.1.15 -t KenzEnviro/thl -l < /dev/ttyUSB0

Xholon workook mqtt01
---------------------
http://127.0.0.1:8081/Xholon.html?app=mqtt01&src=lstr&gui=clsc&jslib=mqttws31
http://127.0.0.1:8081/war/Xholon.html?app=mqtt01&src=lstr&gui=clsc&jslib=mqttws31.min
 - this sort-of works (but with an error that causes no data acquired)
 - ut see 5 May below :)

5 May 2023 - this works
-----------------------
- I haven't changed any code, but the following sequence of events now works

(1) plug the Grove Beginner Kit into the HP ZBook USB

(2) in terminal A  (base) ken@ken-HP-ZBook-15-G2:~$ 
    stty -F /dev/ttyUSB0 115200 raw -clocal -echo
    mosquitto_pub -h 192.168.1.15 -t KenzEnviro/thl -l < /dev/ttyUSB0

(3) in terminal B  (base) ken@ken-HP-ZBook-15-G2:~$ 
    mosquitto_sub -d -t KenzEnviro/thl
    - this visually confirms that I can get correct data

    Is It a Lake, or a Battery? A New Kind of Hydropower Is Spreading Fast.
    By Mira Rojanasakul and Max BearakMay 2, 2023
    
    These systems involve two reservoirs: one on top of a hill and another at the bottom.
    When electricity generated from nearby power plants exceeds demand,
    it’s used to pump water uphill, essentially filling the upper reservoir as a battery.
    Later, when electricity demand spikes,
    water is released to the lower reservoir through a turbine, generating power.
