I bought a basic Sonoff switch (no POW) which has the power on state functionality. Nothing is connected to it and it just sits on power. The power on state is checked so this basic switch comes on when power is restored. I then programmed a scene and linked all POW R2s to this basic switch.
Power comes on, the basic switch turn on (through the power on state) and all POW R2s are following and turning on as well. This is just until they release the new firmware. I will then reuse the basic switch for something useful.
The R2 as well as the POW are totally OK for low power usage like lights. Just be aware the POW and POW R2 are a lot larger than the Basics. I use both the POW and R2 for high power applications (hot water (1.8kW) and electric vehicle charger (3.5kW)) and they work just fine. I have modified the POW for the charger though as it gets pretty hot in summer time here in Australia and removed the back of the plastic enclosure to allow some more airflow. This works great and I have no problem with heat any more...
The R2 still lacks the Power-On-State though. Firmware is still on 1.0.0. I've contacted their support and this feature is in development for a future release but no ETA at the moment.
I want this feauture too. Please add it in next firmware
for those that are using it on a freezer/fridge, I have a little idea.
Just go to the settings and add a lot of schedules...
mo-fri 09.00, power on
mo-fri 11.00, power on
mo-fri 13.00, power on
Worst case scenario, your freezer is out for 1 hour and 59 minutes ;) (and that should not be a problem)
I really hope that Itead is taking this seriously :(
Here you can see the version and the power on state
Do you really think that is a solution?
you can not enter 24 alarms, that is, that plan does not work that well.
SonOff POW R2, is in theory more current than previous versions, how can it be that it lacks this important option that already had the previous versions ?.
I'm really disappointed with this device.
It is incredible that this function that is so basic and important is not added in firmware 2.6.1.
another thing, where can you know what is the improvements of the updates? the typical chages.log
Please implement this feature!! it is very necessary!!!
