Interesting device, but curious whether (& how much) the 'probe' will have a longer life-span than the cheaper 'probe' which I apply for my setup to measure groundhumidity . The URL points to a webpage in Dutch (with my experiences and results), but hopefully the text is simple enough to be unde...

;-) My question at the end of the message was not without reason. A theremin musical instrument reacts to any change in its vicinity: that is an aspect we generally do not like for a measuring device . For a practical realisation for our purpose, it opens a can of worms .......... As you indicate, m...

Perhaps we have to look in different direction than measuring impedance/resistance between 2 poles. An ESP8266 (and also Arduino and Raspberry) has capability as pulse-counter which could be applied as frequency-measuring, by counting incoming pulses per fixed interval. For this application to be fe...

@shardan, 0.7V is the forward voltage applicable for Si-diodes. Ge-diodes go as low as 0.2V But you are right, still (additional) power amplification needed to get over that threshold. The manufacturer of the 'Conrad-sensor' as mentioned in the first message in the other forum suggests a very simple...

Ton_vN

Alternating current would be the solution, but how to find a very simple configuration ..... Has somebody 'dissected' the circuit of the PCB usually supplied with the rain/soil-sensor? Probably working with a DC-current coming from pole1 and measuring the current through pole2. Just brainstorming, c...

Ton_vN

Did not yet install & connect my rain-sensor, but have some experience with the comparable 'fork'-sensor for soil-moisture. The 'fork' is even more susceptible to corrosion, because it continuously is in the moist soil. After 2 months of 'exposure' it looks as shown below and does not function a...

Ton_vN

Aliexpress delivers a very cheap package to be connected to the switch-input of Arduino, Raspberry or ESP8266, or (also) to the analogue-input of those devices.
No solution for corrosion on the electrodes, but a few DIY-pins can do that part of the job, like described earlier.

Ton_vN

Triggered by your link-hint, I further searched AliExpress and found versions with even bigger 1.3"-screens & SSD1306-compatibility But 3 aspects pop up which require further investigation: - P&P-charge to Europe is surprisingly high for this component (Euro28 or even higher, for 'lot')...

The Wemos-plugon-OLED is nice, but my family complains about readability (due to the small characters at the 0.66"-screen) .........
Any experience with a larger size OLED directly compatible with ESPEasy?

Ton_vN

To get a 'standard' output to Domoticz, the 2 formulae in ESPEasy need to be corrected for the number of pulses per kWh coming out of the S0-interface, because kWh-meters exist with rates different from the 'nominal' S0-value of 1000pulses/kWh. Examples known with pulse-output as low as 1/kWh (SDM12...

Related to DST.

My version is R146, at this moment just for experiments, not yet for 'serious' application.

Apperently need to upgrade ......

Ton_vN

My 'problem' is that the DST-box has been checked, but the extra hour is not added!
Local manipulation of time-offset should not be required to get the difference between Wintertime and Summertime.

Ton_vN

At installation of the 'Mega-firmware' I have checked the box for DST, but starting 25th of March I don't see the expected 1hour-shift in time:
display in ESPEasy of Systemtime is still 'wintertime'.
Any additional action required, or need to wait a while till the default NTP-server switches time?

Ton_vN

Indeed a max. measurement for illumination level of approx. 50klux is some limitation. But on the other hand, what is the practical difference between 'much light' and 'very much light'? ;-) The plants don't care, just the owner ....... If it is not possible to electronically expand the measurement ...

Ton_vN

;-) Just an idea: what happens if you fit an extra pull-up resistor from VCC to D4, to assure that the data-wire of the DHT-sensor gets enough VCC-supply? Another possible practical solution when using DHT-shield. You cannot easily change the Wemos-pcbs, but instead of a pin or socket at D4 of the D...

Ton_vN

Just own (confusing) experience with the Relais-shield on WemosD1: the shields apply a specific interface-pin (hard-wired on the pcb) for data-control. Which interface-pin is used by the DHT-shield for the data-communication to the processor? Is it really D4/GPIO2 as shown in the screenshot in the q...

