I do not measure soil moisture, but the speed at which the flower leafs go down. I use laser ranger once an 4 hours and I set up derivative sensor to calculate movement per hour and if it is more than 5mm/hr it sends me Telegram notification. The leafs are BIG, so for smaller flower speed should be less. It works for about three months on battery charge. I also measure battery. If you are interested in esphome yaml it is here: globals: I currently do not own any other soil moisture sensors to be able to compare the readings of this Tuya model GXM-01, to prove or disprove their accuracy. Because of this, I can only make assumptions and observations. Even though no clusters are exposed for moisture calibration in Z2M or ZHA, any offset can be easily set by creating a simple template sensor: template: #Calibrate moisture by +5 - sensor: - name: "Moisture Calibration" unit_of_measurement: "%" value_template: " {{ (states('sensor.soil_moisture') | int + 5)}}" Code language: YAML ( yaml ) Verdict PS: I posted the same question in Home Assistant community forum but got no suggestions there as of yet https://community.home-assistant.io/t/zigbee-flower-sensors-for-soil-moisture-light-temperature-humidity/272803/

Knowledge of soil moisture distribution in landscapes is essential, as soil moisture represents a key variable in many pedological, geomorphological, hydrological, climatological, environmental, and ecohydrological processes. Soil moisture plays an important role in the hydrologic cycle by partitioning precipitation into runoff and infiltration [ 1] and by controlling hydrological fluxes, such as interflow [ 2] and groundwater recharge [ 3]. Soil moisture also has a strong influence on energy fluxes between the land surface and the atmosphere, as well as on evaporation and transpiration fluxes, which makes it a key variable in the Earth’s climate system [ 4]. Recently, Humphrey et al. [ 5] showed that interannual fluctuations in terrestrial water storage strongly affect the terrestrial carbon sink and highlighted the importance of the interactions between the water and carbon cycle. Not much time has passed since the publication of the article about the Zigbee soil moisture sensor on the CC2530 chip, as the second version arrived. In this version, the total number of parts is reduced and the assembly is accordingly simplified. Through the efforts of @anonymass, it turned out that the cc2530 can generate a signal on its GPIOs with a frequency of up to 3 MHz, which is quite enough to exclude an external generator on the TLC555 chip from the circuit. Replacing alkaline batteries with Ni-MH batteries, for example, has a chance to survive the most severe frosts. Unfortunately, I could not disassemble the device further without completely ruining the IP67 rating, which is crucial for this device. It meant prying it open by force, which would have broken the seals on the top and bottom caps and render the product unprotected against moisture. Everything was sealed shut with glue, so there was no getting in without breaking it completely. This data is quite enough to signal the need for watering, as well as, for example, turn on the drip irrigation system in the greenhouse. In Jager’s opinion, there is no need to solder on each BME280 sensor, as it is redundant. Version 2

I use MiFlora sensors. Yes it's BLE but work OK even through walls. I use raspberry Pi Zero W as gateway. Not intuitive but works and pumps data via MQTT to HA. You can also simultaneously use phone app Flower Care. Even if you needs more then one to cover whole area, Pi Zero W is cheap and I believe it will be simpler then building your own sensors. Number of articles on soil moisture, soil sensors, soil sensor networks, and cosmic-ray neutron sensors per year since 1961.

Soil moisture WSNs have evolved significantly in terms of technology in the past two decades and can now cover larger areas with sub-gigahertz communication technologies, such as the LoRa technology, to provide detailed spatiotemporal soil moisture data at the catchment scale. In the past years, WSN data are increasingly used to support the analysis of soil hydrological processes from the field to catchment scale and the validation of remote sensing products, geophysical sensors, and process-based models. In addition, WSNs are now used for real-time management purposes, e.g., the optimization of crop yields through efficient irrigation based on soil moisture information. Here’s a photo of the device in one of my wife’s neglected plants, hopefully this soil sensor helps revive it by reminding her to water it more frequently. Note! If buy it know "There are “Chinese” and “International” versions available and there is a report that only the “International” works."

on an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. See the License Does anyone other than my girlfriend believe that the world could really use a Zigbee based capacitive soil moisture + light (UV or lumen) + temperature and humidity sensor product designed for indoor houseplants home automation as well as look relatively good, is small and inexpensive? This review paper presents recent developments in WSN technology for distributed and real-time sensing of soil moisture from the field to the catchment scale and its application in fundamental and applied environmental research. In addition, we also provide an overview of appropriate sensor techniques used in soil moisture WSN applications, as well as a wide range of soil moisture WSN applications, including examples from hydrological research, remote sensing and geophysics, hydrological modeling, and agricultural management. In this way, interested users are given a complete overview of the potential of soil moisture WSN without getting lost in technical details. Basically what I am looking for is an inexpensive Zigbee-based alternative to “ Xiaomi Mi Flora” (as Xiaomi MiFlora uses Bluetooth/BLE and do not use hardware which can support Zigbee firmware).

It has been reported that the communication delay of NB-IoT technology is generally greater than the delay of LoRa due to the complex air interface scheduling process, which also requires iterations [ 56]. This can have a negative effect on the maintenance intervals of IoT devices because a longer transmission time increases power consumption. On the other hand, it has been shown that NB-IoT provides better transmission performance than LoRaWAN in underwater and underground environments [ 57]. Unless required by applicable law or agreed to in writing, software distributed under the License is distributed If you need more frequent reporting, you can also integrate with the Passive BLE Monitor Integration. The sensor is also supported in this integration and exposes the same entities. Different flora can have very different needs regarding moisture and temperature and for some, maintaining these values within their optimal range is crucial for the survival of the plant. Since the board has several sensors, it can be used as, for example, an outdoor temperature/humidity sensor by cutting off the soil sensor.

It is also possible to calibrate the temperature reading using the exposed cluster in Settings (Specific) and set a temperature precision by up to 3 decimal points. ZHA Also on the board, there is optional wiring of the light sensor, temperature sensor DS18B20 (works up to voltage 2.7 volts ), temperature, humidity and atmospheric pressure sensor BME280 as a separate chip or as a ready-made module.
