I know how you feel. I usually just start with someone else's code that is at least similar to what I want to do, and then hack it to work for me. Basic structure of an App is
get user input for all of the devices needed to run the app
subscribe to events from those devices, and supply functions which can handle the events from the subscriptions
add logic to the event handler functions
Add scheduled functions which can cause the app to wake up periodically even if no new events have come in.
At least, that's how I approach a basic groovy app for Hubitat... There are lots of great community developers that I am sure would help you along the way.
Maybe we should work together...
I have a Lennox iComfort furnace, and I am also making smart registers with an ESP01 and servo.
I want to do the exact same type of control, but I am changing my heat/cooling setpoints to the furnace via presence. I do not plan to change the room setpoints via presence.
Excellent offer. So we don't hijack Dan's topic, I created a new topic for this HVAC zone control app. I will add my thoughts in the new topic when time allows.
@ogiewon hope you don't mind hijacking your thread for a single post
I had on a drawer a set of arduino and related similar parts that are brand new and never used. This parts were to be used on a project that never materialized.
So I'm selling them away to any EU customer that is willing to pay for shipping and roughly the parts at a discount price.
The parts I have are:
5 x 19mm Flat Pins Type Switch Connector
3 x 19mm Metal Push Button Switch Waterproof Latching Self-lock 5v Multi Color

As such if anyone is Interested let me know. The asking price is 35€ plus shipping. ( For everything).
P.s some stuff is not even here and is on transit but should arrive in the next couple of days.
So, I have new info on the saga of the locked up board @ogiewon. I don't know why, but 3 of my boards locked up yesterday night. I went around and reset 2 of them manually but the third was out in the garage and I didn't immediately go out and rest it. I kind of forgot about it being locked up. Well, I log in this morning and BAM it's back...all on its own. I don't know how or why but it appears that eventually it was able to reestablish communication with the hub. This just gets stranger and stranger.
I must admit following this conversation is quite intriguing. You all are doing incredible things with @ogiewon’s app and platform. I look forward to the final results as I would like to the DIY shades and also am intrigued by the zone comfort solution. Keep up the great work!
Having issues with a BME280 sensor that was working on the Adruino/ST before I switched over to Hubtat. I had turned commented out the lines for the BME in my sketch (god only knows why at this point) anyway, uncommenting and restarting the Arduino got me nowhere. Watching the serial monitor I assume I should see the Arduino realize the sensor is there and show the sensor readings. The sensor is outside in an unheated enclosure. I live in Michigan and I assume it can handle the weather. I have power to it. What else can I check ?
These would be good additions to the Child Pressure Driver as user preferences. If you’d like to give it a try, you can look at the Child Temperature driver to get some ideas on how to accomplish this.
My high torque digital servos finally showed up, so I am back to testing with the new EX_Servo driver. I found that the default min and max microsecond values used by the servo library are way off for these servos. at 0 degrees the servos were trying to travel beyond their physical stops, and at 180 degrees they had a lot of unused travel. I took the simple way out and modified EX_Servo.cpp to include min and max values in microseconds.
m_Servo.attach(m_nPinPWM)
was changed to
m_Servo.attach(m_nPinPWM, 850, 2725)
where the two values need to be tuned to the specific servos in use. Default values are 544 and 2400.
I am posting this in case someone else runs into the same issue. At some point I might modify EX_Servo to allow optional arguments for specifying these values in the sketch. That would enable fine tuning for a mix of servos that have different min and max timing needs.
Dan, I propose the following changes to EX_Servo.cpp:
if (!m_Servo.attached()) {
// m_Servo.attach(m_nPinPWM);
m_Servo.attach(m_nPinPWM, 544, 2915);
}
// if (m_nTargetAngle < 0) {
// m_nTargetAngle = 0;
// }
// else if (m_nTargetAngle > 180) {
// m_nTargetAngle = 180;
// }
// m_nTimeStep = (m_nCurrentRate / 180); //Constant servo step rate assumes duration is the time desired for maximum level change of 100
m_nTimeStep = (m_nCurrentRate / (m_nMaxLevelAngle - m_nMinLevelAngle)); //Constant servo step rate assumes duration is the time desired for maximum level change of 100
I believe this will be completely backwards compatible for users that specify angles in the 0-180 degree range. For those that want to specify start, min and max microseconds in the range of 544 to 2915 instead of degrees, this gives a new level of control. It takes advantage of a feature I found in the servo library where values are interpreted as angle or microseconds depending on the value itself.
This works so far on my bench specifying start, min, and max angles in the sketch as either degrees or microseconds. I need to look for ways to break it, but so far I like it.
Yeah, I'm using two of these currently. Didn't have to do anything custom like that with the servo library for mine. They work perfectly as far as I can tell.
