    Matthias Oliver Many reasons have been provided ranging from network security to potential data losses with the cloud and the need to have internet at the site and just having slow data is useless. Also those who want to implement local data can save money compared to the premium package. However the most important one is the ability to create home automation and energy consumption control based on live data. For example I want to heat my house with electricity based heaters. I am planning on turning them on and off when there is enough PV power available to limit the energy import from the grid to minimum. Such approach is super helpful in EU where the Nordpool prices sometimes are super low or even negative and exporting energy would actually cost money. The faster the data is - the more accurately can devices be controlled. When a cloud goes over the array the consumers can turn off and start up again when there is enough PV output. This approach can be taken for any number of things. Heating hot water, cooling the house with AC, charging an EV or battery.

    Solutions like this can help achieve lower grid import and maximal self consumptions.

    So again, what is your application? You want local data, but why? That's what makes this sound fishy. 

     
     
    Stop asking, "what is your application", and search in this thread for use case. As I've said, I provided many use cases. If you are incapable of comprehension, then you should not feel obliged to ask questions that have already been answered.

    Nice dodge. I wave a dismissive hand at you.

    You skipped to the bottom to hit reply while ignoring all the relevant information that answers your question. It's you who have dodged.

    No, no, Koti provided something relevant. Just now. You did not. I suspect you will go cry to reddit now. lol

    Koti Vello send those suggestions in. It is apparent nothing will be solved here.

    Relax, Matthias, he has made the same points in this thread as I just did. Both me and him are asking valid questions and features to be provided. If these are features that you do not need or are interested in then you probably can not contribute anything useful here.

    Incorrect once again. You really are useless and incapable.

    It seems this thread has devolved from its intended purpose. If you have any further comments for Tigo Portal enhancements, please click here to submit them to the software team directly. EI PORTAL FEEDBACK

    Just wondered if there was any updates on this. I read elsewhere that some users managed to get access to the CCA web interface to pull data but Tigo then blocked this by adding an IP restriction. Can Tigo confirm please if this is true? If so, why limit this? Just allow the user to change the .htaccess password login details and we can do the rest then (wget etc) to pull live usage

    Yes, there is an update. Tigo went out of their way to further revoke access in firmware 3.7.7, replacing the `/cgi-bin/shell` script which had previously enabled SSH with one which spins a random amount of time and otherwise does nothing. Tigo could have removed it entirely, but instead they replaced it with a useless script to intentionally misdirect anyone who would dare to access their own device.

    Tigo: I don't want to tinker with my CCA's internals, I just want live telemetry directly from the Tigo hardware I bought. Add a `/cgi-bin/metrics` script to dump live telemetry as Prometheus metrics – or indeed any similar mechanism – and I would be satisfied. But instead, Tigo slipped this kind of breaking change into an update I couldn't refuse, indicating that Tigo views its customers as adversaries.

    This is a story that I am suddenly eager to share. It is a bad look for Tigo, it is entirely avoidable, and based on Tigo's embedded Linux security history, it will ultimately fail to keep customers out.

    The irony here is I have told more people to get solar edge over Tigo now than I have lost count of. It's not that the Tigo product itself isn't good, it's the fact that the app and website suck (seriously the most unreliable piece of rubbish ever seen coded) and for.people like ourselves who would like to see the data in an app that doesn't suck and use it for home automation are blocked deliberately for no valid reason. It would be so easy to make the data from each panel available locally but they either don't want to or the more likely scenario is they just aren't good enough at coding/product development to know how.

    Even more ironic: I already found another way to enable SSH in 3.7.7, because Tigo's security is indeed terrible.

    ~ # cat /mnt/ffs/mgmtu/res/version 
    export TIGO_VERSION=0.0
    export TIGO_BUILD=3.7.7-ct

    The date on this build is June 20, so in total this change to lock users out of their own devices lasted four and a half days.

    In my opinion Tigo should be worried about Cloud Connect security, but of their own API, not of the devices they sell. Every CCA ships from Tigo with a system ID stamped into its memory, but they all use the same hardcoded credentials to access Tigo's cloud APIs – meaning any CCA can impersonate any other. People on other forums have reported changing their system IDs and retrieving other users' data, and I can see from the 3.7.7 upgrade package that Tigo hasn't taken any actions to fix this.
