UPDATE: My new Hub version 3 is out. Check it out here - ua-cam.com/video/as6laOtSeNY/v-deo.html
I am working on the Hub version 3 and hopefully will have it out in January along with the version 3 of the ULP trigger sensor. I will make them available in the store as soon as they are ready :)
Fantastic project, if you still need a case let me know along with the dimensions of the board ideally a 3d STL file and I can do you one.
I have an old mains adapter case for a wifi repeater that I will design the PCB to fit as I already use it for an MQTT connected display.
Initially, I did the same. I used an enclosure from a battery bank until a viewer sent me a case design. Thanks!
for your HTTP integration, it might be useful if the resource layout is a bit more RESTful, so perhaps under status you could have //status and a GET on that resource would retrieve the status. And perhaps the "/" resource would return all of the ids that can be used in the resource tree. In any case, MQTT is probably much better here. I love seeing more MQTT projects!
I want to know how you connect esp01 to another ESP modul. It's not working for me.
I included the schematic with the source code. It should all be there.
I've been thinking about something like this for a long time. Thank you very much
Your design helped me to solve a subtle problem introduced by a change of Internet provider in my community. The new provider provided an Eero mesh router which could not adapt to a specific channel required for espnow. I used the D1 mini as a hub and a esp01 for the espnow receiver fixed on a specific channel. The serial insterface on the esp01 works well bridging the espnow message to the D1 on wifi. Thanks for the ideas!
Can you please make a video on how to make this web page ?
Subbed, slick work!
Thank You
Would buy one if you shipped to France :)
I am exploring international shipping but they are pricey!
Can you share the code behind the gateway & receiver instead of bin files?

@@MrDIYca Thank you
I am going to order one, then I will make a case for it! Nice job
That is awesome. Looking forward to it!
Can i build a messenger like whatsApp with this?
That is a really nice design for an ESPNOW hub, I would buy one if it eould ship to the netherlands 👍
Thanks! I will look into adding international shipping :)
@@MrDIYca Hi there, what a great project, exactly what I was looking for! Will you get new stock in and did you sort out international shipping?
@@martinlenke thanks! Hub ver2 is sold out. But I am planning to have Hub ver3 out in ~January. I haven't looked into international shipping yet but I should soon. Are you in Europe as well?
Awesome video ! What a great project !
This can be done with a single ESP32.
It can also be done with a single ESP8266, but it's not really worth it.
@@MrDIYca It cannot be done reliably with an 8266. I am referring to simultaneous communications, not alternating.
Very interesting, I like it.
Thanks
You can use broadcast to send scan command to slaves so the receivers can identify them selfs to the hub and in the same time add the hub mac address as a peer to send Data
You can but the sensors are battery powered and their radio is 99% of the time off.
Great Project, I love it!
Thank you! Cheers!
do you have a build video for this, how are you doing the comms between the 2 devices ?, really missing this vital build walkthrough
the schematic is in the video at 1:16
@@MrDIYca hahah yes i see that, it was more that a video walk through of comms between the 2 devices would have a good video, to see how youve done that without me having to download the code and figure it
Hi, Thanks for this video.
Why 2 different esp on this board ?
Do you know of a reliable way to do it with just one? I couldn't find any
@@MrDIYca no I mean why 2 different form factor (esp01 and shielded esp8266) 😉
You are getting ahead of me :) this will be answered in the Hub3!
ship international?
Not at the moment, but I will look into that option.
@@MrDIYca tag me when you do
any time soon to have this back in stocks, so we can buy it.
Not until the new year sadly
@@MrDIYca yes thx! Will wait for that!
I also want to buy this!
@@cmorda11 Sorry, it is sold out. I am working on version 3 and should have it out sometime in January - maybe check back then :)
