Humidity on VRM

HI, I am creating my own temperature and humidity sensor using an Arduino. I am sending reading from Arduino via MQTT. I am able to see the temperatures on VRM but I do not see the humidity value. According the the VRM update on 7th December the Humidity value should be displayed on the VRM dashboard underneath the temperature.

The MQTT topic I am using are:

For temperature: W/<portal id>/temperature/<device id>/Temperature

For humidity: W/<portal id>/temperature/<device id>/Humidity

I can also see the values on the local Venus MQTT (using MQTT Explorer) at
N/<portal id>/temperature/<device id>/Temperature and N/<portal id>/temperature/<device id>/Humidity

Am I doing something wrong?

Regards

Martin

Hi @gone-sailing,

thanks. That explains why you're not seeing humidity. Meanwhile we're at 2.80~41-large-25 and humidity became available with the 2.80~33-large-24 I think. I suggest you follow the "tracker" for new announcements on the large image here: https://github.com/victronenergy/venus/issues/378

You'll find the download link to the dropbox link somewhere in that thread.

Hi, @Stefanie I have the 2.80~33-large-24 installed. SignalK is connected to VenusOS locally via its plugin with the dbus interface and all Victron data shows fine on VRM. I also have a wireless SensESP temperature sensor that sends deltas to SignalK server with a configurable SignalK path (e.g. environment.inside.temperature) - this also shows fine in SignalK's Data Browser. Is there a way to convince that temperature data to display on VRM? I tried various configuration via the Victron's MQTT but with no luck. Any pointers would be much appreciated. Cheers.

I'm running the Venus V2.80-21 Large on a Raspberry pi for dev/test purposes. I don't think there is a later Large version.
