Atmoce
Solar, battery and grid with smart local battery control.
Bring your Atmoce solar and battery system into Homey. Solar production, battery level and every watt you take from or send to the grid appear live in Homey Energy, read straight from the Atmoce gateway on your home network, without the cloud. The Energy flow widget shows on your dashboard how the sun charges your battery and powers your home, and when the system reports a fault, a battery needs attention or the power goes out, a clear message lands on your timeline.
Then put your energy to work with Flows. Charge the battery when electricity is cheap and save it for the evening peak, cap export or solar production when prices turn negative, and act the moment the battery reaches a level or the panels start producing. Works with the M-Combiner MC100 and MC100-T and the M-Gateway MG100 with any Atmoce battery: switch on Modbus-TCP in the Atmozen app under Settings, 3rd Party System, and Homey finds your gateway by itself. The MC100L Lite has no local connection and is not supported. Atmoce and Atmozen are trademarks of ATMOCE Holding B.V.; this app is not affiliated with Atmoce.

Grid meter
Solar surplus of at least Power W for Minutes minutes
Surplus is the solar power that flows to the grid: what the home doesn't use and, with a battery, what the battery can no longer absorb. It is averaged over 2 minutes so a passing cloud does not count. Starts once when it stayed at or above the power the whole time. Use your appliance's power plus about 200 W, and switch it off with "Solar surplus has been gone for a while". The grid meter setting "Battery first up to" decides whether battery charging counts as surplus.
Grid meter
Solar surplus has been gone for Minutes minutes
Starts once when the home has taken at least 200 W from the grid, or from the battery if you have one, the whole time. The battery counts because a full Atmoce battery covers dips itself, so an appliance started on surplus would otherwise drain it.

Home battery
Charge the battery at Power W
Homey keeps control of the battery until you return it to the Atmozen mode.

Discharge the battery at Power W
Homey keeps control of the battery until you return it to the Atmozen mode.
Home battery
Pause the battery
The battery neither charges nor discharges until you return it to the Atmozen mode.
Home battery
Return the battery to the Atmozen mode
Ends Homey control and any forced charging or discharging. The battery follows the self-consumption or time-of-use mode set in Atmozen again.
Home battery
Charge the battery to Level% at Power W
Forced charging may take power from the grid, even when grid charging is disabled in Atmozen.

What’s new
Version 1.0.2 — Solar surplus on the grid meter: new Flow cards to run appliances on surplus (battery first, also without a battery) and the setting "Battery first up to". The Energy flow widget shows when the battery will be full or empty. The target power sliders are hidden against accidental taps; Flow cards and Homey Energy work as before.
Atmoce
Atmoce is not compatible with the selected Homey.
Atmoce will install on Homey shortly.
