Hi,
I have two emonTHs running, one with an optical sensor for reading electricity led pulses and the other which reads a reed sensor for gas.
I’ve left both running for an extended period of time and I have had to periodically adjust them both however given that I have had to do this I am concerned about the historic data and wanting to fix this so that this doesn’t happen again.
For both monitors I have created virtual feeds which should represent the meter’s current display, it is the offset that I have had to to keep adjusting to bring the live figure back into line.
How best can I go about identifying and rectifying the cause? I believe the gas meter reading with the reed sensor is due to switch bounce but I’m not sure what would be causing the electric meter reading.
The meters I have are as follows:
- Llandis+Gyr E110
- Estler BK-G4M
Below I have attached how I calculate the inputs/outputs. Any advice would be greatly appreciated as I’m currently being over charged by £60 by my current electricity supplier due to a mistake made by the meter reading person so would like to not have any future concerns about the readings reported by Emoncms.
