Re: Joystick - buggy - rules??

Thanks for your response. Yes I know I could change the numerical range by using the formula (which I've done with my soil moisture sensor). I know roughly what I want to do, the problem is getting my head around how to use "rules" to achieve it. Really sorry I created some concern with th...

Joystick - buggy - rules??

Hi, I'm planning on starting a WiFi-based buggy project (with my students) using an on-board Wemos D1 Mini to drive two motors using PWM from Node-RED. I plan to use a dual axis joystick (as the control box) where the analog values are sent to two ESP8266s and then via MQTT to Node-RED. My question ...

GROVE GPS module with SIM28

Hi, Has anyone managed to connect a Grove GPS module to a Wemos D1 Mini ? The one I have uses the SIM28 GPS processing chip. I believe the module uses a serial communication - but it could be I2C. Product reference is: 113020003 from Seed Studio. Any information/advice on connections and how to extr...

Re: Soil moisture

Here's a link to a PDF instruction sheet that I made for the IoT Club where I work as a tutor.
It covers the practical steps involved in setting up the mositure sensor.

Re: Soil moisture

Hi, I use the first version of the mositure sensor. I don't use the digital output. I use the voltage or analogue output. The voltage output connects to the analogue input on an ESP8266 (Wemos D1 Mini). I've mounted the Wemos D1 Mini on a small breadboard and routed the +3v3 for the moisture sensor ...

HX711 device interface

Just wondering if the HX711 device interface was ever added to a recent ESP Easy release ???

I've just ordered a Load Cell and HX711 interface card and was wondering the best way to control it from ESP Easy.

Any help/guidance/advice would be appreciated.

Re: no wifi (esp_0) after flash on S20

My suggestion is to flash it using the bin file for ESP8285 (sorry 'bout that typo) since the ESP8285 is equal to the ESP8266 except that the 8285 has 1MB built in mem. The newer Sonoff seems to need other flash settings active, which the bin file for ESP8285 seems to have (please correct me if I'm...

You could try flashing it using 8255. The markings on the chip says it's an ESP8266. What are you suggesting? 1. Try flashing it with firmware for 8255, or 2. Flashing with the ESP8255 flasher tool Reading all the above messages it sound as if lots of people are having this problem. My S20s are for...

Hi, Thanks for your swift response. I assume the comms port is situated on the front of the SMART meter and is just a simple infra-red link ??

So this means my ESP8266 can only "talk" to ONE OpenHAB MQTT server?

Was there a reason to limit the number to one?

OpenHAB MQTT option missing

Hi to all,
I've just tried updating some of my ESP8266-based nodes to V2.0.0-dev7 and discovered that the OpenHAB MQTT option is missing in the Controllers menu.

I've checked all the versions from V2.0.0-dev4 and they all seem to have OpenHAB missing.
