The 'example' is very supportive for making a setup incl. software.
Like Arduino ESPEasy offers PWM as candidate to generate pseudo-AC.
Also describing setups for multiple sensors and how to calibrate.

Found some more manufacturer's information describing the sensor including example How to read the sensor . The example also discusses the aspect of 'mutual effects' between sensors. Cannot (yet) find how the 'managing' Soil Moisture/Temperature Station functionally deals with multiple sensors, but ...

Solar Power Supply unavoidably applies solar panels. In my experimental setup obviously not using the most expensive types. After 3 years of outdoor operation the effects from environment well visible as 'milky' shading (on the 2 panels on the bigger electronics box). Still significant output, but h...

TDer, Indeed life of the thermo-sensor will become much longer if their cover is really thick and very water-resisting: have been thinking for next batch of DS18B20s-in-steel-holder to put each DS18B20 in an extra capsule and fill that capsule with silicon paste or similar emulsion. The filling of t...

For meteo/agrotechnic it is also interesting to measure the temperature and humidity in-soil/underground. Davis has very nice humidity sensor and temperature-sensor , but cost is reason to look for alternatives. In my setups I apply SHT1x to measure Temperature &Humidity in/on the top-soil, and ...

Have tried the flashing-software with another PC(= laptop-workstation) linked to the ESP8266_WEMOS 'at outdoor-location', but results were mixed and not steady: bad recognition of the USB-port. Pragmatically solved: ESP8266_WEMOS taken from the outdoor setup, flashed at the indoor desktop-PC and re-...

Replaced the WEMOS_PCB for a 'fresh' copy: if during the experiments with DS18B20s would have 'fried' pinD5, now another chance. New WEMOS with 1*SHT15 and 1*PCF8591: all happily report 'meaningful' values. Also reconnected the 4*DS18B20s, but less luck. 3V3 Power available from the WEMOS_PCB => 3.2...

Ton_vN

Because for long time the setup has worked without problems, have impression that present problems not caused by component-selection. Also last week have seen a short 'revival' for all DS18B20s. Perhaps biased, but considering power supply and/or wiring as more likely cause. ;) Measuring = knowing T...

Ton_vN

Addition to previous message. Why 2k2Ohm as pull-up for the 5*DS18B20 (and planned 6*)? Recommended/'usual' pull-up resistor for 1*DS18B20 is 4k7Ohm. Multiple setup of DS18B20 needs (slightly) more power. Present 2m of cable is not much, but operation at longer cable may benefit by more current (as...

Ath (and ThomasB), After copying FlashESP8266.exe into the bin-folder indeed the whole list of files can be shown when running FlashESP8266.exe from that location. But that is not as the ESPEasy-package is coming, and nowhere an instruction to make that move. Anyway, will try to test this week on an...

Ton_vN

TD-er Thanks for this really quick&easy solution! Indoor 'bricked' WEMOS_Pro now revived, and (as check) another WEMOS_Pro updated: both to [ESP8266 ... Normal ... 4M1M]. If tomorrow a dry period, then also chance to revive the outdoor 'bricked' WEMOS_Pro, trying laptop as testvehicle with all f...

Ton_vN

The bin file MUST be installed in the sub folder named bin. If not there the file will not be found.

Those conditions met, but no files showing for selection ...........

Ton_vN

That all flashers at this PC went on strike was unexpected surprise, because never seen before. Perhaps also worthwile to install&try those flashers & files on a laptop, as 'different PC'. After indoor-test, then ;-) on a dry day I might try to reflash that 'bricked' ESP-in-the-garden at loc...

Ton_vN

Have used the bin-file (not the compressed file): does that make any difference, except time required? In hindsight , was application of the 4M1M-fileversion appropriate? Because of the text for OTA telling that only 1Mb allowed for OTA. Perhaps also been to eager to see result, and calling too earl...

;) Quiet weekend, decided to use it to prepare for the winter-season ..... One planned activity: update of ESPEasy-firmware for my ESP8266/WEMOS_miniPro's from mega-20200310 to latest version [ESP8266 ... normal ... 4M1M]. One reason = get access to extended settings for PCF8591 . Never used OTA, bu...

Ton_vN

That the Ozone-sensor ZE25-O3 has similarity to CO2-sensor MHZ19 is not really surprising, because as alternative A13-configuration they offer a version with MHZ19B-sensor: then intentional commonality of interfacing is very useful/economic.

