Brilliant idea to deploy mosfet/relay instead of deepsleep. Wonderful. Thank you so much!

This was an interesting concept. The ESP8266 really got me interested in programmable microcontrollers again. Having such easy wifi connectivity is awesome.

Thanks for all your videos, Andreas! They've been very helpful to help me understand what can be done with ESP8266 and Arduino in general.

I really enjoy watching your channel. I think it has something to do with the way you explain things. Please keep the videos coming, as long as you enjoy making them. Cheers!

Thank you for your detailed and clear explanations. Your topics always seem to be interesting and relevant. Well done sir.

Hey Andreas, great job. Thank you for putting so much effort in making these videos!

Can’t stop myself watching your channel this morning - it gives so much ideas! Thanks a lot for this.

this will help a lot of people. I really enjoy your low power techniques videos

Thank you so much Andreas for all these videos, your research and advice is so helpful. Its such a good idea to use a mechanical switch to keep the current consumption down. Hope one day we are able to crack the esp8266 ssl problem

Keep up the great videos. You've taught me so much as I venture into IOT.

Thanks for all the great videos. I learn lots and get inspired for new projects.

I always learn something new when watching your videos. Nice idea about the long battery life. I need to look into IFTTT as I have not used this before. Hope the Pizza was nice. Best wishes Arthur

Hi Andreas, I love this channel! Thanks for all you do. ☺

Excellent and informative channel. Always look forward to and enjoy each video. Thank you!

hello from Sydney. keep bringing the small projects in the esp8266. Ive only just stumble soon the esp8266 after watching the new wifi jammers using this board. then after a quick UKposts search on the nodemcu I found your channel a diamond in the rough, great content. it's a pitty the smaller new channels don't get more exposure to new veiwers. awesome work :)

This is one of my favorite youtube channels, although I'm a Spanish, I like your accent. Thanks you so much for you videos. I'm so glad to recommend your channel.

Brilliant, elegant simplicity. I have a sensor gizmo that uses an ESP8266 to take readings every 30 minutes. I use deep sleep (timing isn't critical), a LiPo battery and a solar panel. To move this out of the sunshine, I'm thinking I could use a clock with alarm function to trip the relay.

Perfect for an alarm for door left open on the old refrigerator in my garage. Thanks, and Happy Sechseläuten!

We have a side gate at our house that the kids are forever leaving open, for ages I've wanted to fit some kind of sensor to warn us when it's been left open, but without power I was stuck how to solve it. With the idea in this video to use a relay to let the processor control when it switches off is just what I need, Thanks Andreas.

Excellent practical use for these esp chips

Andreas, your stuff is always good. Thank you.

Great idea Mr. Spiess

What a wonderful solution, thanks for the well thought out videos and explanations.

I really enjoy watching your videos. Thank you.

Very interesting video and plenty of food for thought. Thanks for the inspiration Andreas.

really like this unique power saving strategy

Wow 😲 loved the concept and execution

Greetings from Las Vegas Nevada. Thanks for excellent tutorials.

I've had an ESP8266 in my postal mailbox for sometime. It uses the same concept. When the mailman opens the box, it powers up the ESP8266 and keeps the power on until done sending a message. I've enjoyed your videos and they have inspired me to do more projects.

Great video. Very informative. Thanks Andreas.

I like your methods Herr Spiess. Enjoyed the video.

Nice work. Always an educational experience.

thanks a lot for your work

How did I not think of this? It's a brilliant method.

This is my comment to help your channel. Keep doing such a good stuff. Greetings from Poland!

Another good project. Keep up the great work. Thanks.

Keep up the good work! Love to watch your channel!

Very cool idea with the relais!

Really cool stuff! I'm going to use this to make a mailbox notifier! 👍🏻🙂

Watched many of your videos and learned alot! Big thanks and keep making these videos! :)

Thank you for doing unusual things with the 8266. There are thousands of videos of people doing all the same thing. Good job doing something different.

Hi Andres, wonderfull concept! I can forsee several projects with this idea! thanks.

Blessed to have ppl like you... Great Sharing (y)

The relay is a brilliant idea.

