Let's Control It

DVM = digital volt meter If you think 4 volts is OK for the ESP then go ahead, BUT make sure you have lots of spare of ESP modules :-) When the spec on a module specifies a MAXIMUM voltage then do NOT put more than that into it, otherwise the smoke will come out, simple design guidelines, no rocket ...

rayE

Yes i checked your drawing, the TP board has NO VOLTAGE regulation, your drawing will WRECK a bare ESP module when the battery is fully charged. as for an INA board, iv never heard of it and NO IDEA what it is? Maybe do a little more homework before letting the smoke out of the ESP module :-) http:/...

rayE

DANGER!!!!!!!!!!!!!!!! Where is the voltage regulator? 4.2 volts (a fully charged LiOn) WILL KILL a bare esp module (been there and done that

unless your using a PCB with a vreg? Lots of detail missing out of your drawing?

rayE

what is the I2C module?

rayE

Just a thought, if the pulse counter device digital input from the flow sensor is configured as a D/O (in the device driver) that would cause current sink problems and probably reboots. Look at the horrible scope graphs previously presented?

rayE

My setup:
v2.0.0-dev12

Device = Pulse Counter
I/O = CH5
Type = delta/total/time
Mode = Rising
Delay = 10s

rayE

Hi Jacek, What value pull up resistor is on the flow sensor? i take it the capacitor is 0.1uF ceramic? I use this type which gives nice square waves with 3K3 + 0.1uF, works fine on a PIC BUT not with the pulse counter device, iv also tried a signal generator and it still constantly reboots, a firmwa...

rayE

I will second that. My ESP12E has adequate decoupling and built on a PCB. It's been running non stop now for 3 weeks with a different application and no reboots. Start up the pulse counter device and it reboots at least every 30 seconds.

rayE

OOps, correction.

Sorry for the delay. My rules setup. I run these by sending event, SerialSend through the serial port, i guess you can run from a timer instead. //---------------------------------------------------------------------------------------------------------------------- on SerialSend do SendToHTTP 184.10...

rayE

I noticed this odd behavior as well. My fix was to NOT use a thingspeak controller. This is what i did. 1. sore the energy data in a quad dummy device. 2. Send the data with a SendToHTTP command. This can be set up in a rule that is triggered by a timer. If you want ill post the rules i use for my s...

Hi,
I had the same problem, some others did not. Thread here. Hope it helps.

I second a request for a WiKi write up on how to do this. This functionality will make ESP Easy totally AWESOME (more so than it is already)

Ray

rayE

I should have added that there are no devices set up for this, like dummy's or ser2net (tried all that but it was like rocket science for me) BUT you need to set the serial debug level to 2 or greater (check this, it may be 4?) so that the rule responses are passed out through the serial port.

rayE

Hi All, Iv been on the ESP Easy uphill learning curve for around 2 weeks or so now. My main use for this firmware is the real nice web configurable front end. At the present moment im developing my own energy/utility monitoring sensors using the ESP module and a VERY low cost PIC processor that comm...

rayE

Thanks guy's, this works a treat

Hi, V2.0 I set up a rule as follows. on configFlowSensor do if [%eventvalue%] = 1 // Do something like set a GPIO output endif endon I send the following HTTP request. http://<your esp ip>/control?cmd=event,configFlowSenor=1 With the IF statement i get no response, without the IF statement it will s...

Hi,
I went through the ESP8266 data sheet but cannot find any reference to the ADC input impedance? Looking through some posts on various forums it seems like the impedance is between 10 to 20 megs. So make R1 value high, 220K, it will waste less power from the battery

rayE

Hi, Here is a better calculator that lets you enter one of the resistor values. http://www.ohmslawcalculator.com/voltage-divider-calculator Vin = 4.3V Vout = 1.0V R1=18K (standard value) R2 =5454R For the calibration take a look at the ADC device, Im not sure how the 2 point cal works as iv not trie...

rayE

Hi Olbi,
What firmware version are you using? i take it you had no problems with the esp rebooting?

