Time

[superjasiek]

Hi! First of all thank you very much for this grate piece of software. Everything goes smooth with dock installer and volumio installer (I use raspberry pi zero w with hifiberry dac + and lcd hd44780 i2c, on adress 3F) . Setting accuweather was a little tricky about location code but it works fine. There is one thing i can't figure out - how to change clock format - I set time zone to Europe/Warsaw and set true to 24h clock but lcd still display 12h clock. One more time thank's for your time for developing this soft!

I found also sth like this - log file

Not sure what would cause that exception except possibly a bad pages file. Which one are you using? As for the 12 vs 24 hour issue. The 24h setting is no longer enforced. That has moved into the pages file. If you look in the file you are using examine the definition for 'time' in the set of widgets. You'll notice the variables list has a single value which is 'localtime|strftime+%-I:%M'. Just change this to 'localtime|strftime+%-H:%M' and you'll get a 24 hour clock.

Thank's for reply - made changes and everything works fine. I think that this exception was made by my code in python for rotary encoders (two scripts for two encoders run by system service) - is it possible? Maybe you have some hints to improve it? I use page file 16x2

'#!/usr/bin/env python import sys import time import os from rotary_class import RotaryEncoder

PIN_A = 13 # Pin 16 PIN_B = 26 # Pin 18 BUTTON = 24 # Pin 22

This is the event callback routine to handle events

def switch_event(event): if event == RotaryEncoder.CLOCKWISE: os.system ('volumio volume minus') time.sleep(.2) elif event == RotaryEncoder.ANTICLOCKWISE: os.system ('volumio volume plus') time.sleep(.2) elif event == RotaryEncoder.BUTTONDOWN: os.system ('volumio volume mute')

elif event == RotaryEncoder.BUTTONUP:

         # os.system ('volumio volume unmute') 
    return

Define the switch

rswitch = RotaryEncoder(PIN_A,PIN_B,BUTTON,switch_event)

while True: time.sleep(0.5)' and rotary class looks like this: `#!/usr/bin/env python

` And last question: is it possible to change weather info provider? for example for openweathermaps or sth? Where is code that is responsible for this part (weather)?

I don't see how your encoder program would have affected the exception in you experienced in pydPiper. The encoder program itself is a bit hard to follow without some additional details. For instance, it appears you have your callback function is defined twice. It also appears that you are using sleep to debounce the inputs. You may want to look at using the bouncetime feature of add_event_callback instead.

GPIO.add_event_callback(channel, my_callback, bouncetime=200)

For your weather question: The currently supported weather services are Weather Underground and Accuweather. I added Accuweather after Weather Underground discontinued issuing free API keys. I used to support open weather map as well and adding it back would not be difficult. I pulled it though because it was providing inaccurate data. It is possible that this is fixed at this point. Let me know and I'll look into re-integrating it.

Hi again :) Just updated pydPiper (using instruction on github) and have same issue - how to change time from 12h to 24h? is there any way to force 24h clock? I edited page file - 16x2 'localtime|strftime+%-H:%M' but it does not work. Also question about weather service is it possible to run accuweather like in previous version? Thanks!
