So you need your ESP32 (or other Internet-connected system) to "phone home" and let you know there is a problem? This simple method of using WhatsApp may be the answer for you.
For hobbyists, it is ridiculously inexpensive ($4 per YEAR) and easy to implement.
For businesses, or those with a more complex required, there are very affordable plans to allow messaging any phone and receiving replies, or button clicks and much more!
I've included some simple (albeit not secure, nor encrypted) code as an example but we'll update this as part of the ESP32 HTML series of videos I'm doing.

I have heard the expression "and Bob's your uncle" before but never knew its origins. I asked Alexa and she informed me it has something to do with one of your Prime ministers, Lord Salisbury, that gave a plush appointment to one of his nephews. Thanks Ralph for another informative video.
@monoamiga Рік тому
I needed that knowledge! ;) Thanks!
@RalphBacon Рік тому
I never knew the source of that expression (nor do I remember saying it in this video, it's just part of UK everyday speech, I suppose) but always good to know!
@willofirony Рік тому
I like the thought of conversations, i.e. a two way link. Then, given the software to respond to an incoming message at the ESP32 end, could switch your heating off for you, even if you were down at B&Q when you received the warning. As to cost, in your heating example, the link could pay for itself and reducing your carbon footprint is for free! Well done you, Ralph.
@RalphBacon Рік тому
Your suggestion sounds good, Michael. I'm sure there are countless ways this could be used to good effect.

Cool video! Just one remark: %20 is not 'twenty'. Twenty is %14. %20 is 'two-zero' since it's not decimal.
@RalphBacon Рік тому
Well, strictly speaking yes. In the same way we should not say 1 point seventy-five for 1.75 when it is one point seven five, but in everyday colloquial speak I think it's OK.
@briansmith7015 Рік тому
Hi Ralph. I use a sim800 board with a nano and a 1p mobile sim (texts are 1 p each). The big advantage is sms's go straight to phone where as messenger services seem to go to sleep if the phone is left motionless for a while. I've migrated the whole lot onto a pi 4 and node red but the basics are simple. Luv the videos, thanks. B.
@RalphBacon Рік тому
Sounds like a good alternative method, Brian. But I get WhatsApp messages regardless of what my phone does (it keeps running in the background, I'm assuming). Anyway, as long as we have some sort of messaging system running it's all good!

Think I am going to have to make a couple of panic buttons for my elderly in-laws. Hopefully works with 8266 so I can keep small add a covered toggle switch, Cr2032 battery and you have a pocketable device for those help I've fallen and can't get up moments. Keep up the great content, I get a lot of great Ideas from your channel.
@RalphBacon Рік тому
I know that the ESP32 is a bit too heavy on sleep current for a CR2032 battery so the ESP8266 may fare better. Or check out the ESP32 single-core alternatives(which are replacements for the ESP8266, says Espressif) which might have lower currents. Or, do what I do with my Storage Bin Lid devices and have the current totally switched off by using a SI4599 dual MOSFET. The button is then used to switch it all on, send the message and auto-switches off when done.
@garrett798 Рік тому
@@RalphBacon was actually planning on the device activates on toggle switch on and sends message and perhaps lights led when sent. Not as elegant as the MOSFET but was just going to have returning the toggle switch to turn off. By the way in laws are in Heidelberg just a bit from Stuttgart.

Hi, thanks for the video! Is it possible to use an ethernet shield instead of wifi? Can you do a video with an ethernet board ? Thanks a lot
@RalphBacon Рік тому
You can certainly use an Ethernet shield for an Arduino UNO (and I've done video #74 on that ukposts.info/have/v-deo/fmKeeqKEjbCJkYE.html ) but you can't (easily) plug in that shield to an ESP32.

@scottstevens7569 Рік тому
Great info and opens ideas for sure. :) I use a tablet and phone with no# to communicate with esps, over wifi, so likely the apps signal is over phone provider rather than wifi internet.?
@scottstevens7569 Рік тому
Seems Telegram is worth looking into.😀
@RalphBacon Рік тому
Well, the signal to request the WhatsApp message is sent via a standard URL (so Wi-Fi plus Internet) but the WhatsApp message itself is sent to the phone via the the Internet (but still [optionally] using the Internet). My mum's tablet works like this, no SIM required.
@darktherapy Рік тому
I’d love to see this as an OctoPrint plug-in to notify me of finished prints or print failures etc.
@RalphBacon Рік тому
That would be cool! Also Prusa-Link is now being developed (it now allows transfer of g-code to Prusa printer over WiFi or Ethernet) so a "run this command when finished" would be great. I might suggest it to them (and take the credit 😲)
@egonsvensson2728 Рік тому
Hello Ralph! I use IFTTT for the same type of applications. They have loads of different applets and services depending on what you want to do. You can create 5 applets for free without paying a cent. The applets sends me a mail with text I choose if the burglar alarm goes off and for when the postbox is opened, for example. It sends out mails instantly and works flawlessly. :)
@RalphBacon Рік тому
IFTTT (If This Then That) is a great system, Egon, and I've played with it. But this is just a simple bolt-on standalone service that I'm bringing to everyone's attention.

