I hope someone can help me out with this. I've spent all afternoon calibrating my ispindel but when I try to click the formel update in excel I get a visual basic 400 error. I have macros and visual basic enabled. Can somebody please do the calculation for me.
Thanks

I managed to get my calibration equation now. I was originally using excel 2007 and getting an error 400. When I run the script in excel 2016 it works fine without errors.

Does anyone have a simple parts list for building 1 of these? Or links to the parts on AliExpress? Cheers

Has anyone any tips for getting an Ispindel to use a wifi extender?

My brew fridge is out in the shed, too far away for the weak wifi from the Ispindel to get back to my hub. So I bought a wifi extender, to sit on top of the fridge.

The Ispindel will do what it is supposed to when connected to my hub, but does nothing when I move it to the extender. The blue light flashes as if it is working, but no data gets to Ubidots.

Updated the extender firmware.

My phone and laptop will connect to the extender and can access the internet.

It's difficult to see what's happening when it only connects for a fraction of a second then goes offline.

They work fine via my tp link power line adapters.

Try those?

Is the SSID and password the same?

But I've bought the extender now! No, it's a different SSID, with _EXT suffixed on. My phone and laptop can connect to it OK, but the Ispindel won't.

Make the SSID/password the same.

Makes no sense having them different even if it doesn’t resolve the issue.

The problem with that is that at the moment, I'm testing it, and I'm indoors, so the main hub is also accessible to the iSpindel. It will just connect to that because the SSID will match that. It works fine connecting to the hub in the house. But that will be no good when its out in the shed, in the garden. I want it to use the extender, now, and be sure it's using the extender, so I know it will work before I use it for real, in the shed.

Right, several issues:
1/ It seems you have to reserve an IP address for the Ispindel on the main hub. Perhaps there isn't time for a dynamic DHCP request to to get from the extender to the hub and back again, in the brief time the Ispindel is on line. When dynamic, the IP reservation just didn't look right. Reserved, it looks as it should.
2/ That got it working but only intermittently, a few readings logged then it would disppear. Solution: don't put the Ispindel near a LED desk lamp.
3/ That got it working much better, but still intermittently disappearing. Solution: upgrade Ispindel firmware. It now logs data reliably but it is really difficult to get into the WAP mode to configure it. It takes 10 or more resets.

Now calibrating it...

So, is the calibration graph supposed to look like the example at https://github.com/universam1/iSpindel/ ... tion_en.md?

My data points are scattered all over. There isn't a one that is anywhere near the formula line it is proposing.

I followed the instructions, kept the solution at 20C. Took 5 readings for each point and averaged them.

I noticed the Ispindel doesn't settle 'straight', the drawer is at an angle in two planes. Would that affect it?

You know, I'm hankering after hydometer again - it just works.
