Hazman: Shabbos Timer

Hazman is a Shabbos timer for your smart home. Set your Shabbos lights, fridge and oven once, and Hazman switches them by the Jewish calendar: candle lighting, nightfall and every Yom Tov, worked out for your exact location. No more changing timers every Erev Shabbos.

SHABBOS LIGHTS ON A TIMER
"Dining room on 30 minutes before candle lighting." One rule covers every Erev Shabbos and Erev Yom Tov. Pick zmanim or clock times, weekly days, Hebrew dates or one-time dates, and skip any date you like. Works with smart plugs, switches, dimmers and bulbs.

FRIDGE & OVEN SHABBOS MODE
Hazman puts your fridge and oven in Shabbos mode (Sabbath mode) before candle lighting and takes them out after Shabbos or Yom Tov ends. Works with Samsung, GE, Café, Monogram, Profile, Haier, Fisher & Paykel and Miele appliances.

HEAT & AIR CONDITIONING
Thermostats follow the zmanim too: "Heat to 72° two hours before candle lighting", "Cool to 74° on Shabbos morning".

SEE IT ALL ON A CALENDAR
Every switch time for the weeks ahead, in English, Yiddish or both, with the parsha, Rosh Chodesh and Yom Tov marked. Tap a day to see why each time was chosen, and change it for that one day only. Print it for the fridge.

YOUR MINHAG
Candle lighting and nightfall the way your rav says: a Satmar preset, or your own minutes. Chutz La'aretz or Eretz Yisroel, two days Yom Tov or one.

SHABBOS & YOM TOV LOCK
If a light is switched by hand during Shabbos or Yom Tov, Hazman can put it back within seconds. After a power outage, everything is set right again.

TURN LIGHTS ON OR OFF ANY TIME
During the week, switch any light, room or group right from the app, with one-tap buttons and home-screen widgets.

SHARE WITH FAMILY & SHUL
Invite people by email. Each gets their own sign-in, with only the lights, rooms or appliances you choose. Great for a shul or bais medrash timer.

WORKS WITH
Kasa and Tapo smart plugs, switches and bulbs, Samsung SmartThings, Samsung fridges and ovens, GE Appliances (SmartHQ), Miele, and thermostats like Honeywell Home. Hazman never sees your passwords.

ALSO ON THE WEB
Everything also works at hazman.app from any browser.

Notifications: Hazman tells you on your phone if a scheduled light didn't switch, even after trying again. The 'Open Hazman' button in emails now opens the app.
