* Shemirat [[Shabbat]] KeHilchata 10:12, Orchot [[Shabbat]] (vol 3 p. 62), and The [[Shabbos]] Home (p. 482) quote the two approaches but do not give a final ruling. Shemirat [[Shabbat]] Kehilchata (10:12) recommends setting the refrigerator to a timer.

* [http://www.yutorah.org/lectures/lecture.cfm/742318/Rabbi_Mordechai_I_Willig/Halacha_Engages_Modernity_-_Part_8_-_Electrical_Appliances_(Part_1) Rabbi Willig (min 33-35)] says that using a water fountain on [[Shabbat]] depends on how long it takes for the motor to turn on. He mentions that one shouldn't use a water fountain which clearly will have the motor go on with a single regular use. However, he did not say this as a definitive ruling but in passing. Note that this wouldn't apply to an electric water fountain that triggers a circuit.

The aforementioned poskim all reject the opinion of the Aruch either because psik reishe dilo nicha leih is not permitted and they also argue that it is nicha leih because had it not been [[shabbat]] one would certainly want the light to help him see (see minchat shlomo page 91), and say that one should get a gentile to do it for him. [http://www.daat.ac.il/DAAT/english/journal/broyde_1.htm Rabbi Broyde and Rabbi Jachter] permit even asking a Jew who doesn't know that the light will turn on as this would fall under the category of mitasek. Iggerot Moshe OC 2:68 and Shemirat [[Shabbat]] Kehilchitah 31:1 also permit hinting to the gentile to disable the light so that the refrigerator could be used for the remainder of [[shabbat]], but not telling him directly. </ref>

# If the light is left on and one finds a way to open the refrigerator the food inside isn't mutkzeh.<ref>Shemirat Shabbat Kehilchata ch. 10 fnt. 44 explains that it isn't muktzeh since turning on the light is merely an impediment (Magen Avraham 518:14 from Ran and Rashba Beitzah 31b) and also there are permitted ways to get a refrigerator to open a refrigerator with a light on.</ref>

* Practical Laws of [[Shabbat]] (Rabbi Rafael Soae, p. 335) quotes Kedushat HaShabbat (Rabbi Moshe Harari p. 79) who says that if there’s no other bathroom available other than one which has toilets that automatically flush when one moves away, one may use the toilet because of Kavod HaBriyot.

* Rabbi Yisrael Belsky in Shulchan HaLevi 7:7 permits using this type of bathroom if there is no other bathroom available, but if there’s another option, he forbids using the electrical toilet.

===Alarm Systems===
# If someone has a grama system (for example [http://www.zomet.org.il/eng/?CategoryID=251&ArticleID=115 Zomet's grama alarm]) set up so that when the door is closed a mechanism will close an alarm system after some time, according to some poskim it is permitted to use it for a significant need.<ref>Minchat Shlomo 2:60:20</ref>

Many poskim would permit closing a door that sets up an alarm system that only go off after some time as it is considered grama.
