  • the open source heart rate monitor can be connected to an esp 8266 microcontroller
  • in the Arduino code of the 8266, whe can enter the Wifi name of our wifi router and connect to it
  • in the Arduino code of the 8266, we can enter there the ip adress of thingsspeak

ThingSpeak is an open-source software written in Ruby which allows users to communicate with internet enabled devices.[2] It facilitates data access, retrieval and logging of data by providing an API to both the devices and social network websites. ThingSpeak was originally launched by ioBridge in 2010 as a service in support of IoT applications.[3]

it records only one entity at once for testing purposes. For long-time storage you should rely on the InfluxDB component of Home Assistant. With that is possible to store sensor data in InfluxDB.
