No, I see that always. It appears to have succeeded.
Still reads 124v
Is that after reloading the .hex file? The source file looks to be correct, can you compile that and load it?
And what about the DIP switch?
It’s OK dip switch was wrong. Sorry to have bothered you!

Hi Robert, I know this thread is old now but another question. Will this older TX3 work with the wifi add on? I am having problems with the radio signal even though it is not a long-distance and no brick walls in between.
Yes - but you may well need to follow the very early release notes which describe the ESP8266 conected externally to the emon|Tx. Using the EmonTx v3 with the ESP8266 Huzzah WIFI module.
When you get WiFI working, you will probably want to disable the RFM module. If the software version is recent enough, that can be done via a programmer and the setup menu. If not, then you’ll need to download the sketch, edit it and re-load the emonTx 3.
Thanks Robert I have only just got back to this. Am I correct in saying I can update TX3 firmware using Pi with latest software with usb lead? The wifi card was bought from the openenergymonitor shop so has the correct software I believe?
It’s said that you can do that, I’ve never tried it so I can’t personally endorse it. The ESP8266 from The Shop should indeed ‘just work’ - given ir receives the data in the correct format.
At this point I guess it would make sense to go continuous monitoring. Is it as simple as loading the cm firmware into the tx3’s and it will work?
I’m still not sure what hardware you have. There are two very different versions of the emonTx V3. The V3.2. used the no longer available RFµ328 module, while the V3.4 has the ATMega 328P directly on the main circuit board. Then there are two possible radio modules, the Hope RFM12B and the Hope RFM69CW. To identify which one of those you have, look here: Learn | OpenEnergyMonitor
When you can say definitively what you have, I can tell you which software will work, or what you need to change to make it work.
Board says v3.2 Oct 2013. That prob explains why it would not update connected to Pi. with rfm12b 868.
OK, The emonLibCM library itself works on all emonTx versions so far (even with limitations on the V4!)
The rfmTxLib can only transmit, but that too will work with both the RFM12B and the RFM69CW. What I suggest is exactly as I wrote to another correspondent only days ago:
Both libraries are documented, but if you run into problems, do ask.
Thanks Robert,
So I have never used GitHub Arduino or anything like that in my life. I hope I can work it out! To be clear. Are you saying that I will also need to change the program as well?
I am 60 yrs old so this kind of thing is a bit daunting!

No excuses allowed - I’m 73. Yes, you will need to edit the sketch. I can do that for you, but I can’t do it immediately, it may well be a week or more before I can look at it. Let me know if you’re prepared to wait, or whether you want to give it a go. Do you have a programmer? And have the Arduino IDE set up? You’ll need both either to load a sketch I send you, or to edit and load your own.
Thanks again Robert,
I have a programmer. I have downloaded Arduino. I can’t get a serial feed from the emontx into Arduino (have downloaded drivers) And I don’t understand how to download from GitHub and get stuff into Arduino libraries. Pretty useless really! Instructions not that clear!

Which instructions were you following? This is my recommendation: Learn→Electricity Monitoring→Using the Arduino IDE
I go to say Jeelib on the GitHub site but I don’t see how/where to download it?
I normally try never to waste my time with Github. If you want emonLibCM and rfmTxLib, here they are:
emonLibCM.zip (132.8 KB)
rfmTxLib.zip (61.3 KB)
thanks you are a godsend. Now I don’t have blue led on usb to uart
That’s a separate issue. Did you follow the 'Learn" pages for installing your Arduino IDE and (if you’re using Windoze) the driver? Did you get the correct driver for your programmer - because The Shop has sold two versions of programmer?
