Pi loses RF conectivity

Falstone · 2016-11-18T17:32:51.252Z

I purchased a emonPi earlier this year. I connect to it a emontxshield to measure a 2nd solar array and a emontx2 to measure stored water temperature.
Recently it has started loosing connection to these modules. A quick reset of the Pi restores the connection but will quickly loose it again. I tried powering down the Pi for a couple of hours and the connection lasted 2+ days. Sampling from the on-board CT1 and CT2 continue unaffected.
Hardware or software fault? What is going on?

How recently? Have you recently updated the emonPi?

I have a few EmonTx units installed in various cities which keep going offline/ inactive. Why would this be and how can it be resolved? Currently they need to be manually reset at site which is not resource efficient.

Emon TXs not updating after Emonpi update

Emon TXs not updating after Emonpi update emonPi

This is a similar issue to that posted by @amaad but the details are a little different hence the new topic: Here is the old topic: I have been using an entirely shop bought oem system (with no modifications other than a firmware/software update in Sept) since June with one Emonpi and two TXs. I am strictly a user with no programming skills as yet. A few teething problems aside (all resolved by me so not likely to have been any fault of the equipment) the set-up has been running fine but t…

No I haven’t updated anything. I should have said that it is running the standard 3rd May image

Can you provide emonhub.logs when it goes down again next? rebooting the emonpi will over write the logs as they are held in RAM so you should fetch them before rebooting.

Where are you noticing/confirming the loss of connection? I assume your dashboards are not updating, does the inputs page show the same "last updated " time for both units when they fail or do they go down at different times?

Have you looked at the emoncms or emonhub logs during a fault condition to confirm the connection is lost?

Your are correct, the dashboard does not update. Looking at the feeds both
appear to stall at the same time.
How do I get the logs out?

Forgive me here if I misguide, you but I don’t use an emonSD/emonPi myself, but as I understand it, only the latest update allows you to download the logs via the web page so you can either cut and paste from the “config” page of emoncms or ssh into the emonPi and view/download the logs from /var/log/emonhub/emonhub.log.

if you need pointers on ssh and finding the logs, I believe there is info in “the guide” eg SSH, lets us know if you need assistance with navigating the logs.

EDIT - I have just upgraded your user status to allow you to attach the log files, you will need to save them with a “.txt” extension as “.log” files are not permitted.

Sorry, this issue could have been caused by a recent firmware update. Please run emonpi update in local Emoncms (Setup > Admin > emonpiupdate) to pull in the fixed firmware (V2.8).

Emon TXs not updating after Emonpi update emonPi

Quick version: Replacement emonTx units should not be required. I have identified an issue with the emonPi update (V2.7), I have pushed a new update (V2.8) which should fix the issue. Run emonPi update to pull in and apply the latest firmware (V2.8). Very sorry for the hassle. Please let me know how you get on. The long version: Well remembered. I am aware of the issue with V2.6, therefore V2.7 is based on V2.5, V2.7 has the same ‘RF keep alive’ as V2.5. HOWEVER, V2.7 was compiled with…

I updated the emonPi firmware ( now 2.8.1) and the fix appears to have solved the problems. It’s been up and running now for almost 4 days. No glitchs encounterd.
Well done.
