Does anyone use this cool project? I believe someone needs to make an integration to home assistant. It will surely replace uptime-robot.

I am also interested! 
Iāve seen there is actually such integration already using something called Apprise:
In Uptime Kuma, select notification type: Apprise (it will show if you are running the docker version), then see this: https://github.com/caronc/apprise/wiki/Notify_homeassistant
I just set this up and itās technically working but the notifications only show in the UI and app in the notifications section and not as a push notification from home assistant as I would have expected (and wanted). I was searching to see if there was an option or flag I missed which is how I stumbled across this thread.
Anyone get notifications from Uptime Kuma to HA and are able to have HA send the push notification?
FYI - Iām working on a native home-assistant integration for this 
Iām not sure when it will be finished, but i do have a working prototype - i just need to clean it up and make it acceptable to the core devs who will need to approve my pull request.
Iām guessing it will be included in 2021.12

any hints on how it will look like?
Iām using the āwebhook notificationā from Uptime Kuma. Works perfect and since an automation is triggered, this automation can do whatever Homassistant is able to doā¦

Iām not very familiar with using webhooks in this way. Does it create an entity for each Uptime Kuma monitor? If so, could you provide some details on how to setup webhooks in homeassistant in order to expose an entity for each uptimekuma monitor?

Each monitor in your Uptime Kuma instance will be exposed in Home Assistant as a Binary Sensor entity.
Using a lovelace āhistory graph cardā you can easily get a similar view that you would have from the /stats page in Uptime Kuma:

No, no entity will be created. Itās just a trigger for an automation. If you want to know more about webhooks in Home Assistant, these videos from SlackerLabs provide very solid infos about it:

Gotcha, Thanks 
Webhook triggers are pretty neat - I hope they continue to be adopted by more services.
I like itā¦ hope to see it soon on HA

Iāll be submitting the merge request in the next day or so, so hopefully weāll have it for 2021-12

Nice work! I ended up using the built-in MQTT functionality in Uptime Kuma to get data/state into HA so that I can then send iOS push notifications to my phone when things go down/up. Seems to be working very well so far. I donāt really have a need for the GUI though Kumaās is pretty clean. The notifications are nice though as I have monitors for HA that looks for text in the web front end, services via monitoring service ports for things like influxdb, MQTT, etc. very nice little package. Hereās a little sample I snapped before I finished the logic to remove the trailing square brackets from what Kuma publishes over MQTT.
How were you able to use MQTT to send the states to HA?, I donāt see MQTT as an option for notifications.
Use the apprise notification method and enter a MQTT endpoint. See the GitHub docs for the format. Iām not in front of a console at the moment.
any chance you could explain this a little more when you get a chance ? im struggling with this right now, was this auto discovered in HA or did you have to manually create sensors for these?
I donāt do anything with it in HA, itās all external. Kuma to MQTT via Apprise and then MQTT to NodeRed which calls the HA notify service to send notifications to my phone. If you wanted the data in HA then yes, youād setup MQTT binary sensors. Re Apprise, supposedly itās built into Docker if youāre using the Docker install of Kuma but my Kuma and Apprise are installed on a VM, not Docker so that might differ from your install.
I set this up today. My notification flow is slightly different to @rjchu as I havenāt deployed apprise (yet). Instead I used the webhooks option in kuma.
You can automate off this using the standard home assistant automations or, in my case I used the nodered companion component - GitHub - zachowj/hass-node-red: Companion Component for node-red-contrib-home-assistant-websocket to help integrate Node-RED with Home Assistant Core.
From there I output to the android notification service on my phone.
