Hi all
I'm hoping someone can lend me a hand or point me in the right direction for the following issue.
I bought one of the preloaded SD cards on a new Pi B+ with the emonTX v3 all setup for 433Hz. Managed to get it all up and running on the preloaded builds, and sending data to emoncms. I haven't tried downloading latest SD card or emonTx images.
Problem now is that the feeds are only irregularly receiving data.
Below is an extract of the /var/log/emonhub/emonhub.log file after setting the config file to debug

This datasend then gets repeated at irregular intervals, ranging from ~5min out to 12 hours. Possible to see above that there was a major delay from 12:51 down to 16:09.
Any ideas or suggestions on how to diagnose ? Radio interference? I did initially have the Pi on WiFi, but is currently hard wired back to the router.
Thanks heaps in advance

Re: Irregular updating of emonhub
Hi Leigh
The log suggests rfm2pi isn't receiving usable packets as in debug mode emonhub will log every valid packet.
Can you confirm the frequency that the led on the rfm2pi flashes? if that led is only flashing sporadically it's not receiving packets and you should check the emonTx v3's range by seeing if moving them closer together improves things.

Re: Irregular updating of emonhub
Thanks for the reply Paul.
LED on the rfm2pi is irregular to non existent. I didn't realise that this is supposed this was supposed to flash each time. Current range is ~10-15m with a single brick and a few cavity walls in between, but I'll have a go at moving it closer.
I've since found a couple of posts by you and others about also using the serial connection into the emonTx. I assume that this would be the next step?
cheers

Re: Irregular updating of emonhub
You should only need to resort to a direct serial connection if the range/signal is being reduced by RF interference. if its just a range issue maybe using wifi so the Pi can move alittle closer is easier.

Re: Irregular updating of emonhub
I've moved the Pi closer & is now all good.
Thanks heaps for sorting out such a rookie error!
