Re: Possible to manually rollback to previous firmware using SD card only

I'm going to guess at "sudo rpi-update". Something that most people should never use. Correct The second stage bootloader "bootcode.bin" and its associated files on the SD card are frequently referred to as "firmware", as they are not part of the OS and are similar in function to what would be the ...

Possible to manually rollback to previous firmware using SD card only

I made the mistake of installing the latest firmware on one of my RPi3B+ units. Now it will not boot up. Is there a way using only the SD card and a SD card reader to roll back the firmware?

Thanks

Re: TEMPer USB sensor - How to use

may i suggest you look at mqtt messaging and install the mosquitto mqtt broker onto your pi. you can then use the python mqtt lib as detailed in this beginners guide to very simply publish the temperature reading as a Mqtt 'Topic/payload' message. http://www.steves-internet-guide.com/into-mqtt-pyth...

Re: TEMPer USB sensor - How to use

All of those things should be doable just by expanding the Python script you made to read the value. How easy it will be, depends on your Python ( or basic programming ) knowledge. For example, to log to a file is basically learning: - find local time/date - open a file for writing. - write date/ti...

Re: TEMPer USB sensor - How to use

Its good if you could tell us: - Where should the log be stored ? - How/Where should the alert be sent ? - Where should any graphs be visible ? Meanwhile here is a simple pointer: http://dweet.io Example output of a sensor broadcasting on dweet.io : https://dweet.io/follow/jexplotacion Ah, I should...

TEMPer USB sensor - How to use

I purchased a TEMPer USB temperature sensor to use with a Pi. It was advertised as 'works with Linux' ... which I guess is sort of true, but not the way I was imagining. So far I have followed this link from ModMyPi and I can get a readout. I was hoping I could log temperature, maybe even send alert...

Re: How to mount external SSD

Since it looks like you have figured out your issue i'll make a quick suggestion. Use "LABEL" to mount you drives in fstab. This webpage will help you along. http://man7.org/linux/man-pages/man5/fstab.5.html The reason I suggest using "LABEL" is that if you ever need to replace a drive for whatever...

I don't think this is possible. When you shut down your Raspberry Pi, you are basically stopping all processes.
What about some sort of Wake-on-Lan (or similiar) method. Not sure if that is supported by the PoE hat.

Auto turn on

Is there a way to configure a Pi to turn on so long as it has power, even if it is shutdown by command (either the GUI or the command line). I am installing a Pi in a remote location, my biggest concern is it shutting down and not being able to be restarted. The Pi in question is powered via PoE, if...

You might want to add nofail to the options, so that if the drive is not connected your system will still boot. Other than that it looks okay.
Thanks!
