I‘ve tried to update. It seems they have also change again something in the configuration because it reconfiguration with app was ok but was not working correct. I didn‘t see the configured buttons. Only for your information, I reloaded 2.0.1.
I have just updated one of my panels to V3 and it also doesn’t work. I see no errors when sending the config and even if I export the config from the app and import it via the Button+ web page it doesn’t work.
So I have messaged Ronald to get some help.

FYI: I have updated the Button Plus to 3.0beta6 and currently it is working. I will inform you if it is not running after a while
Good. I have been feeding back to Ronald and he has been fixing, so hopefully it should be all working.
Any news on the app in combination with the new v3 firmware, @Adrian_Rockall?
According to the latest newslette/blog Ronald sent out today, the new firmware is only days away.
Would it still be wise to wait a little before updating, or have thing been improved yet?
The app is working with version 3 beta 3. I haven’t tried the latest one yet though.
My buttons are working fine with v3 beta8

Great! Thanks for the response
Hi all. I’ve read through this whole thread, but couldn’t find my current error. I’m reinstalling my Button+ after a few months and a new Wifi network. Button+ connects with the network, but I can’t get it to add to Homey as a device; it gives an error message in red: ‘Error: Missing Parameter: device.data; Probeer opnieuw.’
Button+ is on fw2.0, Homey Pro, Button app v0.7.24
Few months ago this process was super smooth.. 
Firmware 3.0 stable is out.
Upgrade went without problems - but headings are now blue in the display and yellow on the buttons…
Here also:
Firmware 3.0 on button+ works here without a problem with Homey.

Firmware v3.0.1 (also tried v3.0.0) was no success here…
The text on some buttons is misaligned or even absent after sending the same configuration I used before on v2.0.1.
When re-installing v2.0.1 firmware again, everything is working as expected again…
Firmware 3.02 installed and it works. Headings on display still blue.
The Homey app doesn’t control the text colour, so all I can suggest is to open the device web page and check the Main Colour in the General settings section.
Thanks @Adrian_Rockall !

Since I upgraded my Button to v3, I can’t display any text string anymore.
For example the Homey variable contains “21 / 60% in 15u”, but the button displays only “21”. Any addition is being discarded. Setting the decimals to 0 does not change anything.
If the string only contains text, it works as expected. If the string starts with a letter, it also works. Except when the string starts with a symbol like + or - or a number, it only displays the number.
Edit: just tested by publishing directly to the Button, without the Homey app and the issue still persists. I’ll contact Button+ directly.
There is a new version Button +: version 3.03
I have installed it and it works.
Hello, I have a display configuration with two pages. This morning I accidentally pressed FW update and now the display shows the two pages kind of overlapping and the ‘display select buttons’ have no effect anymore. Tried reset, factory reset, PTP, FW downgrade to 2.0.1 but no result. The figure is from the ‘web interface’ that mimics the device, even there it is visible. Any idea how to solve this?
Can you check the configuration page to make sure it is still referencing two pages.
