There are definitely 2 output types for the alarm function. I am fairly sure whats going on now after searching the web. Not sure if this is the best place for this or to start a new topic. Wondering if I am all wet here and need some special circuitry here or what. I "think" it is outputting the square wave version instead of an interrupt version. Looking at the DS3231 datasheet I get the impression there are 2 output modes for the INT/SQW pin. Only then does the INT/SQW pin on the RTC reset to 3.3 volts. I have to momentarily ground the ESP RST pin to wake it. Because the pin does not go low and back to high the ESP does not reset and wake up. The idea is the alarm pin pulses the RST pin on the ESP to wake it. 035 volts and stays there until I assume its reset by the ESP. When the alarm time occurs the INT/SQW pin goes to about. The RTC module seems to have a pullup resistor keeping the INT/SQW at 3.3 volts. What I seem to be getting is a very low voltage that stays there until the ESP "tells" it to go off. I was under the impression that the alarm trigger was an active low momentary pulse. The alarm function is one of the things I was most interested in and its working but not as I expected it to. The RTC module seems to be working as it should. I have a couple things that are a bit fuzzy though. Thanks in advance.įinally got around to testing my setup with this plugin.

If you don't have somewhere to put it for download I can set up an FTP account for you. Would it be possible for you to make a bin file with this plugin in it? I have not mastered the self compile thing as of yet.
Rules / Clock#Time will work, and system values like %syshour% may work. It disables NTP through "Settings.UseNTP" so any functions that depends on it - such as "Local Time" on main page, and several Clock plugins WILL NOT WORK! And i did not see any solution without modifing the current ESPEasy core functions. I struggled a little with timezones when updating from ntp to rtc, but now i think it is working.Īlarm mode works in theory, but it is low level active, so pullup needed on the other side, i am curious how can you use it for deep sleep. It keeps time when power down, even without NTP server, and shows temperature information, the latter is new to me. I'm just finished a test version of my DS3231 plugin. I'm sure folks would come up with multiple use cases for it. It has configurable timers and could be used in battery powered sensors to get around the 71 min ESP limit. I have requested a plugin for an RTC a couple times.
