Hi,
When the emonPi boots up the LCD should show the firmware version and detected sensors. In my case the LCD screen displays, in turn:
e2.10, then A DN and lastly D0 D. After this it will display the network IP and all OK. This started after I updated a new emonPi received 3 days ago. (updated via emoncms). I'm very new to the emonPi so any help on where to start looking will be appreciated.
Cheers.
Re: emonPi LCD startup display all wrong
+1 for me. My emonPi is doing the same. This started after I did the Jan 27th update <http://openenergymonitor.org/emon/node/11799>.
emonSD-22Dec2015.img and Emoncms Version low-write 9.3 | 2016.01.26
Re: emonPi LCD startup display all wrong
Still no bootup messages on LCD....
var/log/emonPiLCD file shows:

Re: emonPi LCD startup display all wrong
Hi guys, just seen this thread. Very sorry if an update has caused an issue. I will investigate this today and report back..
The log suggests that the emonPi LCD service cannot connect to redis. Could you confirm redis is running with:
$ redis-cli ping
the response should be: PONG
Also try:
$ sudo service redis-server status
Re: emonPi LCD startup display all wrong
Please run an emonPi update and let me know if problem still persists
http://openenergymonitor.org/emon/modules/emonpi#update
Please paste or attach update logfile to this thread.
Re: emonPi LCD startup display all wrong
Hi Glyn,
That solved it thank you very much! I now see all bootup messages. Attached logfile anyway if needed.
Another issue that has always been present is the WIFI signal strength on the LCD indicates 0%. On emoncms it says Link Quality: 55/70.
Cheers.
Re: emonPi LCD startup display all wrong
Oh dear, could you tell me what the output is when you run this in a SSH shell window:
$ ip addr show wlan0 | grep inet | awk '{print $2}' | cut -d/ -f1 | head -n1
Are you using the standard Edimax wifi adapter?
Re: emonPi LCD startup display all wrong
HI,
That command outputs the emonpi's IP address only.
Output of ifconfig wlan0 is:
wlan0 Link encap:Ethernet HWaddr c4:12:f5:07:d1:9c
inet addr:192.168.1.47 Bcast:192.168.1.255 Mask:255.255.255.0

Thank You.