rayE

On the calc i used Vin max to be 4.3V and Vout to be 1V

rayE

so take a standard value of 10k for R1, use the calculator and R2 is ~3k, http://www.ti.com/download/kbase/volt/volt_div3.htm so double the values to use less current. DO NOT GO OVER 20K for R1, otherwise you will get inaccuracy s on the ADC readings. Also bear in mind that the ADC input impedance w...

rayE

Even /100 would give you a very poor resolution! as i said from my brief experiment when the pulse counter worked it looked to me like the minimum resolution is 1mS. So i would think divide by 1000 BUT the pulse counter looks like it still has a problem? maybe someone else with a frequency generator...

rayE

This is how i do ADC signal conditioning (for a battery) on a PIC, works a treat and very stable.

rayE

The input impedance of the ADC WILL vary during use therefore the potential divider network should be kept to sub 10K levels otherwise the input signal will vary a small amount and not give accurate results.

rayE

I gave the pulse counter a try today. Set up as follows. My setup: v2.0.0-dev12 Device = Pulse Counter I/O = CH5 Type = delta/total/time Mode = Rising Delay = 10s I injected a 3.3V p-p 1Hz signal into the I/O pin. For the first minute or so it seemed to work, the time variable gave an accurate repre...

rayE

Dont you just set up a pulse counter device and set it to be delta/total/time? iv not tried it but im presuming the delta value will be pulses per second?

rayE

CAUTION..............because i have NEVER used the ESP ADC i assumed it's Vin range is 0 to 3.3V, according to this link it is 0 to 1V. Tripple check what it is before working out your potential divider. http://www.esp8266.com/viewtopic.php?f=5&t=5556&sid=a68de43234a8120336a7679c6f2a430c If ...

rayE

Yes, for the charge status, remove LED and wire from the Anode side of LED to a D/I on ESP. I soldered a 5 pin SIL header to the PCB, bent the middle pin 90 degrees and soldered the wire link to the LED from this pin. This way to can unplug the PCB from your main PCB. Regarding the potential divider...

rayE

As a note! i do find the WiKi index page "lacking" in the ability to find specific information. Instead iv resorted to a google on the topic of interest.

But apart from that ESP Easy is SO NICE to use, well done guy's and gals

The answer is READ THE DOCUMENTATION

Code: Select all

on WiFi#WiFiLevel do                                //On the WiFi signal strength event
TaskValueSet 2,2,[WiFi#WiFiLevel]           //Assign the value to field 2 in task 2
endon                                                     //End rule

rayE

I want to retrieve the WiFi level and assign this to one field of a quad dummy device. So i will set up a "sys info" task and un-tick the "send to controller" box. From my basic understanding i will then set up a rule that triggers once the "sys info" event has happened...

My solution to posting data (multiple fields in one go) to thingpeak through the ESP serial port is here.

Dummy quad.png OK figured it out with some tests. I did the following. 1. Flashed V2.0.0 firmware. 2. Set the controller to be Thingspeak. 3. Set a dummy device with a simulated quad_type_sensor, as in the attached screen grab. This now allows me to send parameters through the serial input on the E...

Hi All, A question about the functionality of a dummy device used with the Thingspeak protocol, the dummy device has place for 4 values, each individual value can be assigned using the following code that i send in through the serial port.

rayE

Thanks for the information. I will give it a try today

Ray

rayE

Is this the direction i should be heading?

TaskValueSet Rules Set values on a Dummy Task device TaskValueSet <task nr>,<value nr>,<value/formula>

rayE

I wrote a more detailed post but it seems to have vanished into the ether. A couple of other things i do with the TP board. 1. Remove the LED's as they are a total waste of power. 2. Change the current limit resistor to match the maximum output of your solar panel (see the TP4056 chip data sheet for...

rayE

This is how i have set up Tools - Advanced

rayE

OK, i made some progress on this today and did the following. 1. Flashed ESP Easy onto ESP-12E module. 2. Set all the basic settings to connect to my network. 3. Followed the instructions here to send data to thingspeak http://www.letscontrolit.com/forum/view ... f=4&t=1175 4. Set up a ser2net d...

rayE

Hi,
Thanks for the quick reply. I can tailor the protocol to whatever ser2net wants so that is not a problem. I will look at the ser2net plugin and hopefully get something up and running.

Thanks for the pointer.
