Hi All,
Looking for some advice on configuring an additional Eastron SDM220 Energy Meter.
Eastron SDM Energy Monitor — ESPHome
I’ve been running 3 SDM220’s for almost six months now with no issues & have now just added a 4th.
It’s on the Modbus line & readable when it is powered up.
What I need to address is that it is reading what we refer to as a Controlled Load for the Hot Water System. So the meter is only powered during the period when the Energy Supplier enables the circuit.
Catch is Home Assistant & EspHome report the meters values as Unknown or NA when the meter is not powered.
I’m lead to believe that I may be able to add a Filter to the Sensor code, so that when EspHome cannot receive a reading from the meter it will pass on the last known value.
Only reading I’d need to pass on in this manner is the Total Usage in kWh,
import_active_energy:
name: "SDM230M Import Active Energy"
Usually this Controlled Load is switched on after 11pm & off before 7am, so reading the usage totals in a dashboard or the EspHome device Webserver is not possible outside that time frame.
Does anyone have any pointers on if & how filters can be used to address this issue?
Thanks.
