- Notifications when done: Nice, but a beeper would work, too.
- Select program via App, based on what I put into the machine: Occasionally useful when I'm not sure. Also, I can put in my wife's cloths and let her pick the correct program (I did that wrong once and we both don't want that to happen anymore).
- The dryer can load the correct settings based on the washing machine's last cycle. Very convenient.
What's planned (primary reason): Our photovoltaic is also networked, so the plan is to eventually start the cycle when we get energy for essentially free. This saves us money and allows us to use more clean energy instead of the grid mix. I guess the non-smart variant also supports this by setting the "finished in x hours".
What I don't like: Our smart home is fully offline, except for these two appliances. I thought there was a local API, but last time I checked I could not find the info anymore. Also, they sometimes lose connectivity to their cloud (not sure why, maybe hick-ups after that archaic 24h disconnect) and need to be restarted to reconnect.
Edit: Ah, mind we did first replace the old, power-wasting dryer with the new one (amortized after ~2y). Later when the old washing machine started failing, we got this one (which is also better suited for our needs, regarding size; and generally uses less water IIRC). I wouldn't have replaced good units for the sake of smartness. Obviously we could have saved some money by getting more basic appliances, but we had good timing on offers.
