Peter - at the time you bought your emonTx’s the version was < v2.1 which is where a fix was implemented for a known “bit-slip” issue due to a long run of zero’s when the temperature sensor circuits were not used.
How many temp sensors do you have attached to the emonTx?
emonPi firmware has been temporarily rolled back to V2.5. While we investigate what’s going on. If a user now runs an update V2.5 will be flashed.
No “nodes” module preinstalled in this version?
I’ve installed this release
pi@emonpi:/boot $ ls emonSD-03May16
emonSD-03May16
As a result “node” menu is not existing.
I installed node module manually using git clone. Nodes appeared in the menu but “control feature” seems to not work.
If I issue a POST /nodes/nodeid /nodes/29/tx/values = 1,2,3,4, i get:

Found emonPi Update error for emoncms (git pull /var/www/emoncms) | Archived Forum but had no luck with any of the mentioned solution.
I use emonbase (raspberry pi running this this release ) equiped with rfm12pi v2 (RFM12Pi V2 - OpenEnergyMonitor Wiki)
Any clue?
Note: after i installed nodes i can see the Inputs and nodes updated. Just I cannot use “control features”
Should I use another image? Do i need to configure something because i don’t use emonpi but emonbase?

Nodes module has been replaced by mqtt input
Any data published to /emon base mqtt topic will appear in emoncms inputs
Hi Glyn -
When you say the nodes module has been replaced by mqtt, how difficult will it be for those of us (like me) that have never used mqtt and already have our emonpi setup with all of our nodes and pushing to a remote emoncms (v9.4) server?
Is there some kind of walk-through we can see (examples, etc) before we commit to upgrading?
I am just concerned that I will upgrade, things will break, and I will have to learn (on-the-fly) mqtt to try and get everything back up and running. 
Thanks
Should be explained here, let me know if you have any questions or any part could be better explained.
MQTT - Guide | OpenEnergyMonitor
You shouldn’t need to touch mqtt if you don’t want to. When using the new image, anything emonhub receives will just appear in the inputs section. See the local logging section of the new guide. Using mqtt like this instead of the nodes module makes it much easier to connect other integrations such as nodeRed etc to add functionality, since its possible to subscribe to a particular node / key via mqtt.
Thanks Glyn -
I read through the mqtt, but I guess I am still a bit confused. Is there still an emonhub.conf where we control what makes it into our inputs (formatting, etc)? I do not log anything locally but instead have my own emoncms server, will anything change in the way this data gets to my server with the new version?
Thanks!
I doubt this is confined to this release, however…
I thought I’d have 3 bargraphs for a 3-phase supply, using the phase colours.
Err… Ahem… I think there’s a slight issue of readability!
[Apologies if I’ve got a cynical brain 
]
Maybe it is like that when the reading is so high that you wouldn’t want to see it ;o)
Don’t believe the numbers - I was using my CT test rig. So only about 30 real watts being dissipated. 
I’ve made a fresh install with the emonSD-03May16 image, and ran the update via the admin. All is up and running (thanks for the great work!), except for one oddity: MQTT login fails on port 1883. When I try to reach the MQTT server, Chrome replies “This site can’t be reached”.
Nor sure if it is related, in admin the logger (/var/log/emoncms.log) diplays a warning:
2016-05-18 09:52:39.999|WARN|phpmqtt_input.php|Starting MQTT Input script
2016-05-18 09:52:41.681|WARN|phpmqtt_input.php|Subscribing to: emon/#

And Server Information (in admin) states
MQTT Version n/a
localhost:1883 (127.0.0.1) - what is that IP address (I connect to emonpi at http://192.168.0.132/)
Any idea what is playing up?
thanks,
Marc
How are you trying to connect? Try mqttlens Chrome extension.
Are you referring to the connection error in the logfile? The connection error was then superceded by a successful connection message, it’s just that MQTT server takes a while to fully boot up at startup. Good to hear image is working for you.
Have been trying to connect through browser screen, same way as NodeREd and OpenHab (assumed it would work similarly) allow. Now mqttlens did the trick. Maybe good to mention this in the changelog with the SD release. Anyway, got connected, thanks!

Ah yes, this is MQTT not HTTP. This is why your browser would not work
New image has been launched, see blog post
The new image is now shipping by default pre installed on all emonpi and emonBase, together with a RaspberryPi 
Thanks lot for helping with all the never-ending testing and debugging. This is quite a milestone, since up until last week we were still shipping the last stable image from June of last year with emoncms 8!
Hi, congratulations for your work!!!
I have a problem, i want send the information to private server by 3G. All work well, but the data traffic is very high.
i put the “sendinterval = 300” and “batchsize = 200” to mi server the ip conections is every 5 minutes.
But i put iptraf program and i can view that emonbase send information to 80.243.190.58:443 and recive traffic of 85.62.229.133:53
any idea to eliminate this traffic???
Thanks for all!!!
Is the emoncms.org SSL port so if you do not want to send data to emoncms.org just remove the emoncmsorg interfacer from emonhub.conf or disable it by commenting out the interfacer type eg
[[emoncmsorg]]
#Type = EmonHubEmoncmsHTTPInterfacer
[[[init_settings]]]
[[[runtimesettings]]]
pubchannels = ToRFM12,
subchannels = ToEmonCMS,
url = https://emoncms.org
apikey = xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
senddata = 1 # Enable sending data to Emoncms.org
sendstatus = 1 # Enable sending WAN IP to Emoncms.org MyIP > https://emoncms.org/myip/list
sendinterval= 30 # Bulk send interval to Emoncms.org in seconds
The # before “Type” will prevent this interfacer being created.
The traffic on 85.62.229.133:53 is Orange (Spain) ISP’s DNS lookup so (assuming that’s your ISP) you probably need that unless perhaps you are sending to a domain (your private emoncms server) that has a fixed IP address in which case you could try replacing the domain name in the url with the IP address in emonhub.conf to reduce the need to look it up.
