Hello,
Would it be possible for you to add your config.txt file here so that we can better understand your question?
We are unsure what you mean by converting to set values in decimal.
Hello Makenzie,
Thank you for your reply.
My confusion is with these values:
minimum_light_threshold=-5.920000076293945
maximum_light_threshold=18.15999984741211
minimum_temp_threshold=23.600000381469727
maximum_temp_threshold=30.399999618530273
minimum_humidity_threshold=55.20000076293945
maximum_humidity_threshold=66.79999923706055
By checking I can see it does 10 readings:
for i in range(10):
tsl = tsl2591.Tsl2591() # initialize light sensor
full, ir = tsl.get_full_luminosity() # read raw values (full spectrum and IR)
lux = tsl.calculate_lux(full, ir) # convert raw values to lux
humidity, temperature = Adafruit_DHT.read_retry(int(which_dht), int(which_data_pin))
light[i] = lux
temp[i] = temperature
humid[i] = humidity
for each array it gets the min/max
minLight = min(light)
maxLight = max(light)
minTemp = min(temp)
maxTemp = max(temp)
minHumid = min(humid)
maxHumid = max(humid)
there is some hard coded buffers in the script
unwarranted alerts
light_buffer = 10
temp_buffer = 3
humidity_buffer = 5
Then it generates the min/max thresholds by taking min(sensor)-threshold / max(sensor) + threshold
It looks like the values it took when generating the config is:
light : 5.9 - 8.1
temp = 26.6 - 27.4 celsius
humidity - 60.2 - 61.8 %
I just want to make sure that I am understanding the code correctly because if I set the wrong values I will never get the slack notifications.
Regards,
Lauren

Hi Lauren,
First of all, thank you for your interest in the GMPI. If I understand your question correctly, you are asking if “min(sensor)-threshold / max(sensor) + threshold” is how the buffer works and is applied to the min/max values for the alert thresholds? If so, yes, I believe that is correct. You could test this theory by inserting a print statement so that you could see all values stored in the array (noting min and max), and then by changing buffer values to see if they give you a predictable output based on the above mentioned formula. I would also recommend intentionally setting thresholds out of range of what the sensors are reading in your testing environment to intentionally throw error messages to your slack to test that this feature is working correctly, and then return thresholds to previously calculated values, or rerun program to generate new threshold values. Best of luck in your endeavors!
Regards,
Brandin Grindstaff

The buffer variable adds a buffer to max and min values to prevent

Please feel free to adjust these values.

Hello,
I am using the GMpi package, the config.txt file has been generated but I am stuck in the threshold configuration since I am not sure which conversion has to be done to set the values in decimal since for temperature, humidity and light, the units of measurement are different.
I appreciate any guidance that can be provided.
