<b>Warning</b>:  file_get_contents(/home/pi/data/emonhub.conf): failed to open stream: Permission denied in <b>/var/www/emoncms/Modules/config/config_controller.php</b> on line <b>32</b><br />

It might help somebody else if you say what you did to solve the problem.

Hi Thomas,

What was it that solved your static IP address issue?

Regards,

Bill

hi ; to solve it i downloaded the image from the website, extracted it to another sd, then with linux (as root) rewritten the ip-settings to my desired fixed address, and all functioned okay. i think there went something wrong with ejecting the usbstick with the microsd after rewriting the ip info the first time. still have problem i cannot get the realtime graph to show anything in visualisations or dashboard, the 'app' - my electric, and nodes do come with values showing. i'l update the post if i get those functioning

I had the same issue.

EmonHub Config Editor in the UI

<b>Warning</b>:  file_get_contents(/home/pi/data/emonhub.conf): failed to open stream: Permission denied in <b>/var/www/emoncms/Modules/config/config_controller.php</b> on line <b>32</b><br />

I fixed it by logging by ssh

then:

[email protected] ~/data $ ls -lh emonhub.conf 

-rw-r----- 1 pi pi 8.9K Jan  5 21:53 emonhub.conf

[email protected] ~/data $ rpi-rw

Filesystem is unlocked - Write access

type ' rpi-ro ' to lock

[email protected] ~/data $ chmod a+r emonhub.conf 

[email protected] ~/data $ rpi-ro

Filesystem is locked - Read Only access

type ' rpi-rw ' to unlock

[email protected] ~/data $ ls -lh emonhub.conf 

-rw-r--r-- 1 pi pi 8.9K Jan  5 21:53 emonhub.conf

Then the content of emonhub.conf in the web ui, was the same as the one in the file system. It seems the file got wrong permissions at some point.
