Emteria Web Portal Pages Freeze

Receptor333 — Tue, 19 May 2026 13:25:20 +0000

I can log into the web portal and access the dashboard, but when I click through to devices or really any link on that page, my browser freezes. I've tried Firefox/Chrome(incognito)/IE and multiple computers. It has also persisted over a couple of days now for me. Does anyone else have this issue?

Can't activate a previously activated device in a new account...

George_Jackson — Sat, 14 Mar 2026 15:08:07 +0000

Hello!
I have this problem where I want to activate my device, but Emteria's system tells me that it already was activated with another licence key. A licence key from an account that I can't access anymore. At this point, I don't even remember the credentials that I used for that account. So, i tried to recover the password using my current email accounts, but all of them returned a message that said that the account couldn't be recovered because it doesn't exist. Or something like that. So, I don't know how to recover the account that I used that time to register my device.

I assume that I am gonna be told something like "there's nothing we can do about that". But i would still want to ask, can I get this device to be activated in my new account?. Because I don't think that it is actually "impossible".

By the way, back when I supposedly activated that device, the system worked so badly that I got disappointed and decided to just send my account to oblivion, probably without even deleting my account.
As far as I can remember, I wasn't even able to connect to the internet because the system was buggy AF. So, I wonder how I was even able to activate it that time.

Please, say you can actually help me with this seriously annoying issue.

I only want to use my Raspberry Pi as a regular android device because android images for the RPi are practically non existent, and now that Emteria's system seems to be more usable and stable than it was like four years ago or so, I actually feel like I would actually be able to use it and enjoy it now.

I hope someone can help me with this, even when the info I found about my problem says my problem "can't" be solved.

We just created a new account activated the three starter licenses and then tried to activate a raspberry pi flashed with your latest software and when we get to the point where it asks for an activation code or a login I type my login and it says request failed

Remote App Launch Not Working for EmteriaOS 15.4.0 (Raspberry Pi 5)

legolas — Mon, 20 Oct 2025 10:27:06 +0000

I’m encountering an issue with remote application control on a device running EmteriaOS 15.4.0 (Raspberry Pi 5).
While the remote stop functionality works correctly from the MDM platform, the remote start (launch) command does not seem to take effect — the app simply doesn’t open on the device.

Is this a known issue with this version or device?
Are there any specific permissions, settings, or requirements I might be missing for the remote start command to work?

Thanks in advance for any guidance!

Free plan voucher code not working

gpouger — Wed, 23 Oct 2024 09:37:03 +0000

Hi,
I registered for a free plan, received the email with a voucher code but it's not working.
I made sure that there are no leading or trailing spaces.
Also I don't have a bell on my dashboard.

Note that when I first registered my account got deleted for some unknown reason - I registered again with the same email and I received the same voucher code as with my first registration attempt.

Can you help?

when entering a license "error contacting server request was invalid"

MLevin — Tue, 04 Apr 2023 19:24:01 +0000

A RPi3B+ that has worked for years starting showing an invalid license. I tried both the license number and email to activate the device again. Both failed with the following error.

"error contacting server request was invalid"

I pulled the flash card and reinstalled the OS from scratch and during the setup when promoted to enter my license email and password I get the same error.

What can I do to get past this licensing issue? There doesn't seem to be any support option even for paying customers.

No Voucher Code and No Bell Icon

simpz — Wed, 27 Mar 2024 14:51:48 +0000

Moving this into it's own thread. I have probably had an Emteria account for so long that I've never had a voucher code email.
And I don't see the bell icon under the Redeem voucher on my account. Can you enable this for me?

Hide kiosk settings button via command

Jeroen — Wed, 29 May 2024 11:39:13 +0000

Hi,
I was wondering if it's possible to hide the kiosk settings button via a command or preference. I'm trying to automate this step but I can't seem to find the correct way to do this without using the toggle.

Is there an MDM command to do this?

Bug when moving licenses between groups

SanderK — Thu, 02 May 2024 12:20:47 +0000

There is a bug (well I assume it is a bug) when moving licenses between groups. If you apply a search filter to the device overview, you can only move licenses to groups that appear in the search filter. This makes it impossible to quickly look up a device by serial number and then move it, since only the group the device is already in is listed as a possible destination.

Raspberry Pi 3B+ Image not available in the RPI Imager

The title says it all. Are the RPI 3s not being supported any longer? I can only see the RPI 4 images available.

Error contacting server. Request was invalid

Brown375 — Wed, 27 Dec 2023 19:26:55 +0000

When trying to activate my evaluation version, it will not let me sign in. It tells me "Error contacting server. Request was invalid. If i use the activation code method, it tells me "No suitable code for this device". I cannot figure out for the life of me how to get this Pi3B+ activated.

