Can't get Ruuvitag plugin to work in Signal K

[traveler]

I've had good luck getting Signal K plugins to work, but I'm stuck with the signalk-ruuvitag-plugin. I'm using current Open Plotter on a RPi 4B.

I am able to answer my own question. Out of the box, a Ruuvi tag displays data to an iOS device but needs a software update to log data to an iPhone.    [https://ruuvi.com/software-update/]

My updated Ruuvi tag was finally identified by the Signal K plugin, but it took maybe 12 hours to show up and it never sent data. 

A second Ruuvi without updated software works as expected. It appears Ruuvi will start shipping tags with version 3 in May. This may affect using the Signal K plugin.
