## What is Elios4you?

This application can be used also for demonstration purpose without the need of WiFi connection with our Elios4you electronics.

Elios4you is part of the fusebox wiring at home and with two CT measures the electricity produced, the energy bought from and sold to the grid and calculates  the consumption. The data is transmitted by Wireless technology locally to Tablet, Smartphone and possibly to the ADSL router that sends them to the 4-CLOUD*. In this way the data is current and available anytime on any device, anywhere you are.

Key features:
A unique measurement device for:
● energy generated by the plant
● energy bought and sold to the grid
● household consumption (calculation of the Energy consumed by the customer)
● available self-generated power

For single phase and three phase plants up to 30 kW:
● WiFi technology
● Universal: it can be used with all the photovoltaic installations, independently from any inverter and any meter installed
● Easy to use and install: retro-fitted without any tampering
● Transmission of the measurement/calculations to Tablet/Smartphone/Pc/4-CLOUD through Wireless technology each 10 seconds
● Data storage of last 60 days with new updates each 15 minutes

It can report possible service anomalies: 
● inverter connected by clean contact (if available)
        thermal magnetic circuit breaker or differential circuit breaker by auxiliary contact
● loss performance after 48 hours  

In case of installation or operation problems, please contact our customer service.

### 4/5 — Mostly great - used for 7 years (so far!)

*2022-10-23, version 3.1.0*

Overall this is a great app for monitoring your solar PV system and household power usage.

Currently running on iPhone and iPad, with iPad wall mounted to show the household when’s best to used appliances.

Updates that would really help.

Link system to auto iCloud backup, if you change devices you can loose a LOT of data of not backed up.

Following up from this, the 4cloud system seems to have all the data, but there is no way to restore from that to your phone.

Finally, having the ability to show on 2 screens while at home would be great.  There may be a work around for this, but not ideal.

### 1/5 — App won’t load

*2022-08-15, version 3.1.0*

This is not the first time this app has stopped working! Had it on my iphone11 now tried to connect it to iPhone 13 and no success. Even had BT come out think it was my home internet which it isn’t. Tried it on an iPad and still not able to connect to app. This is one of the worse apps I ever had to use.

### 1/5 — Needs Updating as doesn’t connect anymore

*2020-07-21, version 3.0.3*

As the title says, the app designers don’t update this regular with IOS updates. 
The app is fine when working.

### 5/5 — Great when it works!

*2019-09-27, version 3.0.1*

Following iOS 13 update on iPhone, app crashes on start (I did update the app to version with iOS 13 update). Hopefully 4-Anika will resolve this quickly.
Redcap is great, and app makes it easy to control devices attached to it, as well as monitor PV performance and power use. Unfortunately, can’t do any of that now that the app isn’t working.
Would have been 5* if update hadn’t broken it.
Updated review to 5* as iOS 13.1 update has fixed crash.

### 3/5 — Firmware update renders Power Reduce inoperative

*2018-06-22, version 3.0.0*

June 2018 - The latest firmware update fails every time. As a result the Power Reducer is not working and the supplier is unable to offer any solution. When it works I rate it 5 star but in this condition it is worthless.

### 5/5 — Great.... BUT

*2018-06-07, version 3.0.0*

Having had Elios4you for 4 years, the major flaw is with saving of data. 
Several times I’ve had iPhone crashes which needed re-install and resulted in losing ALL data. 
Yes, I know there is an option to back up before reinstalling, however, that’s useless if your phone dies, lost, crashed....

### 5/5 — First class

*2017-12-06, version 2.7.9*

We use it to monitor a customers energy consumption. It enables us to divert energy flow to the grid into the underfloor heating and hot water instead. It handles energy generation in excess of 12kW. We can access across the internet from 3 different iPads and a smart phone. Excellent graphs using 15 minute averages.

### 1/5 — All gone wrong

*2017-05-20, version 2.7.6*

Can't update iseless

### 2/5 — Oh dear

*2017-03-12, version 2.7.6*

It was all working fine until this firmware update. Now all my smart switches have been deleted and some app buttons are in Italian.

### 1/5 — Good app, needs work!

*2016-11-02, version 2.7.3*

Great app, and a reliable clever device, but some functionality is missing!  For the cost, I would really like to see:

1) an API of some sort to be able to extract usage into other applications.

2) a way to check generation relay status via IP, so other home automation systems on the network can take action (ie turn on / off devices!) dependent on energy generation!  Currently everything is locked up inside this app, despite me owning the hardware.

3) usage on more than 1 device. It's limited currently to pair with one phone. There are multiple phones in the house and an iPad, it should work on all these devices!  It's a bit limiting...
