There are a couple of advantages: no single point of failure, much smaller in size (and neatly tucked away under each panel), shade or dirt on one panel does not affect electricity production of the remaining panels.
12 months ago I paid about 10,000 AUD which already includes about 4,000 AUD government subsidies, i.e. the outright price would have been 14,000 AUD which is about 10,000 EUR.
Hi @exxamalte - I also have an Envoy, but the /production.json endpoint isnât available. Any idea if I have hardware thatâs too old or if I can upgrade the software on the envoy? Thanks.
Does your Envoy have a web based UI that you can access locally? Thatâs how I found out about the JSON endpoint that the UI uses internally.
My Envoy device has occasionally received software updates (currently on D4.6.22), but the UI and the JSON endpoint have always been there since I got it about 2 years ago.
According to this comparison there are a few different models. I have the Envoy-S Metered which does have this JSON endpoint. Maybe different models work slightly differently?
You are correct. Looks like I have the original âEnvoyâ and not the âEnvoy Sâ. There is a webportal, but it only spits out html.
Guess Enphase felt like they didnât need to create updates for my device anymore.

I also have Envoy R with microinverters but I canât seem to connect it to HA. Could you please share us an example of the code you have that works for you?
Thanks!!!
The easiest way nowadays, if you use version 0.76 or upwards, is the enphase_envoy sensor.
If you prefer to stick with manual configuration using the rest sensor, you could scroll up a bit to see my working configuration.
Iâm using Fronius Symo inverter with Fronius Smartmeter. All data can easly accessed with JSON calls.
And how do you use the data from Home Assistant?
Thanks.
Hi, I am using Hovallâs solar system, it works very well. I purchased the solar panels from Hovall, and they send me the whole solar system.
hey mate - wondering if youâve had a look at the power-wheel custom card, and have any idea how to grab the grid consumption/production from the Envoy-S from the JSON? Lovelace: Power wheel card
I can get the consumption figure, which goes positive or negative depending on the state, however the card doesnât behave nicely - trying to determine if Iâm flogging a dead horse or not, trying to get it to work
Hi @Bluesmell I am looking to get a Fronius inverter solar system soon. How have you interfaced to the smartmeter and inverter? From what I can see these are Modbus, or is that just the interface between those two devices? Do you get the data from the inverter via wifi? Any help / info you could provide would be great. Thanks
@DrewXT That card doesnât work with the Envoy-S sensors as they are. I was using it before a bunch of changes were made that stopped this working for me.
You need to make some new template sensors to get the values needed to work with the card. I donât use this card anymore.
thanks @cjsimmons - what do you use instead of the Power-Wheel card - it is a pretty cool viewâŠ
I have tried custom sensors, and modifying using templates, etc and itâs doing my head in - such a good idea, but has been over-cooked
yeah, itâs a good card, but like you say, itâs over-cooked. Too many features for a now rather small user group. Was good before hand as it was simple and did exactly what you want.
Now I have a custom card that Iâm slowly working on. It just shows the Envoy-S sensors, so nothing special really. Itâs not at a point to share unfortunatly. You might be able to do something with a glance card though.
I hadnât seen that card yet - itâs certainly a good idea to present electricity production and consumption.
I think the Envoy-S should have all the data available required for producing such a triangle view, but the names used for configuring that custom card seem to be misleading or at least not matching the entity names of the envoy integration.
sensor.envoy_current_energy_production)Iâll give it a try later today, and report back.
You are correct. When grid_power was split in to these 2 sensors I stopped using it. I asked why they split and the reason was due to the power meters that they were using have these values split and it was easier for them. I donât fully understand why both couldnât be done, but they said there is a formula to convert the -/+ value of the net sensor on the Envoy in to these 2 new sensors. I really couldnât be bothered with more sensors as the sensors I have is all the info I need. I donât need to know how much itâs costing me. I can get this from my power company.
Alright, here is a simple configuration (Home Assistant 0.87.0.dev0, power-wheel-card from dev branch from today):
I assume that your Envoy-S is already set up and working:
- platform: enphase_envoy
ip_address: <Envoy-S IP Address>
Next, you will need to create 2 additional template sensors to calculate the currently exported/imported electricity:
- platform: template
sensors:
exporting:
friendly_name: "Current Energy Exporting"
value_template: "{{ [0, (states('sensor.envoy_current_energy_production') | int - states('sensor.envoy_current_energy_consumption') | int)] | max }}"
unit_of_measurement: 'W'
icon_template: 'mdi:flash'
importing:
friendly_name: "Current Energy Importing"
value_template: "{{ [0, (states('sensor.envoy_current_energy_consumption') | int - states('sensor.envoy_current_energy_production') | int)] | max }}"
unit_of_measurement: 'W'
icon_template: 'mdi:flash'
And then the Lovelace configuration (using the editor in the UI) looks like this:
grid_power_consumption_entity: sensor.importing
grid_power_production_entity: sensor.exporting
solar_power_entity: sensor.envoy_current_energy_production
title_power: Power distribution
type: 'custom:power-wheel-card'
Et voilĂ , this is how all that looks like:
I see - I havenât been part of that journey myself, but I agree that the cost view may be a bit too much, and it wouldnât work for me anyway because I pay more when buying electricity than I am being reimbursed when selling electricity.
I guess the question would be if it is more desirable to have a generic card that works with many inverters, smart metres, etc. and thus likely requires to add some template sensors to calculate intermediate values, or instead have a card just for a single platform such as the Envoy-S that calculates all the required values under the hood.
Yep, thatâs one of the reasons. I buy my power at different rates, so I could put in the highest price I pay, but then it wont be accurate as most power I buy is cheaper.
you are a dead set legend 
I had tried various ways of getting the import/export to work using the envoy component but just couldnât get my logic correct⊠Iâve got it looking like this now - just need some sun in the morning to see the card send the power to the left 
thank you so much!!!
can this be done within lovelace, and embedded into a glance card?
currently my power glance card looks like this:
to be able to add your exporting/importing arrow as a third option would be awesome for the wifesâ view, as I doubt she cares about the Power Wheel view, which I reckon is pretty cool⊠(thanks again for showing me how to fix it)
