Thank you @Robert.Wall, @Bill.Thomson for your responses.
@Robert.Wall, your suggestion for a serial to usb converter had me scratching my head. All I could think of was the old RS232 usb to serial converters you would use to configure a Cisco network switch. Was wondering how I’d connect one to the other! I started to take a look around amazon and found these, which in my totally inexperienced judgement seem like they’d fit the bill when compared to the wiring diagram for the RFM69Pi:
I did stumble across this post and a member had created this which was also a consideration.
Whilst as feasilbe as they seem, I was looking a more off the shelf solution and @Bill.Thomson seems to have met that. Unfortunately the link Bill provided would have incurred import charges as I’m in the UK. I did however find a European seller and for the item plus delivery you’re talking roughly £30 all in, the difference in price is nothing to write home about between it and the usb to serial converter + the RFM69Pi hat. Taking a more indepth look it seems that the one I just linked to was referenced in the post you linked @Bill.Thomson
I’m still on the fence about using an emonTx with a CT & Pulse sensor over an emonTH with a Pulse sensor and with that I have one final question as I can’t seem to find it, I see than an emonTH reports over 4 years. What sort of battery life can I expect, within reason, to see with an emonTx with two sensors?
Thank you for your help thus far.
