Is this what you meant to do above? It seams like it works.

I already have this entire setup running on the dash and all the sensors work and all the omegaexpansion modules as well. It just does not work when I run the micropython command.

Can this too be sym linked?

@tjoseph1

Thank you for your assistance. Certainly, the more I know the better I will understand how this all pulls together. What you've shared so far is helping quite a bit. I'm onto the next issue now.

root@Omega-C592:~/OmegaHomeControl# micropython dash.py

So now its how to add the relayExp as well. I'm working through what you shared but in the context of the relayExp. I haven't figured this one out yet.

Any ideas here?

echo $PYTHONPATH

This just creates a new blank line. Nothing is returned.

"opkg list-installed

This does list the installed packages. The issue I now have is that when I run "micropython script.name.py" command with the file, I get an error "ImportError: no module named 'OmegaExpansion'"

The same file works with the non-dash omega, AND the dash when I run "python script.name.py".

As far as I know, I have to use micropython to run the GUI library.

This is installed:
lv_micropython - 1.9.2-2
micropython-lib - 1.9-f5fe55aaef1a39d3d56f07040c0ff9f7e841fdf7-1

pyOmegaExpansion - 0.9-1
python3-omega-expansion - 0.9-1

@tjoseph1

I have both of those installed, however it still throws the OmegaExpansion error is missing.

root@Omega-C592:~/OmegaHomeControl# opkg list | grep -i micropython
lv_micropython - 1.9.2-2
micropython-lib - 1.9-f5fe55aaef1a39d3d56f07040c0ff9f7e841fdf7-1

@tjoseph1

Although Micropython is preferred, it doesn't work for the dash I have. The micropython command for some reason lacks access to the same libraries that python has.

Again, I can run python mypython.py file
where I cannot run the same file with micropython mypython.py file.

"
The next part of this is getting the call micropython swtich.py to be what activates the swtich file instead of calling python switch.py

This is so that I can use the Micropython & LVGL support of the Dash. link

but when I call micropython switch.py it dumps this error: ImportError: no module named 'OmegaExpansion'

Just out of curiosity, I changed the switch on the adc to 0x49 and I changed the code for the motion sensor to 0x49 and the sensor now triggers the relay! So perhaps there is something about 0x48 and 0x49 on the dash software?

Again, the 0x48 switch and code work on omega2+ but not on dash.
On the dash, the 0x49 works. Here is the motion sensor code for reference.

from OmegaExpansion import AdcExp
import time
import threading

class Motion:

  def __init__(self, station=None, threshold=None, parent=None):
    print('********** Motion Module Starting **********', station, threshold);

    if station is None:
      raise ValueError("An Address must be passed into the constructor argument 1.");

    if threshold is None:
      raise ValueError("A Threshold must be passed into the constructor argument 2.");

    if parent is None:
      raise ValueError("A Parent self must be passed into the constructor argument 3."

    self.station = station;
    self.threshold = threshold;
    self.adc = AdcExp.AdcExp(address=0x49);
    self.parent = parent;
    motionThread = threading.Thread(target=self.listen);
    motionThread.daemon = True;
    motionThread.start();

    self.listen();

  def listen(self):
    while 1:
      print('station: ', self.station, self.threshold);
      print(self.adc.read_voltage(0));

      if self.adc.read_voltage(self.station) > self.threshold:
        self.parent.motionOn();
      else:
        self.parent.motionOff();

      time.sleep(1);

and here is the parent switch.py file that calls it.

import time

from relays import Relays
from motion import Motion
from light import Light
from temp import Temp

class Switch:

  def __init__(self):

    self.motionDetected = False;
    self.relay = Relays(7);
    self.relay.setAllOff();
    self.motion = Motion(0, 3, self);
    # self.light = Light(3, 1000, self);
    # self.temp = Temp(1, 85, self);

    self.start = time.time();

    while True:
      print('||||| SWITCH ACTIVE |||||');
      time.sleep(10);

    self.status = 0;

  def motionOn(self):
    self.motionDetected = True;
    self.relay.set(0, 1);

  def motionOff(self):
    self.motionDetected = False;
    self.relay.set(0, 0);

  def tempOn(self):
    self.relay.set(1, 1);

  def tempOff(self):
    self.relay.set(1, 0);

  def testOn(self):
    print('testOn');
    self.status = 1 - self.relay.read(0);
    self.relay.set(0, self.status);

  def lightOn(self):
    if self.motionDetected and self.relay.read(0) == 0:
      self.relay.set(0, 1);

  def lightOff(self):
    if not self.motionDetected and self.relay.read(0) == 1:
      self.relay.set(0, 0);

Switch()

It would be nice to know the diff. I have 4 Dash, so I can try this on the others as well, but it will take time before I can get to them.

For now, I'll focus on just getting one to work.

The next part of this is getting the call micropython swtich.py to be what activates the swtich file instead of calling python switch.py

This is so that I can use the Micropython & LVGL support of the Dash. link

Unless I can use it with just python?
