Should get tooted out 🙂

Awesome, thanks!

Is there an example of how to send media, for instance?

GOT IT.

If you include a filename in msg.payload.image, it will include the image in the toot.

I have a function node which sets msg.payload.text to a String and then returns msg:

```auto
msg.payload.text = "Hello world"; 
return msg;

```

The output of the function node is connected to the input of the sendMessage node, but the value which is tooted is "undefined". What am I doing wrong?

I don't use JavaScript in functions very much but I think you need to set msg.payload to be an object first

```auto
msg.payload = {}
msg.payload.text = "Hello using function node in Node-RED"
return msg;

```

This woks for me

or

```auto
msg.payload = {text: "Hello using function node in Node-RED"}

```

Many ways to skin a cat

I would be really interested in hearing from people what they use this for. What do you/would you use a bot to send to Mastodon?

I use mine to change #cheerlights if they've stayed the same colour for around 15 minutes.

Used to do it by posting directly to twitter but now I do it on Mastodon via @cheerlights@botsin.space account that cross-posts
