Particle photon integration via particle cloud or MQTT?

Hi

I have a particle photon with a DHT22 sensor to read temperature and pressure. I would like to integrate it with home assistant, just to display the data there. What is the best way to do it?

I have read that it can be done via MQTT, but also the photon can publish json messages to particle cloud or any other endpoint.

What is the best way to do this integration? Has anybody done that before?

Thanks
