Cache controller roadmap

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?

Re: Dust Sensor SDS011 Reading too low

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.

Re: Controlling DeepSleep over MQTT

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 + "/cm...

Re: MAX30100/30102 heartbeat and oxygenation sensor

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...

Re: Android application

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?

MAX30100/30102 heartbeat and oxygenation sensor

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

Re: Gases Sensors

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.

Re: Android application

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 press "Scan WiFi", I get...

Re: Android application

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...

Re: Geiger counter settings

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.

Re: ESP Easy Mega MQTT issues

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

Re: Solar Power Supply

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

Re: Geiger counter settings

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.

Re: Battery goes down WAY too fast on ESP

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 ...

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

Re: Temperature sensors - which are most precise?

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...

Re: Solar Power Supply

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
