🖐 Ahoy! This repository provides hardware and software solutions for communicating with Hoymiles inverters via radio. Our system allows you to easily obtain real-time values, such as power, current, and daily energy, as well as set parameters like the power limit of your inverter to achieve zero export.

There is a fork of an early AhoyDTU which supports MI-Model inverters which should be integrated in AhoyDTU and the aim is to build a library of common functions / methods for both Gen 2 MI- and Gen 3 HM- inverters. We do not know yet what will happen / be supported with HMS-/HMT- inverters hitting the European markets since this year only.

After successful DBus connection, OpenDTU (resp. Ahoy) is accessed via REST-API - simply the /status (resp. api/live) is called which returns a JSON with all details. A sample JSON file from OpenDTU can be found here. A sample JSON file from Ahoy can be found here; Serial/devicename is taken from the response as device serial

Open-DTU Export-Limiter v1.0 This automation enables you to achieve "zero export" / "Nulleinspeisung" with your Open DTU-Powered solar inverter whilst adjusting the output to be as high as possible within the configured boundaries. This can potentially work with any other solar-inverter exposing the necessary entities as well! This automation also requires a device measuring.

OpenDTU Fusion. This board was developed by @markusdd and the help of the OpenDTU/ahoy Discord community. It integrates all the components that are necessary to run OpenDTU on 5.5cm x 5.5cm, namely a ESP32-S3-WROOM-1U module, and the complete RF paths for NRF24 (HM series) and CMT2300A (HMS/HMT series) communications. So this PCB can interface.

Hoymiles offers a solution to do just that with the DTU (pro). There are two variants. One is the DTU-WLite for just under 59€ (incl. VAT) or the DTU-Pro for 249€ (incl. VAT). Wow, I had to let that sink in. Both variants require access to the S-Miles Cloud. Uncool and definitely too expensive. Open source to the rescue 🆘

DTU is the base unit of heat. You need DTU * S pecific H eat C apacity * Mass (grams) to figure out how much to heat something up. Water has an SHC of 4.179 DTU/gram. If you want to heat a full tile (1000kg) of Water by 1 degree C, you need: (1000 grams/kilogram) * (1000 kg/tile) * (4.179 DTU/gram) = 4,179,000 DTU's or 4,179 kDTU's of heat.

Yield Day Correction. By default, the daily yield is reset when the inverter is restarted. This is handled at the inverter itself. On a cloudy day it can happen that the inverter restarts multiple times during dawn. This leads to the effect that the daily yield is already displayed as zero in the evening. If this setting is activated, the DTU.

The DTU is a kind of bridge between WLAN and the inverter's sub-1G radio. In addition to the manufacturer's DTU, there are 2 open source projects for a DIY DTU: AhoyDTU and OpenDTU. The hardware basis of the projects is an ESP32 and an additional radio module. Depending on the inverter type, an nRFL24L01+ radio module is required for the HM.

OpenDTU or Ahoy DTU as PV Inverter in VenusOS. Hi community, inspired by the dbus-shelly-3em-smartmeter from @fabian-lauer, and dbus-shelly-1pm-pvinverter from @vikt0rm, I have created a Github project to usen OpenDTU for Hoymiles and TSUN Inverter API to show PV values in VenusOS as a PV inverter. So you do not need any Shelly or metering.

Steps to build your own DTU. Determine the RF module you need. Get a ESP32 module. Use a power suppy with 5 V and 1 A. The USB cable connected to your PC/Notebook may be powerful enough or may be not. Also the quality of the used USB cable might have an impact. Wire the module and RF module. Wire a optional display.

OpenDTU is a free implementation of the DTU-Protocol used for Hoymiles inverters. My config is based on a HM1200, possibly adjustable to other inverters aswell (mine has 4 Inputs, 2 MPPT trackers, similar to the HM1500, but i would recommend the MQTT-Explorer or similar, to figure that out) Aready discussed in the forum.
