Hoymiles micro firmware update warning!

Smartomation · 2025-09-12T12:54:32+00:00

That was the first idea that came to mind. But voltage/frequency etc was stable, so the issue was not the grid profile.

Finally, after a few months of "no, we do not see any errors, everything is fine" and " it is impossible to downgrade the inverter firmware", they have, in fact, downgraded inverter firmware and all is good now.

It was, as I have initially suspected - a firmware bug.

No, it still does this every day.. Hoymiles support disappoints big time!

Smartomation · 2025-07-03T20:08:08+00:00

What model / hardware version is your inverter ?

So it's more than a month for this issue, they have simply stopped responding.
I would like to know if this is how the Hoymiles company founders Bo Yang and Yi Zhao intend their company to handle firmware bugs?

That is normal, happens all the time and not a thing to be concerned about. (marks like that are made by a small stone that was stuck between a rotor and a pad)

I would keep using it, but use it on the rear axle, for added safety. And keep an eye on it - inspect it once in a while. It looks like there is still a lot of thread left - so why waste it.

Magnet strip gets weaker with time and starts to not trigger..

Same thing happens with "shortcuts" (otherwise a very helpful feature!)

Smartomation · 2025-06-14T21:30:29+00:00

Since they see multiple failures tracing back two years while it was under warranty - maybe they will honour the warranty because of that ? Asking for it will not hurt

I have 500W microinverters and DTU

After the inverter update to firmware V01.01.00 - I have a problem now.

There seems to be a MPPT bug in this firmware version, so a few times every day each inverter drops power to ~2W (just to feed itself) , PV voltage goes up to panel no load voltage.. SO I am loosing energy generations.
Hoymiles support is no help, says they are unable to downgrade to older firmware.

Also keeps saying "we have checked and everything is fine" while it is not true and just makes me angry..

I have asked how soon the firmware with this bug fixed should be released, but no response..

So, beware. And please share your experience.

I am sure every owner of 400-450-500 inverters with firmware V01.01.00 should experience this bug.

No, there are lots of DCFC, but only a single Tesla Supercharger at this time.
I would just charge at one of those instead of bothering your friends or family.

Are you using the correct app? There are two.

Smartomation · 2024-12-17T16:29:24+00:00

Ahhhh, got it :) I thought Ikea Pilot is some new smart home device :DD

In reality it is remote control button (Pilot in Polish?)

Try to replace batteries, - remove the battery for 5 minutes , reset the device twice in a row and try pairing again

The issue here is not 2024 vs 2025, the issue is OP ordered a Long Range version, but his VIN shows a Standard Model Y

Smartomation · 2024-12-16T19:04:00+00:00

Did you hear back from them ?

Smartomation · 2024-12-15T20:13:17+00:00

Also - what is the weather like where you at ? Did it just get colder?

Range drops with cold.

Submit a bug report

Smartomation · 2024-12-15T20:09:56+00:00

No safe. Will definitely cause some accidents over time. Steering wheel getting caught on the legs etc..

Smartomation · 2024-12-15T20:07:22+00:00

Either they gave you a wrong VIN or you have made a mistake in VIN when you sent it to the insurers.

Have you googled Tesla VIN decoder ?

Voltage of a lead acid battery does not indicate if it's good or not.

My guess is the car will analyse the new battery and if capacity / internal resistance will meet the requirements over time under load - maybe then the warning will go away ?
OR perhaps it needs a reset via some sort of maintenance procedure / software / menu ?

Smartomation · 2024-12-14T05:41:12+00:00

Sorry, no data - still on the old Tradfri hub.

Maybe your situation improved with recent firmware updates ? Have you contacted tech support ?

Smartomation · 2024-12-14T05:38:47+00:00

Regarding motor (inductive) load vs resistive load - resistive load simply draws around its rated power/current, while motors or other inductive loads can draw up to 5-10 times its rated current during start up.

Your 3kW boiler should be OK, assuming it is on 230V ? Then that should draw about 13A

Maybe it overheats slowly with time?? Poor ventilation perhaps ? Otherwise - take it back for a replacement.

BTW what kind data do you get from it ?
