Hello,  
i’m currently wrighting on my Bachelor-thesis and Mender is part of it. Therefore i would like to know if it is possible to deploy an Update Module as Update from hosted-Mender to a Client as application update. Or do i need to send a whole Image-Update.  
If it is possible to update it as application update, do i need to write my own Update-Module which does this or is there a in-built solution for this case?  
I didn’t find anything in the documentation which clearly gives an answer to this question.

Kind Regards  
Florian

Hi Florian,

if I understand correct you can use the single-file update module to put your custom update module on a device ([Single File](https://hub.mender.io/t/single-file/486)). But in case of an image update the file will be lost and needs a re-deployment.

Cheers  
Ruben

Hi @fbaer,

actually I needed a very simliar functionality just recently. You can find the source [here](https://github.com/TheYoctoJester/tensorflow-lite-mender-demo/tree/main/mender/module), but as @ruben already pointed out: it will be gone after a full rootfs update.

Thanks to both of you. My next question would be regarding the pricing.  
Let’s say i got 1.000 - 1.500 Devices want Enterprise plan with Configure, Troubleshoot and Monitor Add-on what would the price be? Don’t need to be precisley a round about value would be more then enought.

Kind Regards
