All values in the screenshot are integers. So most likely the problem is on the HA side. Try rounding the template value? Did you try the [HA community](https://community.home-assistant.io/)? ---

Not really, I just noticed the errors in log. It’s not something critical I guess. Then I have another question. I can control devices now in HA (and therefor also in Lovelace 🙂). Is it possible to get notfications from Homey? For example, I now get a message on my phone when there is mail. This is a flow in Homey. It would be nice if I could see that same message also in HA. Better say, I want to send messages from flows to HA. Is that something which MQTT Hub supports? If not, will it shortly be supported or is there another way to do this? ---

Witch card are you using in HA for this? ---

Good question. That’s also something I have to find out later. ---

Hi Thanks for your great app , new to this MQTT Can i add my blue iris trigger with your new MQTT device / Discovery ? ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/2X/e/ee0c26ee94f79b33c8fe76fa423f590805889bbf.png) Thanks ---

@djesko That’s what it’s build for 🙂. It probably won’t show up on auto discovery, unless it supports the homie3 convention. But adding an MQTT device manually pointing to the topic in the screenshot should work. Did you try already? ---

did try but dont know what to write in the discovery topic 🙂 ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/2X/4/41f339e1c5c1d6c94e84d09be6908de51aa471e0.png) ---

Just add an mqtt device, you know the exact topic after all. ---
