It's been remarkable watching this firmware project grow over the last year. I've found it invaluable for our product development as well as personal projects around the property.

Can't wait to see what the future brings!!

andy

I'd really like to get input from all of you! Good, bad, indifferent - it's all valuable information for us as we move forward. There's been a lot of manuals and schematics downloaded, so I'm assuming many have had the chance to review and digest the design. We're running a promotional sale at the m...

andy

Thank you for your input, Costo - I really appreciate it! :D The board was designed for SMD components to keep it as compact as possible while still being something a competent DIY'er could build. This was my first exposure to SMD assembly, so I got to learn a new skill. Finding the components was a...

andy

Really sorry, all!

Small glitch in the Matrix, all is well now. I've tested the fix and it works.

Dave mentioned in http://www.esp8266.nu/forum/viewtopic.php?f=5&t=1793 in the Hardware section there's a new ESP8266 control board available. This is something we've been working on over the last several months. It scratches a lot of our itches; primarily a small footprint that can take in a lot...

All

Just to make things easier, here's a link to the ESPEverythyng-885 manual.

Let us know what you think!

andy

Look thru http://www.esp8266.nu/forum/viewtopic.php?f=4&t=1431. Let us know if this helps.

andy

Okay, the R78 may be the problem. I'm using 105. If you look on the site now, you'll find version 108 is the latest stable version. Try uploading that and see if it helps.

andy

A quick Google search turns up some recurring problems if you are sending more than 84 characters to ThingSpeak. See http://www.esp8266.com/viewtopic.php?f=8&t=1952 for a discussion on that. You may want to check the string length you're trying to send.

andy

Find dduley on this forum. He's big into 3D printing.

andy

Bump - anyone?

andy

I don't believe you can. ThingSpeak requires a 15 second message delay, so that pretty much guarantees you cannot sync them up.

andy

Thanks for the suggestion. I previously had Mosquitto installed on a Raspberry Pi and working great. The problem is my pi is good for a week or two, then corrupts the micro sd card and has to be reinstalled from scratch and configured. Yes, there are ways to harden a pi to avoid these issues, but I ...

I'm trying to set up a cloud-based MQTT broker, and have settled on CloudMQTT (https://www.cloudmqtt.com) as a starting point. I've started with the Cute Cat free plan to try it out and see if I want to take it farther. My question is: How do I connect to it? I've tried configuring the ESP as Domoti...

andy

That's a piece of cake too. Replace "all" with either "sun" "mon" "tue" etc - you get the idea.

andy

GPIO inputs are 3.3V max, except Tout, or ADO, which is 1V max.

andy

Sure. The following assumes GPIO 5 going low turns on your geyser and high turns it off. Adjust the code as appropriate for your setup. on Clock#Time=all,05:00 do GPIO,5,0 endon on Clock#Time=all,08:00 do GPIO,5,1 endon on Clock#Time=all,17:00 do GPIO,5,0 endon on Clock#Time=all,20:00 do GPIO,5,1 en...

andy

I may have found a clue. Line 27 in _P003_Pulse.ino states: Device[deviceCount].VType = SENSOR_TYPE_SINGLE; ...which indicates to me it may only report one value to ThingSpeak (my issue in another thread) and may only apply a formula to the first result. If you look at line 23 in _P005_DHT.ino, you'...

andy

That's really cool! Now I can test if the pump is on to know it's safe to inject chlorine into the pool plumbing.

andy

I've got a momentary switch between GPIO 4 and GND, but am reading it like a pulse counter. It's working so far (have to set mSec Debounce to 2000), but my problem is getting the values to ThingSpeak. The Pulse Counter returns three values: Count, Total, and Time. Count is the number of counts recei...

andy

I've been having problems with thingspeak too; sensors that report 2 fields work ok because that is sent in one message, but all subsequent messages are sent too quickly for thingspeak. To prove this, i added a 15sec delay to the end of the thingspeak publishing routine, and now all sensors are wor...

andy

Booleans do not work, so just set up enough rules. Also, you may want to define on and off events, then call them with rules: On thermon do mcpgpio,23,1 gpio,0,1 endon On thermoff do mcpgpio,23,0 gpio,0,0 endon on temp1#Temperature<38 do if [occupied#Output]=1 event,thermon endon Creating events fr...

