Home Automation: Power timer with internal battery

[kyk]

Копирую своё сообщение. Может, кто-то этим вопросом уже интересовался?

I am looking for a (digital) power timer, which will turn on/off 100W appliance(s) on schedule based on time of day. Say, I will set a turn-on time to 3pm and turn-off time to 8pm and it will go automatically every day.

One important requirement is that it should have an internal battery which will keep the internal clock running when/if the external power is down. So a power outage lasting, say 1 hour or 12 hrs would not affect the internal time and settings.

Will your "Intermatic DT620CH" and/or "GE 15089" timers do what I need?

У меня такой http://waterheatertimer.org/pdf/Noma-05 ... manual.pdf" onclick="window.open(this.href);return false; но это старая модель. Батарея внутри есть и время держит до года (с неким уходом, конечно). Сейчас есть новее http://www.canadiantire.ca/en/pdp/noma- ... xUm8D_2aUk" onclick="window.open(this.href);return false; и написано что тоже с батареей

" I was using different mechancal and outdoor timers I had picked up over the years for indoor christmas lights. I decided to change them all to this type of timer. I purchsed 4 of these last year and had to take all of them back for exchanges and 3 of the 4 replacements now do not work, in other words, 7 of 8 have failed. The internal battery has been ok in all of them so it seems there is a problem with the internal electronics. They lose their memory, or they just fail to turn the lights on or off at the times programmed. I have gone back to using other timers I already owned including CTC prod. # 5288142 and # 5288706 and a simple mechanical timer. Given the poor reviews and overwhelming negative comments on this product, I question why CTC continues to carry it. "

гирлянды внешние по праздникам переключает.
когда праздников нет, выдергиваю из розетки, внутреняя батарейка спокойно держит прописаный график включения до следующего праздника.
