I have an emonPI, emonTX and Heat Pump Monitor that I want to use together.
All of the devices I mentioned above have CT sensors connected.
If I want accurate Real Power Measurements to be made with all of them do I need a separate 9V AC-AC adapter power supply for each, or is it enough to have one connected to the emonPI because the devices can share the measurements?
If I connect a 9V AC-AC adapter power supply to the Heat Pump Monitor does it also need a separate USB power supply?
Can I use the emonTH for measuring outside temperatures?
If yes how should I place it to make sure it is not damaged by weather?
Thank you in advance.
