Erik, I don’t know the OP’s reason, but I have a clear and definite need to turn off the sync module. It doesn’t really matter what the reason is, trust me that I need to do it, and disconnect my whole system overnight.
For what it’s worth, and because you asked, my installation is completely off grid, and in winter, when the days are very short, and the weather is poor and the sun angle low, my rather large, for the purpose, 200W solar array, and 12V 220Ah battery bank, simply cannot keep up with supplying power to all of the devices associated with the Blink system, particularly the MiFi router.
I use around 5W at 12V, total, whilst Blink sleeps, which is good and low, but on a rainy winter’s day, I maybe get 7W, for 4 hours. Even on a great day, due to the low sun, I will only get 100W for a few hours. As soon as it goes dull, that’s it, no power, so for two thirds of the day it runs entirely on my battery bank.
After a couple of weeks of poor weather, the battery bank gets dangerously low, in terms of causing long term damage to the cells, less than 50% capacity. At this point, I need to turn off all loads, when dark, which I do with a smart switch, with an inbuilt timer, programmed accordingly, and activated remotely.
In this way I can maintain sufficient power to run the system during the hours of daylight. In this situation, this is adequate for my needs, because there is zero chance of anyone going near my remote site during the hours of darkness. During the day is a different matter, people may and do go and have a nosey around, but night, way too off the beaten track, a mile from the nearest road, over fields, no paths, in the dark, no chance, none at all.
So off at night is essential for me, but I don’t want that to increase the load on the batteries in the cameras, by causing them to flash all night long, which is effectively for two thirds of the time, in the depths of winter.
I have a four camera system there, and despair at the thought that all four of them are sitting there flashing away, especially my tree camera one, which I wanted absolute maximum battery life from.
So, rather unusual, but definitely required, in my case.
Riccardo, thanks for confirming that the XT’s now also do this. Clearly I can check this, because I have several XTs at home, which I’ll do shortly. They definitely didn’t used to do this, only for firmware updates, so it must have come from a change of firmware, at some point.
Now that I’ve been advised the XT also does this, I’ll test in a minute, I will try to find a way to stop it blinking. As you say, disable motion first, may well do the trick, which I could also do by schedule. Good idea, thanks.
I’ll confirm if there is a way to stop it, now that I can test with the XTs as well. If I can’t, I will be writing to support, to ask if it can be optional.
