I’m new to the community of OEM. I have a Hitachi RASM-4NE heat pump (11kW monoblock) connected to panel radiators. I have an energy meter for the heat pump but it’s time to upgrade the monitoring system, for more analytical measurements (COP and water temperatures). In the following drawing is the configuration setup which I thought.
Let me do a quick rundown and how i thought it.
3 phase energy meter for the heat pump. Not with CT clamps. Similar type as SDM120 (with Modbus communication, maybe SDM630?). Energy meter will be connected to EmonPI.
Heat meter (Kamstrup 403 with 240V power supply) which will be connected to EmonPI. I assume that flow and return temperatures (measuring points 1,2 in drawing) will be measured and transmitted from the heat meter?
Five (5) DS18B20 temp probes for measuring point 3 (buffer tank temp), points 4 and 5 (flow/return temp of the 2nd circuit), point 8 (boiler temp) and point 9 (external temp). All these will be connected to EmonPI.
Two (2) EmonTH with encapsulated DS18B20 (points 6,7) sensors for measuring temperature of the flow and return radiator header. The reason for using EmonTH is that the radiator headers are 20m away. EmonTH will be connected to EmonPI with an RF signal.
Energy meter for the circulating pump. This could be a CT clamp directly connected with EmonPI.
So, this is my approach and based on this i would like to see if this configuration is feasible. Any thoughts/suggestions are appriciated.
Thanks in advance,
