I’ve received the Homey Dongle, installed it, and it works perfectly. However, I don’t see the value showing how many kWh I’ve used today. I only see the total kWh, import and export, and the low and high tariff values. Is anyone else experiencing this issue? ![IMG_4623](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/5/f/5f52d14529c17e509e4da1d225b584e0b36568fd.jpeg) ![IMG_4624](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/1/6/16c69295afbdff1bd01c80694998b10ab78b0212.jpeg) ---

UPDATE Tried again today. First attempt: same problem. My car charger cannot do load balancing so it switches off. Second attempt: connect external power supply. This seems to work! No error messages anymore. Let’s see if it stays behaving over the coming days… ---

I know it can be done with that, I use this too. But when I read @Dijker’s post above (12), it looks like he does have that value showing? ![IMG_4625](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/a/7/a725881838ab058d91a7328e9a458633b52605b2.jpeg) ---

> [@Rob\_G](#): > > Second attempt: connect external power supply. This seems to work! No error messages anymore. Let’s see if it stays behaving over the coming days… When using the passthrough the additional USB-C power must indeed be used for everything to function properly, especially if the Dongle attached to the passthrough doesn’t have its own power source. So if that wasn’t connected before that could explain the issue. ---

Do you have power on both the splitter and the dongle? Or only on the splitter? ---

Findings: - Energy dongle connected to a Landys + Gyr E360. → Red solid LED. As suggested by Doekse to power the energy dongle via USB. Dongle connected, updated firmware to version 12 and is receiving data. After the upgrade I tried without using USB power: dongle reconnected to WiFi once, otherwise it seems fine. - Reported current is wrong 0,06A is rounded to 1 Amps? - Negative current (solar power) is shown as positive current value. - Negative power is reported correctly. - Current is not corresponding to Voltage times current (?) somewhere around 340w load it is already showing 2Amps? (but is slights less than 1,5A). In screenshot of Doekse this is also showing. - Load percentage is based on rounded Amps value, so minimum (in my case) is 1/25 - Daily usage is not showing on tiles, but is available on Energy Tab. - Dutch is odd: “Stroomvermogen” should read as Vermogen. stroomvermogen is not a correct dutch word. - in dutch there is still “Energy” (instead of energie). There is still some work to do… ---

- It appears that the meter is detected as “US” landcode? - The RAW P1 meter data (below) is only reporting Full Amps, the value shown in Homey is the same as ID’s: 1-0:31.7.0 1-0:51.7.0 and 1-0:71.7.0.

> [@R\_V1](#): > > - Reported current is wrong 0,06A is rounded to 1 Amps? > - Negative current (solar power) is shown as positive current value. This is info from the P1 port from the DSMR standard: ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/3/8/386851b935bc6e77714580bc743d3e8a4b236b0e.png) also for L2 (1-0:51.7.0.255 ) and L3 (1-0:71.7.0.255 ) It is the current, in any direction. (UnSigned Interger) in A (Ampères) so correct display by the Homey Energy dongle and to change that you need to rewrite the DSMR specification. > [@R\_V1](#): > > Load percentage is based on rounded Amps value, so minimum (in my case) is 1/25 Correct, that is the current in or out your house. Just relative to the configured loadvalue ( fe 25 or 30 A conform your contract and Main fuses) > [@R\_V1](#): > > - Dutch is odd: “Stroomvermogen” should read as Vermogen. stroomvermogen is not a correct dutch word. > - in dutch there is still “Energy” (instead of energie). Also reported this, guess the external translators are not native Dutch, probably fixed in a FW update soon. ---

I noticed that as well; That is what I actually meant with the last post. The energy dongle is reporting the telegram data correctly. It is a design choice to follow the dsmr specification. Personally I think a rounded value from the specification is odd, and would have expected that the current is calculated. ---

My car isn’t charging bur the animation shows its charging all the time. I think because the charging point is using 1 watt while idle. I think you only should see the animation when the point is active or maybe when more then x watt ---

I also get this message many times a day. I haven’t been able to detect where the notification is coming from. I did not make a flow yet with the dongle, so why do I get a notification? Did you make any progress? ---

Hi everyone 👋 I connected the **Homey Energy Dongle** to a **Landis+Gyr E450 smart meter** in the **Netz Burgenland** region (Austria). Although the P1 port is activated and the encryption key is correct, I receive the error: _“The Homey Energy Dongle could not connect to your smart meter.”_ The same meter works flawlessly with the **HomeWizard P1 Dongle** , which suggests that the E450 sends a **non-standard or modified P1 signal**. Can you confirm if the Homey Dongle only supports strict **DSMR 4/5 protocol** , and thus cannot read data from the E450 in this configuration? Is there a way to fix it? Thanks for your support 👍 ---

> [@R\_V1](#): > > It is a design choice to follow the dsmr specification. Nope imho the Dongle is an interface to get the reported data from the meter to Homey. If you want to know the current in more details you can calculate it from power and voltage. ---

Hi Christian, Well, when the Homewizard P1 works with your meter, it should be possible to make the Homey P1 dongle compatible I expect. ~~Unfortunately Athom’s information isn’t complete, they seem to think the Austrian Landis+Gyr E450 is an unsupported M-BUS version for all of Austria? P1 versions seem to exist as well?~~ > ![1000046592](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/d/2/d2c50e31f16b660dfa688b87b24b598a4f958250.jpeg) > ![1000046594](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/a/8/a8e1f923d137c9b38f1b7c5a73f5f81756f7b34e.jpeg) Source: [https://support.homey.app/hc/en-us/articles/17233328965916-Compatibility-of-the-Homey-Energy-Dongle](https://support.homey.app/hc/en-us/articles/17233328965916-Compatibility-of-the-Homey-Energy-Dongle) [Previous page](https://community.homey.app/t/homey-energy-dongle-megathread/133816.md?page=6) [Next page](https://community.homey.app/t/homey-energy-dongle-megathread/133816.md?page=8)