Hi..excelent video..thanks so much.... However..I can not find the 4 euros/year offer...do you now if it's gone? (sorry..I know this is not your bussiness..but I hoped you could help) thank you..
@RalphBacon Рік тому
Let me check... hmmm, that's strange. There is now no mention of any fee whatsoever for the CallMeBot service, so maybe, just maybe, he raised enough money and now provides the service completely free, like he did when I first started using it. Failing that, you could contact him 🤷♂️ if you need to be absolutely sure.
@WagonLoads 11 місяців тому
Could you please make a video to address all of the problems I list below? I have been designing PCBs in KiCad for a couple years. Nothing produced yet... because I hit a roadblock at the very fundamental level.. esp modules like (esp12F, esp32s, esp32-S3-1U) and others need "Strapping resistors". one example says to put strapping resistors on pins that are not listed in the datasheet pinout.. also, the above esp32 do not all have GPIO21 and GPIO22 used for i2c.. I heard that you can assign i2c to almost any pin on a esp32.. but I'm not sure if any of the above have pins forbidden to use for i2c. It would be nice if there was a master look-up table for strapping resistor pins.. and i2c pins on devices that don't have GPIO21/22 Last question is on footprints Some parts I have no clue what size to use... Like the Stemma QT connector
@RalphBacon 11 місяців тому
I hear your frustration and pain, but that brick wall in front of you is, in fact, just made of sand and can be easily knocked down. When you refer to "esp modules... like esp32s..." are you referring to the actual dev module boards (typically look like this: s.click.aliexpress.com/e/_DCC19nj ) that I often show in my projects? If so, you don't need any extra resistors but you do have to be aware of which pins are strapping pins. This is partially documented here bit.ly/431GQO1 and I notice that he has updated his information after my rant that keeping GPIO 2 high at boot meant that I could not upload code! How annoying! (I might have said it more in the vernacular than that at the time). My updated "Which ESP32 pins to use" can be found here: github.com/RalphBacon/260-ESP32-Web-Pages-Part-2 but also look at the RandomNerds page too as that gets updated too. I can't believe you're using "bare" ESP32 WROOM or WROVER modules like this bit.ly/3pNP668 as my question would be, why? Let me know!

@wolfberrinhos7068 Рік тому
@@Mr.Leeroy It is a solution, but it is a lot more expensive, even using a prepaid SIM, it is necessary to recharge it times to times to keep it active. It Costs a lot more that 4$ per year. I' m looking for something like an free/cheap SMS gateway. I` ve found some but not at this price.
@RalphBacon Рік тому
Not that I know of - not free (almost) anyway. But as Leeroy mentions you can easily build a GSM module and get a SIM card for messaging that _does not expire_ at the end of a period.

@mahudson3547 Рік тому
Good stuff! I have just been wrestling with https to post data from an esp8266. Easy if you don't encrypt it. But a challenge otherwise. Settled for fingerprint for now but the idea of it expiring is a pain. Really look forward to how you resolve it (you will, won't you??!!)
@RalphBacon Рік тому
You can always use encrypted https but "insecure" which means the server's certificate isn't checked (mostly good enough for IoT type stuff). I'll be talking more about this in a future video (that HTML Part 4 I mentioned).
@AleksandrIvin Рік тому
Nice video. Would you consider to use Telegram?
@geoffw.5003 Рік тому
Agree with you, using Telegram for this type of thing is a much better solution. No need to mess about with a man in the middle site or the hassle/risk of having to pay a yearly sub. Also at a quick glance, I dont think callmebot allows for msgs back to control the ESP32. If you use Telegram you can send control msgs back in the other direction
@Leif_YT Рік тому
I would also recommend Telegram. Used it for many projects and its very solid, official API, good libraries and no fees.
