[APP][Pro] Todoist

Adds Todoist integration for Homey.


  • Create tasks (in project, with due date, with due time)
  • Fetch tasks
  • Respond to task events (completed/uncompleted for now)
  • Exposed API for HomeyScript (example)


I’ve kept it very basic but Todoist has alot more features which can be implemented in the future if there is any interest.

Dear Jero,

will it be possible in the future to create dynamic due-tasks?
Right now I can only create a static time and date card for due. But it would be very nice to create a task in the future based on events at my home. (e.g. my plant sensor registers a low level of water and creates me a task in the evening to water the plant).


Yes, that is a good idea. I might be able to create a card that accepts a token as a date/time (basically the default text input). Would that suffice for your use case?

Only problem I see is you probably want to add +1 days/hours to the actual event. Another option to explore might be the due_string Todoist supports e.g. in two hours.

This works pretty well and it errors on faulty dates. Defaults to your Todoist language setting and timezone.


Released a test version (v1.1.0) that has this card. Let me know if you find any issues.

You are unbelievable. Thank you very much for such a fast reaction.

The due-text ist working fine, and does exactly what I expected. The possibility to use a variable from the logic part is also great in case of a calculated date or time.

Thank you very much!

Dear Jero,

I just have a new idea for playing with Todoist.

Would it be possible to mark a task completed when a sensor value changes?

The moisture of a plant is below X% I creat a task for Todoist. If I give some water to the plant and the value rises above X% I want to mark the task in todoist completed by Homey.

Or the battery of a sensor is below X% - new task to todoist. After replacing the battery the task can be marked as done.

Would this be possible?


Seems possible yes but I only see this working for a task that is somehow memorized in a Homey variable or something.

The task creation would have to store the ID somewhere and the other Flow has to mark this ID as completed.

So maybe a card Create a task ... with reference id: <my_reference_id>. And another card with Complete a task with reference id: <my_reference_id>. Only problem would be if the Flow with the first card is executed multiple times you could overwrite a not completed task. Your reference id in this case could be something like battery_level_low_device_1.

Some problems I see is statuses flipping quickly for some reason resulting in spamming complete and create.

I could give it a try next week to make something user friendly if I have some time.

I’ve exposed the API so you should now be able to do this with HomeyScript. Currently available in v1.3.0 (in test https://homey.app/a/nl.jwienk.todoist/test).

const app = await Homey.apps.getApp({ id: 'nl.jwienk.todoist' });
const userId = 1; // get from await app.apiGet(`/users`)

// https://developer.todoist.com/rest/v1/?shell#create-a-new-task
const createdTask = await app.apiPost(`/users/${userId}/tasks`, { content: 'My task' });

// global tag/token
await tag('Task ID', createdTask.id);
// or HomeyScript specific global
global.set("taskId", createdTask.id);

// from other script
const taskId = global.get('taskId');
await app.apiPost(`/users/${userId}/tasks/${taskId}/close`);

I would like my flow to check if there is a task already in my list with the same text. For instance, every sunday at 10.00 create a task that is “water the flowers”. However, if there already is a task called “water the flowers” it shouldn’t create a new one.

Is this possible?

It is possible with HomeyScript right now not sure if that is an option for you. I could add a Flow condition that allows you to check on the name of a task in a specific project.

Hello Jero, thanks for your quick reply!

Wow, that would be amazing! You are right, I don’t master Script, I looked at it and understood nothing!
What happened with the question from someone else, asking that a certain value should mark the task as completed? That would also be great!
For instance, if a task is “Empty the washing machine”, then a energy value from the machine should check the task as completed because obviously if the machine is running again it must have been emptied. I tried to figure something out but without success.

Hello Jero,
Is it possible to do this in a way that doesn’t require HomeyScript?

I had something in the works but not finished and I’m in the middle of moving so rather busy. Will not have any time for 1/2 weeks.

Oh, I wish you the best with your new home and look forward to talking more about this when you have time :smiley:

Hello Jero,
I hope you like your new home. I’m curious regarding the project, any news?

Sorry for the late response but I’ve create a test build with 2 new cards Todoist | Homey let me know if they work for you.

Hi Jero,
It works perfectly, thank you so much! I will continue later today to do different set-ups and if I come up with any new ideas, I will let you know.
