Ghost readings from Aeotec SmartSwitch

I have three Aeotec SmartSwitch 6 plugs. They are connected to a heater and turned off, however once in a while for very brief periods two of them will report “ghost” readings of ~ 0.5 Watts and 0.05 Amps.

Has anyone else noticed something similar?

Completely off topic: what do you use for graphing?

The graphs are made by “Grafana” ( and the data is logged in InfluxDB (

It was pretty straight forward to setup on ubuntu, since both grafana and influx had a ready-made package. I wouldn’t advise installing this on a Raspberry Pi.

@kirichkov why not on Pi?

It’s write-intensive and you’ll shorten the life of the SD Card considerably.
