Compatible BT temperature sensors

Q&A and troubleshooting

Hi.

It’s getting cold around here and I’d like to add temperature monitoring on a couple of remote PV plants installations, where I already have Victron systems running as telemetry power supply backup.

Because I am currently in the process or replacing LEAD batteries with Lithium, I want to get a basic view on certain temperatures, i.e. outside_temp vs inside_temp vs battery_box_temp. I know Ruuvi sensors are compatible with Victron, however I was wondering whether there are other Bluetooth sensors also compatible or not.

Please elaborate.

Hi
Can’t say what other BT Temperature Sensor would work.

I use RuuviTag BT Temperature Sensor (about 30+ around various outbuildings) on my land, the thing I like about RuuviTag is they also measure humidity and as most of my Victron Equipment is in non-heated buildings is a good idea to keep an eye on humidity aswell as temperatures.

The only (small) issue i have come across is the battery its shipped with doesn’t last long, i have replaced most now with Panasonic batteries, apart from this i think they are a fantastic Sensor.

If you find something else i am always open to trying something new.

It would be great if someone would pick up a project like ESPhome.
Then you could choose what type of sensor you connect to your sensor sender.

ESP32 or equivalent would be a great sender. Could be implemented as Bluetooth or WiFi.

Maybe some way in NodeRed?

EDIT:

So, got a little bit in to the topic:

I’ve got now an ESP sending data to my Cerbo. Can read it in Node-RED.
Question now is: How to get it displayed as a temperature on the Venus Screen?

This is exactly the use case I created dbus-mqtt-devices for. Should be easy to set up if you follow the readme and browse the examples in the sample directory.
