To power up, all that’s required is to connect physical pin 5 (BCM 3) to the ground next to it. This functionality is enabled by default.
To shut down with the same button, just add the line
dtoverlay=gpio-shutdownto /flash/config.txt
config.txtis read onlyto edit ssh
Codemount -o remount,rw /flashthen to make it read only again
Codemount -o remount,ro /flash
Millions of Thanks!!!
Yeah thats what I mean gpio3 and the gnd across it...you add dtoverlay=gpio-shutdown to config.txt..
If I want just to start rpi only do I need to add the dtoverlay=gpio-shutdown to config.txt. and 1 maybe stupid question - where is this config.txt file on pri4
That will be usefull just for startup if it works...basically reboot and shut down are the same as the ones you r using now from Kodi power menu..so you can set the remote buttons even without switch..
Just a quick idea is a transistor between pin 5 and 6 and an ir receiver connected to it...basically if you short pin 5 and 6 rpi will start.
True for the reboot and shutdown. In fact I am using the Kodi app on the phone as a remote control but for the activation I can not use it
So you said just shorting pin 5 and 6 will start rpi( you mean GPIO3 and GND)??? Directly shorting them with nothing else?
Your explanations are very useful. I was thinking to implement such a button on my Pi4 BUT I was thinking... What if the power button is with IR for the regular TV or Bluetooth from the phone. Is this possible to be done? I think this will be just a bit better for usage
Thanks again for your explanations!
You just edit script and restart to try with 50% to 100% but you dont really have to..if fan is working all should be fine
If you want to try change values just ssh systemctl reload fan.service or stop and then start service
checked
There is a difference in the speed definitely . Mine is starting from 30 as well
Thanks for the support!
This is clear I will try to change but how to stop the fans now. They are running based on the fan and service scripts
Thank you!
Post #74 I posted a small script calibrate.py
That is similar script to the one on #60 but works manually from terminal instead of reading temperatures...it's just for testing and to find your fan minimum speed...mine started at 30%...less then that and it wont turn...
You can test fan with that script from terminal....you type 50 will be 50% speed..100 will be 100% speed and so on...
How can I verify that the speed fan is temperature controlled? I am looking at it and speed seems the same all the time
Did you connect transistor base to the proper gpio?
yes,
all is fine now! I repeat the steps in #58, used the fan file from #60 and it starts
now trying visually to check the speed change of the fans
before with no fan temp was 53 deg Celsius now is stable 44-46
Thanks a lot for your guidelines and support
What are you planning to do?
2 pin 5v fan ?
Script in post #60 works fine for PWM temp/speed control..
You just need to make circuit..
2 pin 5v fan
I made a circuit with 2n2222 transistor and 1k resistor I use the following circuit
Temperature Controlled Fan for Raspberry Pi 4 - Fizzy
but I would like to use your script from #60 because of the speed control
I just change the fan file from the link above with your script from #60 and now intend to turn it on
Seems I made something wrong(either circuit, either places for the script, .. or something else) as I turn it on but the fans are not starting
I have a great request:
Can you sum up 1 working solutions with all the steps needed in your first post as the topic is interesting but it is going longer and longer.
The topic is growing and in 1 part we have scripts, update in another, after there is script with variable speed and for me it is a bit confusing
Thanks in advance!
I think my issue is a bit different
Hello,
seems I have the same issue
did you find a solution?
Yes,
This seems the best
Have to check if there is an m3u list from Stalker and send it to Tvheadend.
just was not sure due to the fact that on LIbreELEC I have Stalker client with account and password for it. I was wondering how to put them on Tvheadend as I did not see account and password association from Stalker to Tvheadend.
have to check if the client is generating an m3u list somewhere in try to add it in the Tvheadend
thanks for the idea
you can't share the client signal, you can only share the stalker server signal - the server is running at your stalker device
no idea actually how to use it and if it is possible - you may google how to connect stalker -> tvheadend
I found the same
But on Kodi as signal I have only Stalker Client
Is there an add on for Stalker server ?
How to install Stalker server on Kodi?
Stalker server -> Kodi stalker client -> Tvheadend server is not working
Stalker server -> Tvh Server -> whatever is maybe ish working (not sure what the Stalker server is able to do)
Then how I am able to share the Stalker client signal from 1 device to 2 different TV's? Is there such a way?
Do you mean
Stalker Server -> Tvheadend Server -> Kodi Tvheadend Client ?
in fact I think is Stalker client in Kodi where I have subscription. My idea was to use this subscription and send the signal Kodi Tvheadend Server -> Kodi Tvheadend Client and see it as well from my other TV in the internal network
Hello,
I have similar issue
I am running TVheadend server on the Android TV box without DVB. I load the server and my channels list, I see them there, I see the channels even in the TV under TVheadend HTSP Client. BUT when I try to open a channel I am getting the following message " No free adapter available"
I try to create an user in the server ad add user pass on the TVheadend Client but still having the same issue " No free adapter available"
Any kind of help to resolve the issue ?
