To increase the information about power / energy consumption in my house I would like to track as well the power consumption of my Synology DSM NAS.
Hence, I would be very happy about a sensor that provides information about the power consumption.
Ideally absolute values (W) would be perfect
The Synology DSM GUI shows CPU percentages (%), if these would be provided as a sensor(%) it could help as well to derive the power consumption.
For this I would take some datapoints using a powermeter (socket) and create a power sensor using PowerCalc integration.
Synology DSM integration already provides CPU consumption, so you have already available what you request for. BUT, power consumption in NAS systems (especialy with larger number of drives) is not really proportional to CPU consumption; energy consumed by spindle drives might be signigficntly higher. Reagrding direct sensor for power consumption; I do not think it is possible - DSM API does not provide such information, so it is not possible for integration to provide such info back to HA.
The only possible solution I can see is to use power meter an individually profile your NAS, potentially combining idle consumption from drives only with increased consumtion under heavy load (CPU %) and using Powercalc integration to create such sensor,
Thanks a lot! @mirekmal
I can’t explain why I overlooked the CPU sensors of the Synology integration. Thanks for making me looking again and noticing that they were deactivated.
Now I will measure power consumption via a meter, and try to find a relation to the CPU-utilization. It will not be highly accurate, but better than nothing.
