Reporting Battery Level

@Fat-Fly Nice, interested to try this also.
Any idea how long the batteries will last? Electricity meters tend to blink quite often, so not that much sleep..

At the moment i try this with 2xAA recargeable batteryes but no luck. Gnd and vcc pin. Not working , not reported. if i find batterys.... I search. All remotes is AAA :( 2.68volts from recargeable AA's. where is the fish ?

[Fat Fly]

From recargeable 2x AA and 2,68V not working.

I bought 2AA batteries. Working.Domoticz devices page report battery level 3. How to see battery level graph ?

@Fat-Fly to report battery voltage you have to create a S_MULTIMETER sensor and send the voltage with V_VOLTAGE.

Sendbatterylevel only changes the battery level in Domoticz in % and can not be shown separate.

Tot use your arduino with low voltages you need to change the fuse settings (BOD) with an ISP programmer.

How to i do this ?

@Fat-Fly I will post some code later when I get to a pc. :eyes:

This is great. I do not find from google search. My mother tongue is Estonian :)

@Fat-Fly "Estonia: Between East, West and the World" ;-)

These are the lines of code which should do the trick... you need to put them in the right spot yourself

#define VOLTAGE_CHILD_ID 		5

MyMessage voltageMsg(VOLTAGE_CHILD_ID, V_VOLTAGE);	// Node voltage

gw.present(VOLTAGE_CHILD_ID, S_MULTIMETER, "Battery " );
	
float voltage = vcc.Read_Volts() ;
gw.send(voltageMsg.set(voltage,2));				//send battery in Volt

Estonia between world and russia. :)

@Fat-Fly I am not sure how you intend to arrange your electricity pulse meter reading, but in my case I had to wire Pro Mini 5V to mains or otherwise recharge a battery every 5-7 days. I think you can do the total kWh and putting Pro Mini to sleep, but you cannot have total consumption kWh and current consumption kW with sleeping.

Yesterday this not working. KW reader is too away from gateway.My house is lenght is 22m. Electricity meter is one end of house and gateway is center house. can i use repeater on something other. I use for this nrf with antenna.
