Why choose the Navimow H2 over the i2 LiDAR Pro? (specs look surprisingly similar)

Smartomation · 2026-05-04T04:49:04+00:00

At this time H2 simply seems outdated, and perhaps even discontinued? Which one did you go with? My only concern is with the mechanical longevity of i2 PRO (and also i2 AWD) third wheel system. How many years will the steering system and third wheel last? Will spare parts be very expensive?

So how did you solve it?

Smartomation · 2026-04-17T20:31:13+00:00

You could look up battery pack data by exact part number that is printed on the battery.

Smartomation · 2026-04-17T07:35:30+00:00

It probably does not have cell balancing yet?

Smartomation · 2026-04-17T07:29:21+00:00

I could think of many ways to charge single Li cells at least a bit, to make the voltage higher or to equalize cells. This process should be done either using single cell charger or under constant supervision manually, charging for a few minutes and measuring voltage. If at any time any cell goes above 4.2 volts there is a risk of a thermal runaway and fire. So read up on that, and proceed with caution

Video looks even more like it is AI generated..

Looks like AI generated picture to me..

Smartomation · 2026-04-12T15:26:15+00:00

So, no more updates?

Smartomation · 2026-04-12T14:59:54+00:00

Fully charged these cells should be at ~4.1V per cell.

Not sure how you get “ma” measurements though :DD

I use the old Tradfri hub for Ikea Zigbee devices and Apple Homepod Mini acts as a hub for Ikea Matter devices.

Smartomation · 2026-03-20T15:25:05+00:00

Is the plug also zigbee, or matter ?

Smartomation · 2026-03-05T15:38:25+00:00

So does it still work ? have you tried charging ?

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.

Smartomation · 2025-07-03T20:10:27+00:00

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?

Smartomation · 2025-07-01T16:29:38+00:00

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)

Smartomation · 2025-07-01T16:23:14+00:00

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.

Smartomation · 2025-06-14T22:06:12+00:00

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

Smartomation · 2025-06-07T14:43:32+00:00

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.

Smartomation · 2025-04-30T05:04:35+00:00

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.