Device OFFLINE even if activated

Ringo982 — Fri, 03 Nov 2023 08:24:24 +0000

Hello!
I have correctly activated my raspberry pi3 with one of my codes. The watermark is disappeared and the license manager indicates the device as activated. I see on the dashboard on the website the record, the last sync time is correct, but the device is set as OFFLINE.
Tried reboot, cleared license data and re-joined, but nothing changed.... any idea?
Thank you

Need to remove the pop-up window that reads evaluation version

Cardinal — Fri, 11 Aug 2023 21:18:14 +0000

We have the free plan with 3 licenses. We have only used one of the licenses to develop the Pi into an IoT kiosk. Now we want to test it out in the public and generate feedback on the interface. Is there a way to remove the white box that shows that it is an evaluation version? We want to use our two remaining licenses on an A/B test to determine user preferences. To do so, the system will need to remain on for days at a time. Thank you.

Move device from 'basic' to 'starter' plan

Iain — Sun, 25 Sep 2022 12:06:44 +0000

Hi,

I've got a device within an auto-generated group that was created when I purchased a single-device basic plan that has expired. Can I move that device to a group within the 'starter' plan?

I tried doing it through the UI Portal and it looks like I can't do it there because I would exceed the number of devices in the 'starter' plan. I've tried entering a different key in the device, but it looks like this can't be changed and is locked to the device.

Any ideas?

Thanks

Suddenly license not working

Cyberetti — Tue, 09 May 2023 19:30:44 +0000

I have had several licensed raspberry’s working for years and suddenly my RPi4 says I am not licensed anymore?

Is there a way to buy licenses in 25/50 increments? Paying for 100 licenses when I only visualizing to use 25, 50 top; is not cost effective. No way tu buy licenses as needed? email support is non existent. How I I'll be willing to pay thousand of dollars while I can even get tech support.

Provisioning emteria settings and kiosk

bart — Wed, 03 Nov 2021 10:28:14 +0000

Hello,

I'm trying to setup provisioning of the preferences of emteria Kiosk and emteria Settings. In the emteria knowledge base I found the way to enable kiosk mode (prefs_kiosk_enabled_key) and the allowed apps (prefs_allowed_apps), but I didn't find the preferences to hide the back and home buttons in kiosk mode and the preferences for "Keep awake" and "Screen orientation lock" in Emteria Settings.

Kind regards,
Bart

Upgrade of Raspberry Pi 3 to 4b. Will I need to purchase a new license?

leneil71 — Sat, 18 Sep 2021 23:39:22 +0000

I am planning to upgrade my current Raspberry Pi 3 to 4b. Will I need to purchase a new license or can I reuse my existing license by deactivating it on the old device and reactivating it on the new device?

Evaluate Provisioning and Device Management

alexpreston — Sun, 25 Jul 2021 15:52:16 +0000

Is it possible to freely evaluate provisioning and remote management features or is a license required to access those features?

I have the evaluation version installed on a RPi4 but can’t get it to show up in the web portal.

Sharing Access to License Groups on the Web Portal

JonathanD — Fri, 02 Jul 2021 14:51:35 +0000

I am trying to add a second manager to my license group, I added via email (emteria username) and can see that person in my list. However when he logs in there is not obvious association with the license group that I create on my account. How do I give my colleague access please and where should he be looking to see the Licenses that we will share the administration of?

Subscription Plans

FJEDEV — Mon, 17 May 2021 10:13:31 +0000

I have a Basic Plan subscription for a couple of devices. I wanted to know what happens if I were to cancel the plan after one year. Will the device continue to work as is and just not receive any updates, or will the device revert to an evaluation version of the OS and receive notification messages ?

Emteria MDM

timothyle — Mon, 22 Mar 2021 04:06:21 +0000

I am unable to use the MDM function of the premium subscription as the device never shows up as online. It appears to intermittently contact the server, as the "Last online" time does update from time to time. However, none of the software version information or system information appears under the System, Hardware, Networks, or USB tabs. None of the installed applications on the device show up under the Apps tab.

I am not sure if this could be a firewall issue, but I have checked all of the firewall logs and it does not appear anything is blocked.

Wondering if someone else uses the MDM and has had a similar experience.

License change

mikeyg — Wed, 31 Mar 2021 18:16:15 +0000

I currently have two licenses. One is currently listed to a device, and one is still waiting for a device to register to.
Well, my house burned down last year and it has taken this long to handle all of the other stuff and now It's time for me to start rebuilding my lab. Is there any to associate my currently used device to another one? The first device has melted, so I will never recover that piece of hardware.

How to remove license and move to new device

boomhaueruk — Tue, 30 Mar 2021 09:57:12 +0000

Hi,
Quick question - I installed Emteria to a Raspberry Pi, which pretty swiftly died.
Haven't thought about it for a while, now just got a new PI, wanted to install Emteria.

I've read this;
https://emteria.com/kb/introduction-to-licenses

Am I reading this right "After successful activation of your device your license can not be disconnected from this activated device and can not be transferred to another device after the activation."

That's it? I bought a license and can't move it if the Raspberry Pi dies? Or under any circumstances?

Please tell me I'm reading that wrong!

Where to purchase the license?

fishred008 — Sat, 24 Aug 2019 22:03:48 +0000

I know it is stupid but I can not find a link to make the purchase once i logged into my account in Emteria.
