Hello all, Newbie and first time poster to the forum and I’m soo not technical. We’ve had a emonPi connected to a couple of emonTHs for the last couple of months (all out of the box configuration), but I’ve just moved to try and get our newly installed solar to be be monitored via a emonTx, our ele…

That does indeed look a lot more plausible. [image] Tony: previously I took the comment the “You can now allocate the c.t. to any phase” too literally Can you explain that? It might well be that I need to change the wording. My problem is I know what I meant - you do too, now, but what I wan…

Welcome, Tony. I take it that you are using the three-phase sketch - is that correct? From the look of the picture, I strongly suspect that isn’t the case. If you’re not using the 3-phase sketch, the emonTx will never read anywhere near the correct powers because of the phase relationship of the th…

Many thanks for the reply Robert, apologies for the delay I’m working away at the moment and won’t be able to anything until I return home, but I shall endeavor to setup the CTs with the details in the 3-phase sketch documentation above. Essentially when I purchased the emonTx I asked for the lates…

[image] Tony: firmware, is this the same as a sketch “Sketch” is Arduino-speak for the user-supplied software that customises the device. If you have a programmer, on power-up it will print details to the FTDI port which the Arduino IDE can display. If you don’t, the LED on the main board (I…

Hi @Robert.Wall I’ve done as recommended. I’ve purchased a USB (FTDI) connector and connected my laptop to upload the latest sketch (took me a while, learning curve and all). This is what I am seeing now, it is different, but I’m thinking it’s still not right. [second%20attempt] The big dip aro…

Only you know what you were running at the time, but that doesn’t look right to me. Did you extract the .pdf documentation file from your download, and did you follow the instructions in the “Installation” paragraph there for identifying the phases and setting up the c.t’s? (‘Turn everything else o…

Hi @Robert.Wall , Ok I’ve followed the instructions (previously I took the comment the “You can now allocate the c.t. to any phase” too literally :slight_smile: ). I disconnected everything and identified spikes in power as I turned a kettle on (seeing positive spikes) for each phase and when the so…

@Robert.Wall , I think I took it literally to mean that once I’d uploaded the new 3-phase sketch, allocating any CT to any phase negated the need for calibration (the isolation of each phase for power spikes). Many thanks for you help throughout this Robert, I know I asked some really basic questio…

OK, thanks. I really don’t think I can make it much clearer. Step 3 says put all the c.t’s onto your test load, then finally step 6 says allocate them to the correct phases, do a final check and then move the c.t’s to their final home. [image] Tony: I know I asked some really basic questions, b…