Ton_vN

@Deennoo The 'fork'-moisture sensor is 'not the most accurate' device, and therefore the resulting values should be believed with "some" (=wide) margin. Let's assume 1024 as 'bone dry'= 0% Humidity and approx. 550 as 'wet' = 100% humidity => range 0% to 100% is roughly equivalent to approx...

Applying an SSD1306 OLED-shield on an ESP8266, type Wemos_D1, displaying 6 lines of 8 characters at display-size = 64*48. Small, but sufficient for some elementary display facilities. 'Local' functional connection to DHT22 is one realization. 'Remote' upload from Domoticz is another side: a basic lu...

See it nowhere (specificly) mentioned for inclusion in the next stable release:
UV/IR/Light-sensor type SI1145 included in the next release, or implementation to be continued by the ino-file?

Ton_vN

@Toffel969 Perhaps kicking an open door, but do you apply for coverage of your premises 1 single Wifi-AP, or multiple APs, or 1*AP+repeaters? Have the own experience that for a setup with physically wide-spread ESP8266s, 1 single AP/router is hardly sufficient to cover the premises. Only the 2 other...

This thread triggered me to explore the following configuration around a PV-inverter which has no local display-panel and cooling only by natural flow. A kWh-meter checks the 230V-AC-output from a PV-inverter: a) connect the RS485-interface from the kWh-meter to the RS485-bus controlled by a Raspber...

My DHT11 is only showning temperature in full degree's nothing in decimals. Where are you looking? Assuming that DHT22 is treated same as DHT11, I see in ESPEasy the DHT-values with 2 decimals, and in Domoticz the Temperature-value with 1 decimal, and the Humidity-value without decimal (but who car...

Thanks for the hint!

(Having some problems with humidity) to measure the moisture content in the bottom under the house, I fitted a 'fork'-probe, as shown at http://www.vannwnhzn.nl/esp8266a2_humtemp02.html Analogue output from the prob's circuitboard to A0 of an ESP8266 WemosD1Pro, running ESPEasy (stable release R120)...

Why the effort to suppress a value at the transmit side?
You have the much easier option to not-use the undesired value at the receiving side.

Setup of ESPEasy with 1*DS18B20 is no problem, and already in operation Expansion to 2nd till n-th DS18B20 is the question ....... ;-) Standing before the realization not knowing how to do. ;-) Probably afterwards very obvious ......

@maluko Thanks for confirmation that a chain is possible. Then at least hardware interface is simple: select 1 GPIO for connection of the whole chain. But software-side seems different: how to use 1 setup-window for multiple DS18B20s against multiple IDXes? Or phrased differently: when setting up, w...

Ton_vN

DS18B20 can be operated in chains. The wiki for ESPEasy describes the setup with a single DS18B20 [although the shown settings-window is for a counter-setup]. That wiki-section also hints at the application of multiple DS18B20s. Underlying aspects such as multiple IDXes as required to funnel the inf...

Ton_vN

Thanks! ;-) Just starting application of ESP8266s with ESPEasy, and therefore committed to the latest stable release R120. Once I have more experience will go for the beta-releases. Related Newbie-questions: 1) is somewhere a survey of the changes per release? 2) the wiki-page tells that installing ...

My Domotics-configuration has 2 Raspberries-with-Domoticz as controllers at the same LAN, of which one is a Raspberry3 having Wifi, as well as some ESP8266s. With the present firmware you have to choose which controller is selected and hooked to LAN or to Wifi. Although the operation of the ESPs and...

What is present status for the shift of a SI1145-plugin to a Release?

Ton_vN

The antenna of that deal for Euro 0,70 sure looks less fragile and more suitable for outside/exposed use than the 6 dB-antenna I found. The gain of that 6 dB-antenna is nice, but it should be protected against touching by 'uninstructed users', which means fixed installation inside a box, with relate...

Ton_vN

Some further search revealed that the required cable seems a transition from IPX (or IPEX) to SMA.
Found this offer as cheapest.

