Hi,
I have a Victron temperature sensor attached to the Cerbo, I can see it in VRM portal and I can see the temperature, however there is no history or graphs.
Do I have to set it to start logging? Is it possible?
Thank you

Temperature sensor data logging with Cerbo - Possible?
Awesome, thanks mate I must've missed it.
Where would I set email alerts for high/low temperature values?
Extra points if you can tell me if/how I can feed that data in to Home Assistant.
Thanks again
Also in VRM -> settings -> alarm rules Then select the temperature device.
Home assistant I'm not sure what the preferred option is for that community. (I use openhab).
I would've guessed they just read from victrons MQTT server details here:
GitHub - victronenergy/dbus-mqtt: Venus OS service mapping the D-Bus on Venus OS to MQTT
I also find this link useful to find out what the available topics are. The MQTT topics follow the same pattern as DBUS paths
dbus · victronenergy/venus Wiki · GitHub
For example it would be
/N/{VRMID}/temperature/{deviceID}/Temperature
where you replace {VRMID} with you vrm ID (can find in gx device's vrm settings)
and {deviceID} with the temps sensors ID.
However I've seen a lot of folk on here prefer modbusTCP to get data into homeassistant. You can find guide for that here:
GX Modbus-TCP Manual [Victron Energy]
As well as link to list of modbus registers in excel format here:
Technical information - Victron Energy
Happy to help further if you need a hand with anything
