Hello all, I’ve been using a DIY Arduino solution using common parts and Plainolddave’s fork ( https://github.com/plainolddave/OpenSprinkler-Arduino ) and as it’s kinda dying on me now I’m looking into either making a new one or replacing it with an OpenSprinkler Bee. What I need is the following: Operate two non-latching valves with a possible extension of a third one so the Bee is adequate enough. As it will be installed at my family’s summer house 200km from where I live I need to control the programs remotely (in my current setup I’m using the dynamic DNS function of noip.com to access the controller).
My questions about the Bee are:
a) Can I edit the programs remotely via Blynk? Do I still need to use dynamic DNS or will it be connected using the API token?
b) What happens after a power failure? As it sits in an empty house in the countryside, power cuts happen and I’m wondering what does the Bee do when the power comes back. Do I need to reprogram it in person like the first time I install it or can it hold its settings + programs, just boot up, perform an NTP clock synchronization and continue as it would before?
c) One cannot mix latching and non-latching valves, correct?
d) One can only use one valve at a time, correct?
Thanks.August 22, 2021 at 6:13 pm #70962
a) Remote editing of programs through Blynk is NOT supported at the moment, this is mainly because the program editing interface is quite complicated and would require a lot of Blynk widgets to make it work, probably not worth it. At the moment you can start an existing program remotely through Blynk but not editing it.
b) If there is a power failure while a zone is open, Bee will not be able to turn it off because Latching valves can stay in the same state indefinitely. For that reason you can consider using a USB power bank or something that can provide backup power when there is power break. All program settings are saved in the flash memory so they will always be preserved over power break. The question really is if a program was running and power was cut off, it would not be able to stop the zone until the power comes back. Everything else, like WiFi settings, program settings, are all saved on flash memory.
c) You cannot mix latching and non-latching on the same controller. But, you can mix and match if they are on different controllers, by using the ‘Remote station’ or ‘HTTP station’ feature. This way you can have a non-latching OpenSprinkler 3.0 control a latching OpenSprinkler 3.0 or OSBee.
d) I am not sure what you mean by ‘can only use one valve at a time’ — you can open multiple zones simultaneously.