For slightly more money you can buy a complete 6dB-antenna.
Sure suitable for inside application, but how long would such antenna live in an outside environment?

Ton_vN

The D1-Pro from WEMOS has a connector for an external antenna. Very useful, but (in hindsight) I 'overestimated' the dimensions of that (micro)connector. Regardless whether I can find a compatible connector, it is most probable that soldering of such connector is beyond my skill-level. Looked around...

;-) RS485 may be the better way to read-out a kWh-meter, but almost every kWh-meter has an S0-interface 'inviting/challenging' to be used. Have 5 kWh-meters with their S0-interfaces now linked to a K8055-board @ PC and to an S0PulseCountingModule @ Domoticz. The K8055-board operates flawless for rea...

Ton_vN

@ILoveIOT ;-) You could start with a 'reverse' approach: first apply the S0-interface with a counter-interface/-software on ESP8266, until you sufficiently have developed/adapted/tested the interface for the RS485-interface. Once the RS485-interface is up & running, the S0-interface is useful ba...

Ton_vN

The main advantage of a kWh-meter with RS485-interface is that the measurement of all parameters is realised immediately at the incoming 230V-interface, and this type of kWh-meters not only determines the actual power, but also other parameters like accumulated energy, voltage, current and frequency...

Ton_vN

Implementation as described in the Tweakers-link is similar to using ESP8266 as pulse-counter. ;-) In line with your argumentation would then prefer ESP8266 connected to the S0-interface of the kWh-meter, and in your case for SDM230 then the pulse-output with highest rate/kWh to get the best resolut...

Ton_vN

Why a 'heavy' 100A&MID SDM230? Type SDM120C perhaps sufficient for lower load and non-MID? Application of the S0-interface should not be difficult if you configure a port of the ESP8266 as a counter. Comparable meter Type DDS238-1ZN also available at AliExpress. Why RS485-interface & Domotic...

Looking for a similar setup with D1-WeMOS as processor.
Summary of my findings for sensors available through AliExpress.

Any significant differences between BME280 and BME680?

Same or compatible interface would be nice for implementation in ESPEasy etc.

Ton_vN

The ESP8266 is often powered through it's USB-interface. Easy enough, but for meteo-measurement you would like to install the ESP with the sensor set remote from any AC-Power Supply. That calls for a stand-alone power supply. Batteries are a solution: 2 or 3 AA-bateries can do the job, dependent on ...

;-) Indeed, my 2 ESPs are happily humming at version R120. Following costo's explanation I will keep them in that state until I see other reasons for an upgrade of the firmware. To operate the BH1750s more or less within their effective range, it looks that an 'external' attenuation has to be applie...

Ton_vN

Just a guess, to be checked:
for the temperatures and for the switches coming from the ESPs, do you really apply completely separate names/indexes/topics in HomeAssistent?
If there is any overlap, you can expect collisions.

Ton_vN

TLS2561-breakout-boards also have an address-pin to set I2C-addresses 0x39, 0x29, 0x49, selectable with jumpers:
0x29 = pin to GND
0x39 = floating pin
0x49 = pin to VCC

One ESP8266 in operation, with 2*BH1750 and 1*DHT11. The data sheet for BH1750 tells that at 30 degrees from the Line-of-Sight the sensitivity drops to 80% and at approx. 40 degrees to 60%. In order to cover in a clean way the full arc of the sun's movement, the 2 sensors have been aimed with a hori...

Thanks for the hint to the URL: german text is no problem. Considering the cost, effort & risc, perhaps easier to purchase WeMOS_D1_Pro for those spot (s) with weak wifi coverage, and apply the original WeMOS_D1s for other jobs closer to the WAP(s). Or (as alternative) relocate the WAP(s) and/or...

Ton_vN

WeMOS_D1_Pro has a connector for an external antenna, which seems a real bonus to get max. range.
Anyone with a proven idea how to make a simple upgrade for the 'original'/existing WeMOS_D1 to connect an external antenna?
