[RELEASE] LogicMachine firmware 2025.12 - admin - 11.12.2025
LM 2025.12 release firmware is published.
Most notable changes from 2024.04:
- Old visualization is disabled for new installations (does not apply if upgrading from an older version or restoring a backup)
- New Visu beta app added
- Added support for new Visu cloud version
- Mosaic app removed
Old visualization and Mosaic can still be used with this firmware. No new features will be added to old visualization and Mosaic. Only critical bug fixes will be provided.
You can find your hardware model in the "Upgrade firmware" window:

RE: [RC3] LogicMachine firmware 2025.12 - _BG_ - 22.12.2025
Hi,
I already have a significant number of existing installations where LogicMachine is used as the main BMS platform,
with strong use of JavaScript and CSS.
Does this mean that in future firmware versions the old visualization will no longer be available at all?

If you do a factory reset to your LM old visu will be hidden but it is enough to load a backup which contains old visu then it will be back. There is also a way to enable old visu in fresh LM.
We are hoping that after some time everyone will switch to Visu but we will not hurry to remove old visu from LM. If customers will want it there we will keep it for as long as it is needed.

Hello, some of the our customers are reported that there is zerotier connection problem with this firmware. They downgraded to 2024 and it's solved.
RE: [RELEASE] LogicMachine firmware 2025.12 - admin - 05.01.2026
RC3 has been marked as stable release version.
@savaskorkmaz, normal LM firmware is not affected with ZeroTier issue.

I'm using an LM5 Lite (3 DIN units). I'm trying to update it but I'm still getting the "Cannot upgrade, firmware image file is invalid" error.
RE: [RELEASE] LogicMachine firmware 2025.12 - Daniel - 16.01.2026
What is your exact model? Check side label.
RE: [RELEASE] LogicMachine firmware 2025.12 - xxyzz - 24.02.2026
Hi,
I was just trying to comission a new LM and wanted to upgrade it to the latest firmware. But when I try to add the firmware file and signature file i get an error claiming that the signature is not valid.
The label on the side is: LM5Lp2
Thanks for your help.
RE: [RELEASE] LogicMachine firmware 2025.12 - Daniel - 24.02.2026
Try downloding the files again.

Goodmorning
same problem with same product. LM5lp2
RE: [RELEASE] LogicMachine firmware 2025.12 - admin - 30.03.2026
Try downloading both firmware and signature files again. Reboot LM before performing the upgrade. If this does not help then post a screenshot of "Upgrade firmware" in System config.

Hi.
I have an LM5p2-PMC. The device label shows:
LM5p2-PMC
LM5M3V30B24090197
In the upgrade window the device reports:
HW: LM5 Lite + Ext (i.MX6)
SW: 20240426
I am trying to upgrade to firmware 2025.12 using the row:
LM5 Lite + Ext (4 or 6 DIN units)
Files used:
lm5m3ex-20251204.img
lm5m3ex-20251204.sig
I have downloaded both files several times and rebooted before trying the upgrade, but I still get:
“Signature verification failed”
Can you confirm whether the 2025.12 signature file for LM5 Lite + Ext / LM5p2-PMC is correct, or if this device requires another upgrade path?
RE: [RELEASE] LogicMachine firmware 2025.12 - Daniel - 15.05.2026
Reboot LM and try again.

I have rebooted the LM countless times; still "Signature verification failed". Tried to downloaded the FW files several times + reboot of LM; still "Signature verification failed" . I have even tried the same procedure on a second LM; still get."Signature verification failed". Could there be something wrong with the signature file?
RE: [RELEASE] LogicMachine firmware 2025.12 - admin - 15.05.2026
Run this script once and post what you get in LM logs tab.
Code:
res = io.readproc('md5sum /etc/ssl/certs/* 2>&1')

Devices are new, just unboxed? If yes before upgrade set the correct time of the LM. I had the same problem on LM5Lp2 and I fixed in this way.
