PSA: TRMNL OG charging time is longer than you think

Should anyone care - or have forgotten to read the manual - the green light doesn’t mean it’s charged. It means it’s successfully charging.

Using a USB monitor, from “please recharge” to full, it takes 6 hours 45 minutes. The unit only pulls 500mA so it’s slow. But you’ll see the green light appear and you’ll think it’s charged - it isn’t; it is still taking a charge for a long time to come.

Total charge that went in was 2700 mAh which looks about right for this unit (apparently a 2500 mAh battery).

The maths would suggest that it should take at least five hours to charge, given the unit’s 500mAh charge cap, so this all looks about right.

Anyway - the point is that it’ll take more than six hours to charge which you may feel is quite a lot slower than you expect.

Sungrow iCloud - what does 'revenue' mean?

I've put in the electricity tariffs into the system, but this seems to show me earning revenue when it's still dark. (I have a battery, but it's not sending power to the grid).

I think today I've earnt $0.10 from my feed-in-tariff; and spent $0 in electricity from the grid. That should mean I've earnt revenue of $0.10.

Is this really showing me "this is the money you would be spending if you weren't using solar and a battery"?

Sungrow iSolarCloud - checking my maximum grid import power limit

I'm in QLD, Australia, and I gather that we have a maximum grid import limit of 14.5kW.

I've set my new Sungrow system to "forced charging" between 11a-2p where I get free power from the grid. This is also when my hot water and pool pump run. So, as you can see here, on this day, the system was pulling 12.8kW from the grid - about 6kW load, and then a further 6+kW for the battery charge.

I can't see anywhere in iSolarCloud to suggest that there's a maximum set - although it does seem to be maxing out at 12.8kW to me. Is there a maximum grid import set in these things automatically? I'm a bit worried I'll pull too much from the grid, and things will melt/trip...

iOS 27 - issues

I appreciate it’s a developer beta, and things break.

But for me, Bitwarden’s autofill into a browser appears to break, removing the keyboard and stopping access to paste (quite useful for TOTP).

I’d be interested to hear if it’s just me: or whether iOS 27 doesn’t quite work with Bitwarden for others.

What’s cheaper - Wise or a no-fee Mastercard?

Just double-checking my workings here.

I have a no-fee Mastercard. If I spent CAD $1000 in Canada yesterday using it, it would have cost me AUD $1,014.71.

But if I spent CAD $1000 in Canada yesterday using a Wise card, it would have cost me AUD $1008.90, including Wise’s fees.

So, I’d save $5.80 - or 0.6% - in fees by using a Wise card instead of my no-fee Mastercard?

IKEA Matter devices - fixing their availability

I have a Google TV Streamer as my Thread-Matter bridge; and over twenty IKEA Matter devices in and around the house.

What I've noticed is that every single IKEA device becomes unavailable after rebooting Home Assistant (maybe you've installed a new HACS integration, or you've run an update). This is quite frustrating. But I think I have the fix.

You might notice that your Tapo plugs work just fine, but every IKEA device doesn't. IKEA devices use Thread; your Tapo devices don't. So that helps narrow it down, probably.

For me, the fix is relatively simple. Pull the power from the Google TV Streamer. Repeat the phrase "buggy Google code" three times, and then plug it back in again.

Once your Google TV Streamer reboots, you'll notice that every single IKEA device magically reconnects without any hassle.

From my point of view, the issue isn't with IKEA's devices at all; it's something to do with the Google TV Streamer (which came out, like Apple's TV 4K, before Thread devices were as easy to obtain as they are now).

Hope this helps someone somewhere.
