New WiFi provider

[Jomaudeclark]

I have switched WiFi provider so I’ve lost connection to my solar panels. How can I delete my FoxCloud account and re set it up with new WiFi. It keeps reconnecting to my existing account with the old WiFi. I know I’ve got to scan the QR code on the WiFi stick in the solar batteries in the attic at some stage. How do I get to that stage?

There should be a wifi network showing with a name in the form `W-....` - for instance 'W-AAA1AAA'. Connect to that network (default password is 'mtmt2020'). You will get a warning saying the network has no internet - choose to connect anyway.

Once connect, go to 192.168.1.1 in your web browser. You can then change the WiFi details the datalogger will connect to on that page.

Do I just need to enter correct WiFi from drop down and password? The Mac details are different to the ones on the back of the router. It’s said it’s saved once but the app still says off line. Tried it again and now the blue circle is just going round and round in the screen......

OMG! It’s working!! Thank you SOOOOOO much.

No problem - glad you got it sorted

I have just had the same situation—switched to fibre finally with new router. Searched for a solution to re-establish wifi connection and nearly gave up as nothing seemed to work. Searched this site ,saw this post and solution—job done. So many thanks rmhumphries. PeteNZ

Alternatively change the new router networkname and password to the same as the old router. That way you don't need to change all your devices!

Still having problems. I log into the datalogger but can only get to 192.168.1.1 by connecting to my Wifi instead.
Is the password asked for there the datalogger password mtmt2020 or the Wifi password ?
Doesn't seem to like either.

Update - had an IP engineer on the phone to set up phoneline. Apparently 192.168.1.1 needs the admin password not the WiFi one.

As long as the screen looks like the below guide (from step3), it’s the datalogger password - but you have to connect to the dataloggers ssid itself first not via your wifi.

Wow thanks - at first got " cannot connect " but then it did ! and it even looked like the picture

Now got one of the inverters showing one more to do.

Excellent help rmhumphries, thank you. I had the same issue which thanks to you I have now solved. Quite proud of myself.

The only issue I had was that my iPad kept reconnecting to my home WiFi router which slowed things up a bit. If the ‘connecting’ message in the stripey bar persists, check that your device is still connected to the W…………… one.

Hi I have recently got a new BT router. I have tried the above steps to reconnect my solar set however when I get to the box my new wifi isn't listed in the drop down. Lots of neighbours wifis are there and my new wifi appears on my phone and on my laptop. Any advice please of what I need to do?

I tried renaming back to old one however it didn't work and also when I tried connecting still didn't get the renamed old wifi ssid in the drop down.

Please help if you can

So a couple of things, firstly is the range of the new router as good as the old one - i've heard the BT routers range is lower than some, but I can't confirm that myself. If you stand next to the inverter with your phone is the signal strength still good ?.

Secondly most modern routers transmit on 2.4Ghz and 5Ghz - the datalogger on the inverter only works on 2.4Ghz, so you need to be sure that your router has the 2.5Ghz band enabled.

Just in way of an example for the way i've done this - I have a wifi extender (one of these https://www.amazon.co.uk/gp/product/B08V5KZCXV) - I have it plugged in approx half way between the main router and the inverters location and linked it to the main router. I've then given the extenders wifi name a unique name (like 'myinverter') and disabled the 5Ghz band. That means everything in the house will use the normal router, I then link the inverters datalogger to the 'myinverter' wifi name and as it is only 2.4Ghz there will never be a problem with it.

Hi
I've had the same issue after a IP change, but when I get to the details page all the fields are blank and there's no option for my house WiFi, it just says "nothing".
Can anyone help with how to populate the details?

Thanks

That suggests that the new router might not have the range the previous one did.

You can try a reset on the datalogger to see if that improves things, it's fiddly to do it as you have to unscrew the collar at the top of the datalogger and then pull downwards, leave it 30 seconds and then plug it in and tighten the collar up. If you can't get access to collar the other way to do it is a full shutdown, restart of the inverter - there's a video guide here that explains that viewtopic.php?t=5

If that doesn't resolve it, you'll need to get a wifi range extender to increase your range, I use this one https://www.amazon.co.uk/gp/product/B08V5KZCXV which is very reliable, I disabled the 5 Ghz band, named it uniquely for my inverter and it's never let me down.
