Wanting to use an emonPi shield at 868MHZ,
Present system as setup in 2015
emonGLCD v1.4 with SolarPV sketch
emonTx v2.2 for monitoring 7 temperatures
emonTx v2.2 20*4 LCD Power and temp display, plus reporting room temp X 2
emonTx v3.4 with emonTxV3_4_continuous_kwhtotals
Also one of Robin’s Mk2 routers, 5a sketch
Raspberry Pi + emonBase RFM69Pi X 2 Node 15 and 16
All at 868MHz
Recently purchase an emonPi shield + case and LCD display, NO RF
I was thinking I could add a 868MHz RF module, and just make the necessary changes in the sketch and emonHub, but it now looks more complex than that.
In emonpi-2.9.2>Atma328>firmware>firmware.ino I have found this:-
//----RFM12B / RFM69CW SETTINGS----
and in emonpi-2.9.2>Atma328>firmware>rf.ino
case ‘b’: // set band: 4 = 433, 8 = 868, 9 = 915
Would the firmware.ino need editing to 868MHz, and the part in firmware>rf.ino would then be configured in a setup procedure?
Then emonHub would need to be edited?
If anyone could confirm or correct me it would be appreciated.
