My Siemens dishwasher is smart and it’s got a nice feature where from my phone I can set it to start or finish washing at a certain time. Except, if there is a power failure it forgets the schedule. At the moment in South Africa we lose power 2-4 times a day for 2 hours at a time due to load shedding (useless government and power utility). This powerloss scenario is not a rare edge case here. It’s a pity because I would like to schedule the dishwasher to start after the power is due back (the load shedding is on a mostly reliable schedule), but with this loss of memory, that doesn’t work. Relatedly, on my oven (and the AEG one at my previous place) you can’t turn them on until you set the clock, as someone who lives where there are multiple power outages a day, this seems like the most counter productive “feature” ever, is it actually useful in some way?

If your dishwasher is simply idle until you schedule it, a small UPS may be able to do the job, as during a power outage it would just be powering the electronics and not anything else. Unrelated, but it sounds like scheduled power outages is a great use case for a backup inverter for your home.

  I actually do have an inverter and solar panels and I have my house divided into two circuits, essential and non-essential. Non-essential loses power when grid is disconnected, essential is on UPS. I have 10kw/h of batteries, but I’ve set their minimum charge (while on grid) to 40%. Things on my non-essential: - Geyser - Stove and Oven - Pool pump - Dishwasher - Under floor heating (which is on a timer to only run during sunlight hours). I have been considering moving the dishwasher to the essential circuit, but if someone accidentally runs it when the grid is offline, it drains the batteries very fast. What would actually be nice is if the dishwasher could out the box integrate with some sort of home automation system and it could then make decisions to stop it during power outage automatically.
