ThingSpeak will accept Hex values as well as ASCII. Depending on how they are formatted, it may interpret the hex values as strings. For example, Cheerlights (channel 1417) contains the string from the color name and the hex code in separate fields. I couldn't find information about Lorabee.send() function in a quick google search so I don't know how it works. I assume it must have the api key correct if you are getting posts to your channel, even if they are zero.
Perhaps you aren't sending valid field information ('field1=')? See the documentation on Update a channel feed to make sure your format is correct.
Also you should try using your browser or POSTMAN to update your channel. This will help you ensure the format is correct for the request. You can use the format shown on the API keys page on the right:
GET https://api.thingspeak.com/update?api_key=WRITE_API_KEY&field1=#xxxx (dont use the GET if you paste it into your browser window)
