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 device to get a reading into Venus and VRM Portal. Hope you find this useful. Attached are some screenshots and the link to Github: -opendtu
Nice to hear it was not just for me ;-) To your questions:
As My Hoymiles Inverter and with that OpenDTU is only single phase you can only see Voltage and Current of this phase. I cannot say if that is different for 3 phase Hoymiles, but should also work. I just need to implement this. Venus and VRM Portal seem to calculate then the overall Current from all phases. That is why you do not see a current in my screenshot for AC Totals, you cannot write to Total Current or Voltage anymore in dbus. but it should be accurate enough for Victron/Venus and VRM. So for now the code is single phase only.

Currently this is only to pull data from OpenDTU into dbus, no way back from Victron ESS to Hoymiles. This is not my use case, but if that is needed, then please help to add the required code. For now I control the hoymiles from home-assistant.
hello henne, could now finally put my ahoydtu into operation. unfortunately only the first one is displayed here. the calculation does not refer to the total but only to the first inverter. I can't really test it because the sun has made itself quite rare here. Since I don't have a plan from programming, I don't know how complicated it would be to show the inverters individually, such as L1,L2,L2. Or at least read the complete total from the Dtu.
opendtu luft nur auf dem esp32. Wenn du Daten siehst mit ahoy, dann muss es auch da die gleiche URL geben, weil die Frage ich ab. Aber es kann sein, dass diese JSON Datei dort anders strukturiert ist, wie bei OpenDTU. Dort stimmen auch bei 2 Inverter die Summen, aber ich habe bisher immer nur einen Inverter per Serial angezeigt, weil ich nur einen habe.
I have a 1-phase inverter (HM-1500 and HM-1200) together in a DTU. and I believe that the values are not totally taken over here, but only from the first one. or do you have the same setup and split it into "2 phases"?
I'm just playing around with the installation, as I do not have an actual Hoymiles inverter yet. In my OpenDTU i created a dummy inverter with a bogus serial number. The inverter is now listed in the openDTU webapp, but obviously does not have actual data.
However, following the installation instructions for the dbus-opendtu service, I would expect that I should be able to see the openDTU device as a PV inverter in VenusOS, right? Apparently this is not the case however, and I am wondering if my installation is correct.
For instance, I set my log level to DEBUG in config.ini and I would expect to regularly see entries in /data/dbus-opendtu/current.log, but the file does not exist, making it look like the service is not running. How can I check if the service is in fact running?
I'm not able to get a tasmota (sonoff pow) working with generic template. I have uncommented und configured everythink below "[Template]". But there there should be any failure, because it didn't work. Can you or anybody help me?
The code would be ready in further steps to support from a single script multiple REST based devices in a single instance, but we are not yet there. So for now you have to install multiple times. I guess if the merge works fine, we will see a single Instance to support up to 10 different Shelly or Sonoff devices in a couple of weeks.
I have started with 2.80 as VenusOS version and I'm currently on beta 3.0 which works. As we use the official Victron dbus API, it should be quite compatible. I cannot say what is the earliest release that is supported.
The first code change is done and it works with only Template or with 1 opendtu or 1 ahoy and multiple templates. I will push the code later to github and then you can test the branch, before we merge into main.
ich bekomme das leider nicht ans laufen
nach dem ich die IP des openDTU in die config.ini eingetragen habe und gespeichert habe ich einen Neustart des raspi gemacht der Open DTU fehlt leider immer noch.
Please file Bugs, Problems and Questions on github: -opendtu#troubleshooting
Sometime VRM is having issues to show, but overall statistics are OK. So the most important thing is that Venus console works. Please raise an issue.
Maybe this is a stupid question, but as far as I understand Victron is communicating with Fronius inverters to, if needed, lower their output instead of using Frequency shift, in case the system runs on island mode.
Hi henne,
I have also a question:
After installing the software with hoymiles, and getting it to work suddenly i dont have any values in Grid showing. This is for remote console and VRM. (Grid - )
Im using the internal MPII meters, and in console settings i can see the AC input beeing displayed and also i see the AC Out. Everything was working bevor and is right configured.
What is also interesting is that somtimes i have way to many load showing.
For example if the MPII is feeding in energy, its displayed as AC Loads.
I dont know where I went wrong. What do i have to change?
Sincerely Adam
Hi, thanks for this awesome module. I am wondering what happens when I do a firmware update of my Cerbo GX device. Will I need to re-install and configure everything or will it still work after the update?
FACTORY RESET REQUIRED AFTER FLASHING NEW FIRMWARE
Please make sure that you perform a factory reset by navigating to menu System->Reset->Factory->Yes directly after loading this firmware otherwise the device will not function correctly. Make sure that your device profile is backed up before doing this.
Having checked both the UK and USA Sony websites, there doesn't look like a firmware release was ever issued and only updates to IDC and other software is shown. If any updated firmware had been released, then it would still be available to download the same as for the A700/A850/A900. I'm believe that the A200 - A580 (inclusive), that none of those models ever had any firmware updates as Sony at the time just released another model (A200 became A230 etc etc to to the A580) rather than upgrade an existing model with a firmware release (presumably to get a strong foothold into the entry level market in order for budget conscious newbies or existing prosumer/bridge users to buy the brand and thus generate a greater market share much like Panasonic did back in the day of the DMC-FZ3, FZ5, FZ30 etc).
That being said, having checked further, I'm 99.999% positive that there is NO firmware update for the A580, though if you're having any particular issues, then I would recommend sending your cam to Sony who should be able to re-install it, though I would send them an email first as they 'may' be able to send you the original firmware files via email assuming they would do that.
1.Turn ON the camera.
2.Press MENU, Play, MOVIE buttons simultaneously.
3.While Pressing these buttons, turn OFF the camera.
4.Release your fingers, and wait over 30 seconds.
5.Press MENU, Play, MOVIE buttons simultaneously again.
6.While Pressing these buttons, now turn ON the camera.
7.Release your fingers.
There is no hard reset option or method, only a restore to factory settings option which will revert to what settings were when it left the factory and has no other effect, so any inputs you've made will be removed. It's all in the user guide and plenty of references on the web.

I spent today, and most of this evening, developing and testing both a new Picade firmware and a quick and dirty update script which should let you easily get it installed hopefully without even opening up your Picade.
This is all open-source, albeit fairly ugly code. I have tried to make the Arduino sketch as beginner-friendly as possible, with some comments at the top to guide you through things like remapping and turning the Vol Up/Down buttons into extra game buttons.
Installed via SSH without any trouble thank you.
Tested a couple of old arcade button masher sports games before and after and it does appear that the buttons performed better after the firmware update. Cant help with fighting games sorry.
It is probably too late, but have a look at that: GitHub - tbnobody/OpenDTU: Software for ESP32 to talk to Hoymiles Inverters
It works like a charm ! You just need to build the hardware device (easy to do), flash the firmware and
configure MQTT.
@timguy I do not know what are differences between these two projects. Both of them came from discussions from the same forum: Wechselrichter Hoymiles HM-xxxx 2,4 GhZ Nordic Protokoll? - Mikrocontroller.net
I saw that (in GitHub - tbnobody/OpenDTU: Software for ESP32 to talk to Hoymiles Inverters) the Ahoy tool is presented as a related project. 152ee80cbc
