How to save money on Azure Event Hub Basic Throughput

I don't quite understand how Microsoft is calculating my Evenhub costs.

The current setup is: I have a Raspberry PI Zero which sends messages once a minute via https to an Azure IOT Hub and the IOT Hub routes it to the Event Hub. One Message seems to be around 2kb big as seen in the Event Hub Throughput Graph. The Eventhub is then read by Elastic Logstash which uploads the messages into Elasticsearch. So we have 2kb/min incoming and outgoing traffic.

A raw message looks like:

{ "humidity":98.86653465006785,
  "@timestamp":"2021-02-12T01:07:05.883Z",
  "pressure":1035.0542695256731,
  "@version":"1",
  "temperature":-10.694375312741613
}

This is only 149 Bytes in total. I got the number through putting it into a txt file and taking a look into the properties.

My Service is now running since three days and already consumed 0,68$ which seems too much in my opinion.

If I interpret the MS Azure Event Hub pricing page corectly it charges me with 0,015$/h for generating traffic at 1MB/s incoming and 2mb/s outgoing

Did I make a mistake or is there a way of lowering the costs?

For anyone looking up to this question, there is indeed a way to reduce the cost of operation. In my case I used the IOT Hub to redirect the messages to the Event Hub, which is nonsense in my case. The Event Hub is totally unneccesary for this. You can use the IOT Hub like an Event Hub to get your messages.
