Wireless and battery powered temp sensors: the Ruuvi

Something quite new, and far more popular then I (Victron) anticipated to be honest: the support for the Ruuvi temperature sensors. Being powered by a small coin cell in the sensor, as well as wireless, they are super simple to install. And as such perfect to remotely keep an eye on your yacht or cabin in the winter. Or fridge or freezer temperatures, and so forth.

I have installed and am using some myself as well, and they are great. Less stress about pipes freezing up, as well as mould growing: it also reports relative humidity.

Here is a picture showing the sensor, and the reported data:

Here is how the data looks on the VRM Portal:

• To read data from the Ruuvi sensor, a Bluetooth USB adapter is required. For CCGX, Venus GX, and also for the Cerbo GX. A list of suitable and tested Bluetooth USB adapters is available in the Victron Venus 2.80 Blog posted on 31/01/2022.
• Per v2.82, multiple Bluetooth USB adapters can be installed and will all be used to read data from the Ruuvis. This is nice, as it allows expanding the range by using a USB extension cable.

See the documentation for more details about this feature.

Controlling a relay on temperature

The relays on the GX device can now be controlled by temperature. For example to switch a fan, or heating pad. Here are two screenshots showing the configuration:

![Display of the Cerbo GX on how to control the cerbo temperature relays using the input from the RuuviTag In above example, the second relay will switch when the temperature in the engine bay rises above 45 degrees, starting the fan. And it will switch off once the temperature drops below 40 degrees C.

Both the first and the second relay can be configured to be controlled by temperature. And two sets of conditions can be configured, also for the same relay.
