Hi Robert, thanks for your information, I had forgot that I had updated the sketch, and that it does not flash the red LED any longer. I took the emonTX V3 to bits, and had a close look at it, nothing obviously wrong with it from what I could see visually,
After my email post I locked back at my original notes from when I originally installed the system, and found that what I was seeing on the “Programmer - USB to serial UART” was exactly how it worked after I installed it, and had it working in March 2015.
My system measures power consumption and solar power from my solar inverter.
After an overnight of more thinking, I decided to swap the wireless/radio module on the emonbase; it then burst into life and started working correctly, (luckily I had bought a spare emonbase wireless/radio module when I bought my original equipment in 2015).
So i now have a working system again. Thanks.
Just to make sure of any future issues or failures, I have purchased two more emonTX V3 transmitters, and two more emonSD - Pre-loaded Raspberry Pi SD cards from the shop this morning.
This will allow me to experiment without disrupting my now working system.
In answer to your question re was the emonbase OK, I don’t have any other wireless devices on the system. Luckily I do know my way around Linux systems, so I had successfully logged into the emonbase PI, and it seemed to be all OK; however I new that the wireless had failed completely because this has happened quite a lot in the past intermittently, so I wrote a watchdog timer (bash and php) script running on the enmonbase to check every 60 seconds that it received an update from the emonTX V3; if the update failed ,then the script sends a couple of syslog messages to my other Linux box (xubuntu home router) and then the script reboots the emonbase. This script started running in a loop every few minutes during the wireless failure, so I new that the wireless had failed, but I just did not know which end had broken. It turns out that the emonTX V3 was all OK, and the emonbase wireless module had failed.
Hopefully with the new emonSD cards that I have ordered I can build a new/replacement system which will be more up to date, and hopefully I can start to use some of the more recent features that have been added over the last two years.
One of the of the main features I want is to be able to collect my data (take a backup), either off the new emonbase system, or from the emoncms.org website; however the backup works when I get to figure it out?
Presumably I can build a new up to date system to replace my existing older system, and then have the new system just carry on updating my old emoncms.org account using the same api key, so I do not lose any of my last two years worth of data?
Thanks for your help. Cheers.
