Following on from the forum post here ESP8266 Wifi Developments . This is a brief guide on how to use the Adafruit ESP8266 Huzzah WIFI breakout module with an EmonTx v3 to make a simple WIFI enabled energy monitor that posts to a remote emoncms server such as emoncms.org . Note: this is an ongoing de…

Hi Paul, thank you for the suggestion! Now works properly. So, if someone will have the same issue, the solution is to connect the RX pin of the emontx with the RX pin of the nodemcu (or whatever). Le me say that this is not so intuitive! :slight_smile:

Hi, I used arduino ide to load emonesp firmware and data in several ESP-07 and I couldn’t make them work properly. When I loaded firmware and data to ESP-12E everything works as expected. Somewhere in the installation instruction guide is mentioned that should be used ESP-12E and I can confirm an…

Cracked it last night, now I have the power sorted it the ESP-01 can read the values from the EmonTX. Need to get it setup in place and do some more tests. As mentioned the current incarnation of the EspEmon firmware is ok to fit in 512MB flash. I am not totally convinced OTA will work but that is …

I don’t think you’ll get OTA working on the 01. For as much as a beer you could be buying these instead - http://www.banggood.com/D1-Mini-NodeMcu-Lua-WIFI-ESP8266-Development-Board-p-1044858.html?utm_source=google&utm_medium=cpc&utm_campaign=Celc-ad-rm-DM-D1MINI&utm_content=gary&utm_design=27&gclid…

For information here is how you wire up the ESP-01; [image] and a pic of my setup; [image] I have also raised PR #8 with the changes I needed to make, just really adding the ESP-01 as a board for the project. I am seeing an issue where it works for a while but then starts reporting key ‘1’ wi…

Nice! I’ll get the pr merged to allow compiling for 01 using platformio :thumbsup: There is a big update to emonesp in the mqtt branch that I’ve been working on that is ready to be marged into master branch very soon. As the name suggests mqtt support has been added as well as captive wifi ap porta…

Is there any chance the EMONTX sketch can be modified to provide a current AC voltage output so the AC adapter can be calibrated? Also I think there is an error around the ct2 calculation area as the next ct3 section references ct2 rather than ct3

Is was going to get on to this after the EmonTx OTA was done, I also wanted the temp stuff as well. In fact, @glyn.hudson , is there any reason we could not merge the EmonESP support in to the other EmonTx firmwares and just protect it with a #define or even better add a run time switch, sent over t…

[image] kevin: Is there any chance the EMONTX sketch can be modified to provide a current AC voltage output so the AC adapter can be calibrated? You mean the present (= at this instant) a.c. voltage? - The default sketch does. If yours doesn’t, it’s easy to extract it as it is already calcula…

Yes, the present AC voltage appears absent in the ESP serial only sketch. That and the 1-wire missing means I’ve changed one of the standard sketches for now. The ESP serial only sketch seems based around the continuous sampling firmware which I was hoping to upgrade to for better accuracy.
