Tigo optimizers still need the custom sensor

[popoviciri]

I use Tigo optimizers logged by my Sunny Tripower via a Tigo Access Point (TAP). The following custom sensors are logging Power and Temperature of each optimizer (only first two shown as example):

- platform: sma
  custom:
    power_tigo_1:
      key: '6100_40652A00'
      unit: W
      factor: 1
      path: '"1"[0].val'
    power_tigo_2:
      key: '6100_40652A00'
      unit: W
      factor: 1
      path: '"1"[1].val'
    temperature_tigo_1:
      key: '6100_40652B00'
      unit: °C
      factor: 10
      path: '"1"[0].val'
    temperature_tigo_2:
      key: '6100_40652B00'
      unit: °C
      factor: 10
      path: '"1"[1].val'

To add this in the main integration may be complicated since requires additional inputs regarding the number of panels monitored, if any. Please consider keeping the yaml custom sensor alongside the GUI integration, unless this is a hard requirement from the Homeassistant folks. Will keep using a custom integration for now. Thanks for your work! Cheers!

Hi @popoviciri

I am currently working on new logic to easily provide different sensors based on the device type and connected extra's Do you know if there is a key to determine if (and how many) are connected?

Would you be able to provide an export of requests to getAllOnlValues.json and getAllParamValues.json? That would help locating the correct keys to query and what data to expect.

Login to the webinterface of your device and go to the "Home" page Open developer tools, go to network tab. Click clear in the top left and make sure recording is on.

While keeping the recording running: Go to page "Instantaneous values" (a request to getAllOnlValues.json should appear) Go to page "Device parameters" (a request to getAllParamValues.json should appear)

Save these requests as a HAR file and share that file.

This document might help: https://support.zendesk.com/hc/en-us/articles/204410413-Generating-a-HAR-file-for-troubleshooting

After a quick search I found these:

            DcMs_PanLevMdul_Vol: {
                obj: "6100",
                lri: "40652800"
            },
            DcMs_PanLevMdul_Amp: {
                obj: "6100",
                lri: "40652900"
            },
            DcMs_PanLevMdul_W: {
                obj: "6100",
                lri: "40652A00"
            },
            DcMs_PanLevMdul_Tmp: {
                obj: "6100",
                lri: "40652B00"
            },
            DcMs_PanLevMdul_SigPwr: {
                obj: "6100",
                lri: "00652C00"
            },
            Operation_PanLevMdul_Health: {
                obj: "6180",
                lri: "08652400"
            },

            DcCfg_PanLevMdul_Lbl: {
                obj: "6800",
                lri: "10852500"
            },
            DcCfg_PanLevMdul_SerNum: {
                obj: "6800",
                lri: "10852600"
            },
            DcCfg_PanLevMdul_Model: {
                obj: "6800",
                lri: "08852800"
            },
            DcCfg_PanLevMdul_SwRev: {
                obj: "6800",
                lri: "10853300"
            },

Maybe the 6800_10852600 could be used. If multiple serials are provided I could count them and add sensors as needed.

Could you try to run the example.py from my dev branch against your inverter to see if it returns the optimizers now? https://github.com/rklomp/pysma/tree/dev

[popoviciri]

WOW. I did not expect this when I asked for the custom sensor back :). Awesome work! "The sun is getting low" :wink: and there is no power generated at the moment but inverter is still up. Here's the output from your example.py:

I can try tomorrow again, when the sun will hopefully shine again, but even with this data I can say it works! Temperature has to be divided by 10 (I do not know why SMA did that. I apply a factor 10 in my custom sensors as well). I do not have a meter so the first lines are throwing the error. You were right to use 6800_10852600. There are other options as well, but serial numbers seems solid! I am not comfortable sharing entire HAR files and editing those is a pain, but I got the json response extracts from firefox: dumps.zip The attached files mirrors this: You probably don't need them anymore but maybe you find other useful stuff in there. Thank you very much once again for your work! Cheers dumps.zip

[rklomp]

Thanks! Looking good! I think the serial is not really needed as a sensor right?

Would DcMs_PanLevMdul_SigPwr and Operation_PanLevMdul_Health be of any use as a sensor? Any other values you would like to read?

I see the DcCfg_PanLevMdul_Lbl would give me the name of the optimizer. I could also name the sensors optimizer_power_AA1, optimizer_power_AA2, etc. What would your prefer?

[popoviciri]

I realize you do not actually have access to an inverter with optimizer, so here is how that looks like: Personally I only use the power and temperature, and named each one very originally tigo1, tigo2 and so on: These two are more than sufficient to identify a defective panel. Or optimizer :).

Sensor naming as optimizer_power_AA1 seems a good idea for installation with multiple strings. But Signal Strength and Status/Health are in my opinion pointless, because the zigbee network is always dropping packets, so those sensors will add no value. Same goes for serial numbers.

Some might find relevant Voltage DcMs_PanLevMdul_Vol and Current DcMs_PanLevMdul_Amp besides Power DcMs_PanLevMdul_W.

Thank you once again for this! Cheers

[rklomp]

I just fixed the optimizer_temp. It was querying the wrong key (same key as voltage). I should now return correct values. (9e5646417144be6b6b734c6223a5b48abfee3081)

@popoviciri

I am creating a file with test data for testing the code. Would you be able to share the response of your inverter for POST requests to /dyn/getAllOnlValues.json and /dyn/getAllParamValues.json?

You can get those via the developer console of your browser when you visit the Instantaneous values and Device parameters pages. The getAllParamValues.json includes WiFi network names, MAC address and IP addresses if you want you can change these to something else. But please keep it as valid data ;)

If you need any help let me know. Thanks in advance!

[popoviciri]

Hi @rklomp, I had these exported one year ago when you first updated this integration: dumps.zip. The optimizer bit reflects this screenshot: If you need something else, let me know. Cheers!

[rklomp]

Thanks! I did not spot it while scrolling trough this issue. Added your data as a test case: https://github.com/kellerza/pysma/pull/109/commits/e71b25e6b5a5e7205aae47c50ad62ded87e5c3b7
