MQTT

Hi everyone,
I am teacher in agriculture and I want to form students to the use of TTN to connect sensors in the fields. For that, I have a Raspberry pi and I installed on it influxdb, grafana and NodeRED.

I want the students to create an app on TTN, then send their API keys in order to parameter a node “MQTT IN” in Node Red, then store the info in influx.

I was just wondering if ther is a limit of MQTT IN node ? Is it a problem if I have 50 MQTT IN nodes, each one configured for each of the 50 app in TTN ?

thank you !
