Thank’s for the reply Paul. I have just posted a second query regarding emoncms.org and this upgrade I am contemplating here.. I decided to try a re-install with a new SD card image after a failed update.
At the moment I only have 1 CT though will be getting a second to monitor the feed to sons newly fitted EV charger. I agree adding another CT to the existing emonTX is probably the easiest and cheapest route. I suppose I just liked the look of the emonPi and would find the LCD display useful. I am not sure why 868MHz was suggested at the time but it seems 433MHz is the default and most popular. I would have thought it would also have better range due to the lower frequency. My emonTH is v1 also so I am happy to replace it with a v2. So would standardising on 433MHz be the better option if I do go for the emonPi. I can’t envisage needing more than the 2 CT’s.
I thought emonGLCD got it’s data directly from the emonTX. Therefore am I right in thinking if I replace the current RPi/emonTX setup with an emonPi then I wouldn’t be able to use the emonGLCD as the emonPi doesn’t retransmit data.
