Use the app as last option

Months of feedback and nothing really solved or improved.
Update, not gonna send feedbacks anymore considering you even closed the ticket as resolved while….

The app doesn’t work for solar panels

The app doesn’t show the production of electricity by solar panels, Bluetooth doesn’t connect well, even close to the device.

Smart actions don’t work

The smart actions to turn on and off the heat pump are unreliable. Ive set the unit to heat during the day and shut off when off peak power ends. I’ve just noticed the heat pump has ignored all smart actions for the past couple of weeks and its been heating at night. Useless. The support is some useless AI that send you to equally useless support articles. Dont buy if you want something smart. It does heat the water though. This is not a tech company. Do not expect good tech.

Smart Actions stopped working

I had smart action setup to utilise my free electricity time from 11am to 2pm. It was fine until probably new update. I don’t check the app regularly and today suddenly I realise that the heat pump was turned off since last 3 days. I tried to re setup smart action but still no luck. Did not trigger at all. Pretty frustrated with this new update

Useless device

The app seems fine to me but using Bluetooth to connect to the device seems silly especially it is outside the house. The app can’t maintain the connection for an obvious reason with Bluetooth limited range. This device does not allow me to view the power consumption from anywhere anytime.

Update —

I feel unfair to give 1 star for the app review when the issue is actually with the device Bluetooth connectivity so I changed the review to 3 star.

Update Nov 2025
Couple of annoying things - inability to change peak/off peaks times period in the app. It was hard coded.
Inability to change battery. ( which are regular AA )
