You can also use command topic with the OpenHAB controller which your device subscribes to, this does not require installing MQTT Import plugin. You can post there event names with arguments which can be interpreted as events in the rules. For instance On ctlEvent do If %eventvalue1%=0 //do whatever...

This is electrochemical type of sensor, it reacts to the change of gas concentration in nanoampere current range, so there is a potentiostat circuit which converts current to voltage. Winsen's analog front-end has serial output but there's also 0.4-2V analog output, so you may use ADC input to read ...

Wow, please do not forget about DS3231, it usually comes together with DS1307 and is much much more precise

Maybe I shoud find another solution for my task. You can try this binary as a last resort: https://www.letscontrolit.com/forum/viewtopic.php?p=38093#p38093 Well, with some effort that playground plugin could be adjusted to work with the current ESPEasy sources, but I don't own that type of hardware...

Please take a look at this post: viewtopic.php?f=6&t=6978&p=38864&hilit=ds3231#p38863

There also should be somewhere a link to compiled binary with both plugins added.

Can you make an issue for it on GitHub, or else it is impossible to find back.

RTC memory is definitely Ok as the dummy values are kept, etc. According to two startup logs below, it restores system time after any number of consequent reboots. Different story with deepsleep, it doesn't read timestamp after System#Wake event. NTP was off, so time is just default. 79 : Info : INI...

chemmex

Just recently made a check if the clock can survive reboot and/or deepsleep. Conclusions: system re-reads last timestamp from RTC memory after software and hardware reboot. However, after waking up from deepsleep, no timestamp is read, and hence no system time recovered. Testing was done with manual...

As the author enecbs told me some time ago, P_156 and P_157 can be compiled only against sources prior to 18.10.2018.

We are installing Espeasy-based geiger counters in Belarus where we have twice the trouble: 25% of the territory contaminated by remains of Chernobyl, and a freshly built nuclear power plant which nobody beleives is safe. It is always good to know the truth even if someone goes panic.

chemmex

CAUTION: be aware that the Sonoff 4CH R3 is not safe to wire anything external onto, as the unit is directly connected to mains power, making it potentially very (electrically) dangerous.

In fact, 4CHR3 has a switching power supply inside, so all ESP circuitry is galvanically isolated from mains

chemmex

Can I infer from this, that these .bin's, are intended to run on an ESP32 based platform?

No, that's genuine 2MB ESP8266 module from Espressif

I found that the easiest (in my opinion) way to transfer commands and arguments to the Espeay is to subscribe to the command topic and send there event strings along with numerical arguments. Upon reception they will be treated as events and event values respectively. That said, if I subscribe to %s...

chemmex

According to 802.11n spec, ESP should dynamically adjust TX power based on RX level or RSSI, so we can expect possible heatup in case of poor reception. Just like with mobilephones.

I had to throw away all my modules from doit.am looking exactly like yours. They have different schematics from other modules, I believe that the antenna is completely unmatched. How come they are being sold by a vendor with a name - I have no idea. Mine flashed well too, but the packet loss was ter...

chemmex

You can set the serial port speed in your terminal to 74880 baud to check ESP bootloader debug (which is sd-something stuff). But I suggest you flashing the module with blank file before uploading latest firmware

First of all, there's https in the url, so no chance to send it that way

chemmex

If you set the SSID to a non-existing value, it will first seek for that network and then start an AP after a certain timeout. Alternatively, you can set WiFi passphrase using WifiKey command (or in Config menu) to a value shorter than 8 symbols, in that case the AP will be started immediately

chemmex

You should definitely cut off the copper in front of the antenna area of Wemos at both sides of the PCB. And leave some extra room

chemmex

long story short, mqtt import does not works for HA.

in fact, OpenHAB/HA subscribes to the command topic pretty well, you can pass any string payload and then execute it as event in rules

e.g. payload is relay0

Code: Select all

on relay0 do
    gpio,0,0
endon

chemmex

Only disadvantage is that you need to hook it to a PC.

Sigrok also has Android port, so it can be used with a phone via OTG

chemmex

A question basically to TD-er. What is the current status of data retrieval? Is pulling.bin files from the SPIFFS currently the only way to get saved data?

chemmex

Before assuming it dead you can test the sensitivity with any kind of smoke. The laser can degrade over about a year if constantly on, but I doubt that is your case.

chemmex

Totally agree

chemmex

Any chance to blink the LED faster than once a second?

chemmex

Apart from MQTTImport, normal MQTT subscription works well, too. I am using OpenHAB controller, unit subscribes to %sysname%/# topic. Commands are sent to %sysname%/cmd topic, payload contains event command with arguments. With Node-Red the control function looks like msg.topic = msg.deviceId + &quo...

I have both on the way from AliExpress, don't know which one comes first. As far as realize, the difference isn't big, hardwarewise it's basically the number of LEDs and optics, the rest should be the same. I definitely will ring as soon as one arrives, but I think 30102 should be a priority as 3010...

Tried to make a scan from the phone in tethering (Access Point) mode. It actually would be my primary use of the app, searching for ESPs with those random dhcp addresses in 192.168.43 range. No go though, neither normal scan nor deep. Did you consider using the app that way?

chemmex

I am thinking of making a pulse oximetry plugin for ESPEasy. Did anybody have any experience with this type of sensor?

chemmex

Mikroelektronika makes several modules with electrochemical Spec-Sensors onboard. I believe there should be O3 sensor among them. The circuitry consists of potentiostat and i2c adc, so everything is accessible via i2c.

chemmex

Well, actually "Scan WiFi" uses "WiFiConnect" command to configure node. After running this command application downloads json data and checks if the IP is configured. Since WiFiConnect does not configure device properly, application doesn't add the device to device list. I pres...

1. Does your device provide JSON at http://<ip>/json? 2. Isn't your device protected by admin password? 3. Most likely that your issue related to this EspEasy issue: https://github.com/letscontrolit/ESPEasy/issues/2985 1. Yes 2. No 3. I see nothing common with that issue as the ESPEasy is in AP mod...

Hi, below is my pulse counter plugin screen. My geiger cirquit produce short positive pulses, no debounce, and they just get registered by the plugin.

I think you should check the command reference first to find which commands may work through mqtt subscription. As far as I remember, gpio is not among them. However, you can initiate the event with event command, pass any arguments such as gpio# and state and then use it in rules for activation

chemmex

Here's my voltage detector part, similar to those in Andreas' video. Cuts down at ~2.7V and provides some hysteresis turning on when the bat is charged to at least 3.1V

chemmex

I get similar functionality using ESPEasy with counter plugin and single gpio. Data is uploaded to mqtt broker every minute, then processed in Node-Red and visualised in Grafana.

chemmex

Based on your discharge graph, you are in the upper part of the discharge curve which is very nonlinear. So 50mV drop in this region is basically nothing to worry about, you may then experience weeks at 3.7V without a sign of depletion. In fact, voltage is not a good indicator unless you personally ...

chemmex

I'd use Node-Red to convert JSON data to whatever ESPEasy could accept and pub it back into different topic.

Precise metering has a (high) price. Don't expect a BME280 from Aliexpress (usually a cheap copy of the genuine Bosch sensor) to be as accurate as the Bosch type. I wouldn't be so sure about someone's ability to copy Bosch's MEMS technology. Even if someone in China could mimic it, I don't see a ma...

chemmex

Even better will be using switched charger such as TP5000. Even though it doesn't have MPTT, it can catch low sun condition provided the panel OC voltage is between 5-6V

Also in Timer 2 the publish message comes not through on all nodes:
