Hi I recently asked the developers of the Plejd app to add energy capability for their devices. All the Plejd devices have advanced settings “Power usage when on” / “Power usage when off” which is great for devices that don’t measure themselves but the load is so static that the power can be estimated instead. This way I can get power usage from these devices. But since they do not have energy capability (kwh) the devices don’t show in the new energy tab of Homey. I think this would be easily done, but the developers of the Plejd app say this is up to Homey, they cannot do this. So, help Athom Homey developers, can you add this? ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/0/9/091704ddca98847fc500fb8dc2616a22a1c017c9.jpeg) ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/e/e/eea597424ed09aa69d3a16dc398cb105a6d172a6.jpeg) ---

> [@arune](#): > > All the Plejd devices have advanced settings “Power usage when on” / “Power usage when off” which is great for devices that don’t measure themselves Exactly, Plejd can’t make up energy data from that. To actually record the real power + energy, you’ll need to add a power measuring device to those devices, like measuring power plugs. When a machine, like, CTR-01, doesn’t provide for electricity values, the Plejd app developers can’t add those to the app. Do those devices show energy values in their respective phone apps? ---

Ah, I’ve used it before, but let me get you correct, you mean to create a “virtual device” for each of my devices with manual power settings that accumulate the energy (power over time)? I guess that is possible but I have over 20 devices which will be cluttered and difficult to maintain. I mean, Athom/@Emile could implement this right? If a device have a capability of power (which I believe is automatically created for these type of devices) it should also be able to calculate the energy. ---

This is the Homey app documentation of what I’m talking about: > **[Energy | Homey Apps SDK](https://apps.developer.homey.app/the-basics/devices/energy#approximated-power-usage)** > > By defining the energy usage (or generation) of the devices your app supports users can generate detailed reports of their energy consumption. > In cases where devices do not support `measure_power` real-time energy usage in Watts, there are a few options to approximate the device’s energy consumption. Homey can calculate the energy usage based on the `onoff` and `dim` capabilities when there is no `measure_power` capability available. Homey will provide the user with settings to configure the energy consumption when the device is turned on, turned off, or (when a device can’t be turned on or off) its constant energy consumption. Using these settings Homey approximates the energy usage by calculating the total on-time, optionally taking into account the brightness level. This is not fully true however, a bit confusing, it does not calculate the energy (that is what I’m asking for), it calculates the power usage. > **[Energy | Homey Apps SDK](https://apps.developer.homey.app/the-basics/devices/energy#power-usage-when-off)** > > By defining the energy usage (or generation) of the devices your app supports users can generate detailed reports of their energy consumption. > This setting is provided to devices that do _not_ have the `measure_power` capability and _do_ have the `onoff` capability.

Yes, I agree, this would be very welcome! Here’s why for me: When the Innr SP-120 were discontinued I ordered a bunch of SP-220’s for which I found out to late they don’t support power measurements so they don’t show in the Energy dashboard. What I do is, for devices which have a static power usage, I first connect them to an SP-120 to determine the usage. After that, I replace them with an SP-220 in which I enter the _Power usage when on_ with the determined value. It don’t see why Athom can’t make it so my Homey calculates the energie usage based upon the entered value and the time the device is switched on and write that to a capability, I really don’t want to add an additional app and additional device for that. ---

I too don’t understand why this is not represented in the Energy tab. What is the point of setting the power consumption of a device if I can’t use this info anywhere ? I hope it will be implemented soon. ---

Yes, those devices (which have an estimated power usage based on the on/off values you set) are now also included in the overview of Top Consumers. > [@Lights in energy consumption tab](https://community.homey.app/t/lights-in-energy-consumption-tab/156796/10): > > The Top Consumers section in the Energy tab now also includes devices with an estimated energy consumption +1. ---

I’m doubtful. It says approximated **energy** devices, not power devices. **🤷** I got this version installed during the night but my approximated power devices don’t show up: ![1000030234](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/4/f/4feba44d4d452349b8645563a1112c85236bddeb.jpeg) ---

In my case I had to wait several hours before the devices showed a kWh (energy) value, though the device was listed in the Top Consumers overview with no value initially. Those devices do let you set the power usage when off and when on? And the Exclude from Energy toggle is turned off? ---

They do, see screen below. But there is no “exclude from energy”. ![1000030236](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/7/2/72ea92e86aea39730e53052826a8a9f97a3636e3.jpeg) ---

That’s strange indeed. Suggest you reach out to Athom (via [Support | Homey](https://homey.app/support/)) so that they can check why those devices don’t appear. ---

Works today! I guess it took a while after adding the “power while on/off” info.
