![]() One thing to note is that it can take around 3 mins to turn the rads on/off with these valves so may need to offset the temp that turns them on/off by a degree or two to stop the room getting too hot. Sorry that the above is a wall of text! It’s just a concept at the moment, but I can’t see why it wouldn’t work? 11:00:14 PM Stop alarm Fullscreen 10:45 PM : : Set alarm for 10:45 PM Can I use this page to wake me at 10:45 PM Definitely You can quickly set an alarm for 10:45 PM in the evening - for FREE In fact, an alarm for quarter to eleven PM is preset on this page. You can then put a random temp sensor of your choice into the room, and then get home assistant to turn power off to the radiator when the room is up to temp (you could even wire in a PIR to the sonoff so if there is motion in the room it will turn the radiator on).Īs a bonus I plan on using the button on the sonoff to act as an override so if it’s a lot colder outside and you feel chilly, you can press the sonoff button and it will turn on the boiler and radiator for an hour or so, or until its a few degrees warmer. Wire those into/through a Sonoff, and into a 13amp plug (downside = you lose a plug, and it must be near the radiator). Which are two wire normally closed, and M30 thread, so should screw straight onto where the existing TRV is on your radiator (provided youve had valves in the last few years). # by leaving out initial, the time is restored from recorder In due course, I will post a link to my whole configuration! As i have separated my config, it will all need placing in its own areas in your own config, should you choose to give all of this a go. Ive placed all of my YAML code into one set of code which is below. To top it off, ive set up an Alexa skill to be able to do all of this via voice. When the sensor value changes, an automation sets the climate based on its output. The output of my sensor is then used for an automation. All you need to do is to enter a custom message (optional) and select the sound you want the alarm to make. these checks are based on the Input select timers, and the binary sensor. 10:45 AM : : Set alarm for 10:45 AM Can I use this page to wake me at 10:45 AM Definitely You can quickly set an alarm for 10:45 AM in the morning - for FREE In fact, an alarm for quarter to eleven AM is preset on this page. Climate is set for the lounge, and i have created a sensor which has a long convuluted check, to tell me which part of the week we are in. I use Input Select to set my timers, Input Number to set my temperatures and have ’īinary sensor’ set up to tell me if we are on a weekday or a weekend. I have a Sonoff basic controlling the heating as a switch, and a DHT11 connected to a sonoff in my lounge, to give me my heating zone which is the area i use to base my heating on. This is my code: import React, from 'react' Ĭonst = useState(2) //countdown 2 hours.Ĭonst finishHours = startDate.getHours() + 2 + startDate.getMinutes() / 60 + startDate.getSeconds() / 3600 Ĭonst currentHours = new Date().getHours() + new Date().getMinutes() / 60 + new Date().getSeconds() / 3600 Ĭonst remainingHours = finishHours - currentHours Ĭonst remainingHour = Math.floor(remainingHours) Ĭonst remainingMinute = Math.floor((remainingHours - remainingHour) * 60) Ĭonst remainingSecond = Math.Ive had a look around on occasion, and never found a complete option for a central heating system, that has adjustable timers, weekday and weekend settings, and the stuff youd like from a HIVE like system. For example, after one second elapses the function is called 2 times, one second later the function is called 8 times, then 32 times, and so on. And the number of times it gets called increases exponentially. The problem I am facing is that the function getTime() gets called multiple times every second. ![]() These 3 variables are then used to display the remaining time on the screen. For example, 10:45:32 will become 10 + 45/60 + 32/3600 = 10,76.įrom there I can calculate the remaining hours, minutes and seconds and assign these values to variables: rHour, rMin and rSec. You can also easily launch online timer from the list below pre-initiated timers. Hour Need a custom timer just select the time values and start your timer above. Simply select hours, minutes and seconds and hit 'Start Timer'. To make calculations easier I format both variables in hours. You can use online stopwatch to countdown from any time and get alarmed. FJM set for Non-Comm tonight (10:45 pm ET) will be live-streamed. CurrentHours is equal to the current time. Finishhours is equal to the time that the countdown timer should be zero. Search Change Language A cool little 45 Min Timer Simple to use, no settings, just click start for a countdown timer of 45 Minutes. In this function, I have a variable named finishhours and a variable named currentHours. ![]() I tried coding a countdown timer as follows.Įvery second the getTime() function is called.