I was wondering if its possible to use an 'OR' function here is my attempt at a thermostat control based on occupancy (the Or doesn't seem to work?) on temp1#Temperature>40 or occupied#Output=0 do mcpgpio,23,0 gpio,0,0 endon on temp1#Temperature<38 do if [occupied#Output]=1 mcpgpio,23,1 gpio,0,1 en...

Does this unit have many tasks? I'm measuring a DHT11 and a ds18b20. I've got an I2C bus with an ADS1115 and six relays on it. TASKS: Uptime Wifi Strength DHT11 Temp & Humidity ds18b20 temperature 0.5 - 4.5 VDC signal on ADS1115 RULES: On boot set pcfgpio 1 & 2 to 1 On Clock#Time = 8.00 set...

andy

Sometimes my pump relay does not trigger on the Clock#Time event. It seems there are times that more than a minute elapses before ESP reports a new time. For instance, I will see 13:59 registered in the log, but it will miss registering 14:00. It will register 14:01, but by then I've missed the 14:0...

andy

Any movement on this yet? I'd like to see it implemented also. I can Tweet a message via ThingSpeak, but I'd prefer something not reliant on a third party if possible.

andy

I want to display the pool water temperature realtime value and trend. I'll have that on my personal website; friends and family will be able to tell what the water's like from where ever they are. I will also use an average daily value to compare against chlorine load, but that's down the road a bi...

andy

How would you guys tackle this one? I'm using a db18b20 to measure pool water temperature in a pipe near the pump. When the pump is running, the water in the pipe is the same temperature as the water in the pool. When the pump is off, the water in the pipe is static and the temperature begins to dri...

Thanks to dduley for figuring this one out! :D In ThingSpeak, you set up your channels as Field 1, Field 2, etc. You can add a name for each field, but the magic is the field number. You need to put the Field Number as the IDX/Variable for each device you want to chart. Thingspeak Configuration.jpg

andy

Okay, slight brain fade on my part. I see there is a ThingSpeak protocol (see http://www.esp8266.nu/index.php/EasyProtocols#ThingSpeak). I've added my API key and filled in the IP address and port as shown in the link. It's definitely writing something to ThingSpeak: HTTP : connecting to 184.106.153...

Original Post: I've been searching for example entries for the Publish Template to send data to a Thingspeak channel. So far all I've gotten is confused. :?

andy

Okay, that's working now. :D Is there a way now to test just the time, instead of the day and time combined? For instance, if I want a relay to trigger every day at 08:00 for 4 hours, I currently have to either set up seven rules to trigger on each day at 08:00 with a 4 hour timer, or wait for (say)...

Fair enough, I can work with that too. Very cool feature.

Just created an initial Wiki page to get you started: http://www.esp8266.nu/index.php/EasyGlobalSync What a cool feature! If this works the way I hope it does, I've got some great uses for it.

I don't think he's got a GPIO 4-5 swap issue. He's getting the right result from the output of his sketch, so the I²C interface is working. Look at _P024_MLX90614.ino, line 30 and 31. It takes a value, multiplies by .02 and subtracts 273.15. If you work ngc's result of 1037.55 backwards thru the equ...

andy

Thank you, Martinus, I appreciate the reply! I really like the rules option. In my application it's important for the ESP to control relays based on inputs in case the wifi is lost. Otherwise I would handle it thru MQTT. I hope 'experimental' doesn't mean they're considered expendable, and work cont...

andy

First things first - did you put an entry in the IDX field? See the image and make sure you put something in the IDX field:

andy

Make sure you enter some value for IDX/Var: This number is used with Domoticz MQTT. You will need an entry there even if you do not use Domoticz. I usually just throw in 110 or 150 or 222 or whatever three digit number strikes my fancy. As for graphing, no, ESP doesn't do that. You will need to conn...

I'm using NTP: us.pool.ntp.org with -8 Timezone Offset and DST enabled.

The Rules section starts around line 1735 in Misc.ino, NTP is line 1670 in the same file. I'm not quite able to tell how the code is working.

andy

Does anybody know if it's possible to put modifiers in the Event call? For instance, if I could do something like:

Code: Select all

on right(Clock#Time,5)=10:55 do

then it would ignore all but the 5 rightmost characters. Of course, that doesn't work, but something similar perhaps?

andy

I seem to have gotten this to work on an ESP I have at the office. I'll have to check the differences with the unit I have at home, but here's what I've got to work: NTP Hostname: us.pool.ntp.org Timezone Offset: -8 DST: Checked (Daylight standard time in effect now) It did require a hard reboot, bu...