Ton_vN

Indeed, booster's coil may induce interference into the surrounding wiring. The setup for my soil-sensors (and planned wetness-indicator(s)) has 3 control & junction boxes: - the bigger top box houses the ESP8266 and all related power supply eqpt, and acts as main Junction Box. Plenty of crisscr...

Frequent drop-out of the WEMOS with it's 5*DS18B20+1*SHT15 causes head-scratching. Apparently due to aspect of power supply. Connection of a 230V-PS is a pragmatic, but undesirable solution. Emperically found that the output voltage from the TP_4056-controller is often (too) low for WEMOS+Sensors. N...

Ton_vN

TDer ;-) DIY-assembly & -application remains a headache with these sensors due to the aspects of aging & calibration. The views in the previous messages more or less confirm my idea ( in that perspective ) that the lease-approach by AQICN.org may have some merit. They deliver a complete pack...

Being interested in sensing for air quality, recently found at the website https://aqicn.org/ under title Gaia-sensors this ozone-sensor: https://aqicn.org/air/view/products/specs/ze25-o3-ozone-module.pdf All sensors applied in these Gaia-sensors seem of a category 'available & manageable for DI...

Sometimes it takes some time before an answer is appearing ......

This message on setting of timing for PCF8591 might explain why my earlier experiment was not successful.
Have to retry the application of PCF8591 with that setting changed.

All other functions of the ESP/WeMOS without any problem. ESP is in a (plastic) box just below the (plastic) box with dual counters: cable-length between S0-interface and ESP is 30cm at most. ;-) Even a shielded cable, because the shield is the common ground for both counters. Checked the circuit fo...

Ton_vN

Just a remark for 'relative' perspective. In this thread much emphasis on 'measurement at same time', but for 1 ESP with a chain of sensors like DS18B20 with a common, 'very narrow' interface that is principally impossible. Perhaps a common trigger to the sensors, but at least the read-out always i...

Ton_vN

@rron You are using 1 ESP in combination with Domoticz, and try to squeeze much work into the ESP. Just wondering why not ESP act just as frontend, and let Domoticz do the more complicated jobs. Have myself realised that already a few times: - array of soil-thermosensors of 4*DS18B20 + 1*SHT15 - arr...

T&H-sensors for soil measurements with long endurance & good quality are not cheap. The simple moisture sensors with fork or pen have no quality in data, but may be useful to generate a very rough indication and for thresholding aimed at a alert. The downside for the very simple resistive mo...

@Davidjohn My setup is powered by 2 Panels of 5W-power. Power from the panels to the TP_4056-controller is not the problem, but the autostart of the WEMOS once sufficient power is coming from the TP_4056-controller. Addition December 2020 ~ January 2021: The statement 'not a problem' in the above li...

At this moment (October, 16th) sunny day, but obviously the sun is not really strong anymore. See flashing LED on TP_4056 as related indication of weak input. Connection of powerpack obviously is an escape-route, although demonstrated to bridge just a few darker days with the load in my configuratio...

;-) Be aware of the characteristics of the I2C-interface as applied by the BME280! Also this interface is not intended to have long cabling. If using the 3.3V from WEMOS to power the BME280, therefore cable length should not be exaggerated. Your cable length of 2.5m probably can be handled, but some...

@TDer 'Softener' seems the word you look for.

@TDer Your argument is exactly the reason that in my setup - the PCF8591 is powered by the Solar Power Supply at approx. 4VDC (allowable = 3.3V ~5V) which is also reference for the onboard devices for CH0, CH1 and CH3. - the Rain-sensor interface is powered from the WEMOS' stabilised VCC at 3.3VDC: ...

Main target is to support battery powered nodes and to cover areas without WiFi coverage,

Resulting in kind of meshed network?

In line with the message of Drum it may have more benefits to dedicate the Raspberry4 for 'real work', and convert another 'less capable' processor into a NAS-Driver.

MQTT keeps the connection open (unless the connection is really bad)

Question for understanding 'what-if'
How to combine MQTT with Sleep-mode (in which the ESP periodically on purpose closes the connection)?

@TDer Exactly my reasoning to change the WiFi-repeater to cabled WAP: - repeater = 2* Wifi-path, in both paths with 'uncertainty/capacity-limit' related to load & interference + repeat delay - WAP = max. speed cable-transfer + 1*Wifi-path Never sure that the ESP8266 always takes the most direct ...