This is really interesting, thanks for posting

Thank you for yet another great video.

Andreas, very clever technique, I liked it :)

This is my comment to help your channel. Keep doing such a good stuff. Greetings from The Netherlands !

Liked and commented, because this channel is absolutely awesome! Thanks for your great videos.

Hi, very interesting how to put esp info "sleep". Thank you for your video.

Great stuff!!! Thanks Andreas!

Been following your channel for a while. Thanks for the info!

I really enjoy your videos - thanks

Very nice video, and I'm so glad that you did not go with the relay solution... waaaaay too much power required, even if only for the short time while the microcontroller runs. I was looking for a latching "soft power on" circuit that does not draw any power when off and haven't found one yet, but they must exist... at least I hope so. Cheers,

As usual, an excellent video, keep up the good work.

its a great idea . man you keep making things that i keep wanting to try .. but need more hours in the day .

I have used a similar concept for my mailbox but instead of just a p-channel mosfet I also added an ATtiny85. It waits in deep sleep for an external interrupt (or two) and powers the ESP8266. When the ESP is done is signals the ATtiny to go into deep sleep. In deep sleep th ATtiny and mosfet together use less than 1uA. With the ATtiny you can have more than one interrupt like for on and off buttons. So the same circuit can be used to trigger two separate functions.

very cool concept! thank you!

success to this very informative channel!

Great video, thanks for the content.

You have great electronic material

Great information. Thank you.

Nice video Andreas.

amzing device the esp8266, arduino killer! thanks for your generosity Andreas!

Great channel, I follow all your hacks, they are great and help me a lot. Claudio from Brazil.

Keep doing such a good stuff. Greetings from Argentina!

I like your videos and pizza! More relevant to this video, a CMOS logic chip could operate at a very low power level until it wakes up with the press of a momentary button, then enable/supply power for a desired time, then sleep/deactivate your circuit. I used a 9V battery in such a CMOS logic circuit for 30 years and it still worked, although it was in stand by almost the entire time.

Great project, thanks!

Thanks for doing this channel!👍👍

Comments from Victoria BC Canada, because you asked so nicely.

Again a great video! Thanks from Bavaria

so many great ideas. you rock!

Have to look into those 8285s, never heard of them.Thx! Liked and commented!

Nice work!

There's no problem LIKE-ing. So, here's my contribution. Woohoo! Your videos always rock!

Hi Andreas. I am a new subscriber. What great tutorials!

Thx for the valuables informations !

Thanks Keep up the good work!! Very interesting.

Thank u so much for doing this. Liked and subscribed.

great project

great project!

great work, awesome idea !!!

In the case where a voltage regulator is used, a model with an enable (CE) pin is advantageous. The power latch GPIO can be connected to the CE instead of an additional mosfet.

My favourite electronics channel

I also like your channel! ;-) It is more and more interesting with each new episode ;) Greets from Poland!

Comment for help.. Thank you for making these videos, Mr. Spiess :)

This was interesting. Than you for producing it.

Great video as always

I like your projects!

Great video! Keep them comming!

nice idea with the relais/MOSFET

Thanks a lot for your great video

Now that dash buttons aren't sold anymore this is a good tool for my needs

this is amazing. thank you

Very interesting topics, thanks a lot!!!

Another great video, Andreas....I am a subscriber very happy.

I've been saving this video for awhile and finally have used for my mailbox notification setup! I am using with a WeMos D1 Mini because I will need an external antenna. However, I found that while the mosfet (NDP6020P) would turn the WeMos off, that it continued to draw current (not sure how much). The only thing that stopped it was removing the battery or pressing the WeMos reset button. My solution was to use ESP.restart(); in lieu of digitalWrite(4, HIGH) to "turn off" the mosfet. Just thought I'd share. Thank you Andreas.

This is my comment to help your channel. I rarely do not watch your channel. T hope this help to keep the lights on. Greetings from South Africa.

Great work

Great great great work Andreas! Appreciate all the hard work you put to make this work.I have been behind such a long term power solution for my new project. Your ideas will be a breakthrough for my project. By the way, can you share the code and schematics.pls?
