Re: Modding external I2C to SONOFF S20

Yes, maybe. But before writing down a statement I have to take in mind, that e.g. AC current can be measured using the hall effect - and galvanically seperated though. We'll see.

Re: Modding external I2C to SONOFF S20

The device on the picture red surrounded, the transformer, is the device for galvanically seperating high and low voltage circuits as it does in every charging device for smartphones e.a. So from the moment of opening the case it was a standard switching power supply for me and therefore a "safe" lo...

Re: Modding external I2C to SONOFF S20

At first, @both: thank you for your hints. You are right, messing around with 230V is not a game. I checked with my multimeter and there is no electrical connection between the mains and the pins. Does anyone have a source where these concerns are coming from? I would be really interested. I could i...

Re: Modding external I2C to SONOFF S20

Hi, the four pins onboard the S20 are directly connected to the ESP8266. So if there would be any connection to LIVE the ESP has to be able to run by 230V - sounds new to me. So I think, there is no connection. But NEVER OPEN THE CASE IF THE S20 IS CONNECTED TO LIVE. But: I will not be responsible f...

Modding external I2C to SONOFF S20

Hi, playing around with the SONOFF S20 I wanted to access I2C on this device. Flashing the S20 with espeasy is a known procedure and widely documented. Ih you disable the serial port of the device in Advanced Settings, you will have access to GPIO 1 and GPIO 3 of the built in ESP. But: To access the...

Re: nodemcu on battery

Hi,

as you can probably see on the pictures, my soldering skills are not the best either. But its possible. At least desoldering the CH340 ground pin is it worth to be done.

And yes, -e +a.

Re: nodemcu on battery

Hi, in the last weeks I tried out some hardware modifications to minimize the power consumption of a Wemos D1 mini (clone from China). At least I was able to reduce the power consumption of the breakout board down to 70µA during deep sleep. All measurements I did refer to a 5V power supply. I starte...

Re: Timer too fast in rules

Yes, I already supposed that. I know that setting up a time depending calculation using a timer event is not the best way. But I am glad to get my hands on an ampere hour meter using the rules. Helps a lot monitoring my batteries. And I am fine, if the correction factor works. Fortunately I do have ...

Timer too fast in rules

Hi, if I'm wrong here with my post, please excuse me. I didn't use the search function into the deep - lack of time. I am building a monitoring system for a set of four lead-acid batteries. The best way to monitor the remainig capacity of these batteries are the amperehours. So I started up with a W...

Re: nodemcu on battery

Hi,

I've just learned, the MCP1703 LDO voltage regulator is definitely the better choice. In comparison to the HT7333 its specs name the half of quiescent current, 2uA instead of 4uA. Thanks for this tip!

Never stop learning!

Hi all, thinking of putting this to the next level. I have some solar panels that, when fully in sunlight, produce 5V. I do have a charger board like the one described above for the battery but as the sunlight drops, the battery is no longer charged. So I was wondering if I could do the following: ...

Re: No Publish after Deep Sleep

Hi,

publishing from deep sleep works for me on a Wemos D1 with git-version mega-2018-05-06 pretty stable.

Only hints: power drain (might be a hardware issue with my step-up) and publishing after wakeup three times.

MPU6050 - GY-521

Hi,

in the Wiki the sensor MPU6050 resp. gy-521 is explicitly listed as suppoerted.

I cannot find it in the device listing of mega-20180421. Am I blind or is the sensor no more supported?

Re: Hidden SSID mega-20180428

Maybe, I'm using DHCP. Due to the fact that I have a fallback WLAN - different IP-range - to guarantee the monitoring its neccessary.

Hi @all

Hi, I am 59 years old and starting fresh into the IoT. Already running is an ESP32 as a Solar Battery-Surveillance and a Clocktimer for the heating of my house. I've found Easy ESP today and I am pretty impressed about the functionality. Thanks a lot at the busy people woho make this project possible.
