In this tutorial I would like to show you how to read out the data of a Hoymiles Microinverter with an OpenDTU and corresponding Homey apps via MQTT. My equipment: - Homey Pro (early 2023) - [Hoymiles Microinverter HM-1500](https://www.hoymiles.com/de/product/microinverter/hm-1200-1500/) - [Diamex DX-DTU-Klassik](https://www.diamex.de/dxshop/DX-DTU-Klassik-mit-kleinem-OLED-Display-096-242-cm) incl. [OpenDTU](https://github.com/tbnobody/OpenDTU) software **Disclaimer** As I’m not an IT expert and I mainly learned about MQTT myself, it is quite possible that I didn’t take available safety features into account or didn’t take them into account correctly. Anyone who uses this tutorial acts at their own risk. I take no responsibility for any security problems. Experienced users can always make suggestions to improve security. I would check these and update the tutorial accordingly if the integration is still working. # Requirements > **Summary** > > - Homey Pro > - Hoymiles Microinverter > - OpenDTU or AhoyDTU > - [MQTT Broker](https://homey.app/en-de/app/nl.scanno.mqttbroker/MQTT-Broker/test/) (Test version v3.0.4) > - [MQTT Client](https://homey.app/en-de/app/nl.scanno.mqtt/MQTT-Client/) > - [Device Capabilities](https://homey.app/en-de/app/nl.qluster-it.DeviceCapabilities/Device-Capabilities/test/) (Test version v2.15.4) > - [MQTT Explorer](http://mqtt-explorer.com) software/app for PC/Mac > > Instead of the _ **MQTT Broker** _ and _ **MQTT Client** _ app, the [MQTT Server](https://homey.app/en-de/app/net.weejewel.mqttserver/MQTT-Server/) app can also be used as an alternative. # Configuration ### MQTT Broker > **Summary** > > - Port number → 1883 > - Also allow unsecure connections → ☑ > - Disable User Authentication → ☑ > - Disable Password Hashing → ☑ > - Create a user, e.g. _Homey_, with password > → Save and start the broker > > ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/8/9/8981287c759cc30faefbec23241ba60c58577873.png) ### MQTT Client > **Summary** > > - Enter IP Address or DNS → fill in Homeys IP address, e.g. 192.168.1.7 > - Enter Port Number → 1883 > - Disable Certificate Checking → ☑ > - Username for the Broker → fill in the username created in the _ **MQTT Broker** _ app, e.g. _Homey_ > - Password for the Broker → fill in the user password created in the _ **MQTT Broker** _ app > - Use LWT → ☑ > → Save > > ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/3/b/3baa65e3376fedc5146bff5864b84a447f45c66d.png) ### OpenDTU > **Summary** > > - Open Settings → MQTT Settings > ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/c/c/cc2e8600c6ba218705ac3850e3471252e96676db.png) > - Enable MQTT → ☑ > - Hostname → fill in Homeys IP address, e.g. 192.168.1.7 > - Port → 1883 > - Username → fill in the username created in the _ **MQTT Broker** _ app, e.g. _Homey_ > - Password → fill in the user password created in the _ **MQTT Broker** _ app > - Publish Interval → 5 seconds > - Enable CleanSession flag → ☑ > - Enable Retain Flag → ☑ > → Save > > It should look like this: > > ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/0/d/0da3ea754acd1264f90b987178b0e934274561b3.png) ### MQTT Explorer > **Summary** > > - Add new connection > - Name → you can choose a name for the connection.

I have 2 micro inverters with integrated WiFi (HMS-2000DW-4T) and on the OpenDTU page it says that they are not supported (All inverters with integrated WiFi which can be identified by the “W” in the name (e.g. HMS-xxxW) are not supported by OpenDTU). Is there any other solution? ---

That’s right, they aren’t supported by OpenDTU and AhoyDTU. But I don’t know if there is an other way to integrate them, sorry. The only thing what comes into my mind is to use a SmartPlug or an in-wall module to get the energy consumption. ---

Hi @Senad_Aruc, I’m glad that @Peter_Kawa was able to help you. It may be because the “Exclude from energy” switch is set to “Yes” in the AVD’s advanced settings, but I’m not sure. What is more likely is that after adding a device, it takes a while for the values to be displayed in the Energy Dashboard. So please check the setting and be patient. Values should be displayed in the Energy Dashboard by tomorrow at the latest. ---

I can’t tell you why, but I think ticking the “create real field and flowcards” boxes for both power & energy sensors might be the difference. ![1000049180](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/5/b/5b76b597cabd523103568b9c5c80e2b8cf1b3a1a.jpeg) ---

About the top right indicator: Your “Home” isn’t using any energy? Man, that energy thing is the worst product ever made by Athom. In my humble opinion that is. And “of course” there’s no logs available to discover what’s going wrong? ---
