Hi guys,
i’ve got several meters that cannot be read automatically (they’re outsite of the house without any wifi or zigbee signal available).
So what i did the last years was going to the meters once a month, reading it, writing the value to my telegram bot which then appends it to an influxdb and have wonderful graphs in Grafana.
Since the energy dashboard is available i wanted to migrate this solution to HA.
But unfortunately all my calculations are wrong. It seems like HA doesn’t like it when the sensors value aren’t updated often enough.
What i can see in the developers tools is:
And this leads to very high and wrong consumptions in the energy dashboard:
I’m currently using a telegram bot in NodeRed which writes the data to an mqtt broker, which is then received by HA.
So I’ve got the following questions:
Why is the value going down to zero, when the sensor state hasn’t changed? (Picture 1)
What is the minimum interval in which i have to refresh the values so the data does not get corrupted? I’d assume at least once per hour?
Is there a way to automatically refresh the values (still the old value, but with newer timestamp) using automations? (monthly accuracy is enough for me)
