I’m setting up a monitoring rig to be installed on a 3 phase ground mount PV system.
The inverter & generation meter is 100 metres from the grid supply meter. So I envision an emonTx + ESP8266 wifi module at each meter location. The emonBase will be located metres away from the grid supply meter. The site has good wifi coverage.
So far so good until I discovered the 3 phase firmware does not allow for pulse counting so …
Question 1: Can the pulse counting logic be incorporated into the 3 phase firmware. If so - what to copy & paste & to where?
Assuming this is not possible then 2 emonTx’s will be necessary at each meter location. The second unit just to do pulse counting. Perhaps the Shop will supply 2 bare bones units – no case/fascias, RF module, battery box or CT sockets.
Question 2: would it be possible to use just one ESP8266 wifi module at each meter location? – the TX outputs from each emonTx being wired together & fed to just one ESP8266 wifi module? – or will the messages get ‘scrambled’?
Any help would be most welcome.
