Heart Rate Monitoring
Can we get heart rate module to get input from Raspberry Pi Sensor or from any IOT source
@piyushtanksale00 - I do know that the MMM-Fitbit module includes a heart rate statistic. The module is a little unreliable due to Fibit’s weird API. But once you get it running you can get all sorts of fun fitness information from it.
Depending upon your coding skills, just about anything with a REST API can be displayed on the mirror.
