Perfect, got it working after a couple tries with your instructions. Thanks a lot!

The ZL1100 uploads data via its micro usb port (which also powers the unit) with an inbuilt CH340G usb-serial converter. One of the unfortunate features of the load is that it updates at a ridiculously high rate. It would be handy if a software could limit the log writes to one sample per second for example.

87

Should work, I bought this Ebay

88

Perfect. I will implement a sampling rate of 1second (or variable in settings, Not finished)

89

Zl 1100 should work if it has a com Port?

90

Its output is a bit different from the meters, but I’ll send you a sample tonight.

Here’s what the ZL1100 outputs in one second.

Thx, on monday I will update the app.

Nice weekend, mcpat

93

Who knows which device the golden one in the top left corner is?
And where is it available to buy?

Recently i found out about the round shaped device in the lower right corner, It’s the POWER-Z wireless charging receiver board (BG001):

94

Much appreciated, thanks!

96

I found YZXStudi products on eBay from >14 different sellers.
About which seller are you talking?

97

Is there some table that lists all the options and which each product has? Hard to keep track of, especially in english.

98

Thank you for your data. Need one more day, but it already works here for the zl1100, but chart need one day for developing…

99

Yes, Franky Tong helped me translate!

Also check out the feature list:

Ah, thank you thank you thank you!

I do believe the second link is broken though. Looks like the 1276 vs 1275 is a lesser model except for amp capacity

101

I can’t seem to find the power banks anywhere. Does YzxStudio still make them?

103

I guess that means no, the YzxStudio power banks are no longer available. Unless someone has a link to one

105

Hello there,

Updated the app:
should work with the ZL1100 load?
sample rate can be defined in settings, also path and logformat

But chart is not finished yet, therefore I removed the icon until finishing this function.

Download here

Regards
Patrick

106

Nice! I’ll give it a go tomorrow when I get back home from the Netherlands.

107

Please download again, I fixed a small bug… Forget the chart icon, it displays something, but it is not working.

108

You’re welcome :slight_smile:

I updated the second link again, no idea why it doesn’t work. Checked all permissions at google sheets, everything the same as the file in the first link.
But you’ll find the information here too:

I got the last one from Franky, but sad to hear this great powerbank isn’t available anymore.
