Re: MCP23017

I have seen in the source code that the pull-up resistors are enabled by default if a GPIO is configured as an input (if I checked correctly). Is it possible to implement an improvement to configure the input pull-up in the configuration view of the input (enable or disable if needed)? Just like an ...

PCA9685 PWM feature request: Phase shift and complete on/off

Hi all, i would like to request the following if it is possible: - add a phase shift (by setting the correct registers) for the pwm channels - turn on or off a channel completely - change frequency settings This would be very useful for my application! All of this features are already included in th...

Re: Dynamic SleepMode

Hi there,

Is it also possible to execute the deep sleep command with the FHEM Plugin? Which modifications would be needed to be able to do so?

Re: (Re-)Flash ESP8266 with dedicated ESP8266 using Ser2Net

Unfortunately I don't have a laptop. So I thought it might be easy to connect a "network based serial port" to the device which should be flashed. In case of a lost netwok connection you are right. But this szenario is just one additional option to flash an ESP8266, it is not the only poss...

(Re-)Flash ESP8266 with dedicated ESP8266 using Ser2Net

Hi All, For some cases (especially when playing with rules) I had the problem that I could not get any wireless access to the ESP8266 anymore. I needed to unmount the ESP from the location to be able to put it close to the PC again and re-flash or (factory-)reset it via the serial port. My idea is n...

Rules with combining logic

Hi all, I am planning to use a SONOFF with a BH1750 luminosity sensor to control a secondary lamp in a bath room. The ESP will be used without an external controller but with the internal rules. What I understand is the following example rule: On brightness#lux do if [brighness#lux]>1 // Master ligh...

Combine Deep Sleep and latching output with I2C port expander and rules

Hi all, I am thinking about a feature which would help me a lot saving some energy but still reacting on sensor signals. The idea is to use a DHT22 as a humidity sensor and switching a fan on in case that the humidity reaches a certain level. Additionally I would like to set the ESP into deep sleep ...

Hi all, I am currently setting up a new PCB for heating automatisation using the ESP8266 with ESPEasy and FHEM and i am running out of IOs for the ESP12-E board.

Re: ESP8266-12 deep sleep mode freezes chip

I don't have a schematic right now. But you can test the following: Check the voltage level / pull up & pull down resistors of GPIO0 (high), GPIO2 (high) and GPIO15 (low) Check that you have a 12k between Reset and VDD Check that you have a 100nF between Reset and GND Check that you have a 470R ...

Re: [Solved] Factory Reset without WiFi

I moved to a raspbian distribution (Raspberry Pi) which had python already installed to get rid of installing it on windows :-). This made it a little easier. But it should work the same way (after installing python) on windows ;)

I already tried re-flashing the firmware ut it loads the old config being stored in the chip (I rarely can ping the chip for some ms within some minutes) Currently I try to...

Re: ESP8266-12 deep sleep mode freezes chip

Dear all, I finally found the root cause... It is very easy if you know :lol: . In case you do a proper reset, the ESP8266 needs some time to clear the internal registers. If you connect GPIO16 directly to the reset pin, it will try to do the reset but the reset itself will release the reset. If the...

Re: Feature Request: set I/O via MQTT / disable deep sleep

So what I read about the I2C Port Expander is that they both need very low current (~10µA) in idle.

Still it would be very useful to change the settings via MQTT. Then the device would also receive the command in real time if desired and go back into deep sleep it nobody is awake :-)

Re: Feature Request: set I/O via MQTT / disable deep sleep

I have already found some information concerning "retained messages". These messages will be send to the ESP8266 directly after he subscribed. So the I/O can be set by this very easy (I will need to verify it and keep you upp to date!) If settings could be modified by MQTT messages (especi...

Hi all, i was thinking about a feature that the ESP Easy is missing and that i would need for a project. If you just have sensors, it is no problem to set the chip into deep sleep. In case you need to use a pin as an output, the problem is that you cannot disable deep sleep in any way except restart...
