For reference see these examples of product designs with would work in a small flower pot, but please note these do unfortunately not all use hardware with Zigbee support or have multiprotocol support: Note! To clarify, please understand that I am not looking or asking for a Bluetooth-based solution, as instead, I am specifically looking for a Zigbee-based product or hardware with multiprotocol support. Note! If buy it know "There are “Chinese” and “International” versions available and there is a report that only the “International” works." Since the board has several sensors, it can be used as, for example, an outdoor temperature/humidity sensor by cutting off the soil sensor. There is a public ST DTH available: SmartThingsPublic/spruce-sensor.groovy at master · SmartThingsCommunity/SmartThingsPublic · GitHub. It looks like it just reports temperature and humidity, too, and it probably doesn't do much fancy calculation with the humidity (just seems to round the raw value, though I can't see what that actually is...presumably what the generic driver reports, too). Someone in this thread claims to be using a custom driver from Mike or ihiyardi for the v1 sensor (probably not too different?), but I can't find that anywhere publicly and the poster never responded to someone who asked about it.
The first studies on the spatial variability of soil moisture relied on TDR measurements at a few selected time points and on the topsoil [ 28]. In addition, continuous TDR measurements were restricted to the plot scale due to limited cable lengths (max. 20 m). However, a limited number of time points of spatial soil moisture measurements may not be sufficient to capture the temporal dynamics of spatial soil moisture variability on a larger scale [ 7], to analyze spatial dependence [ 29], and to determine temporal dynamics of spatial soil moisture variability after precipitation events [ 30, 31]. This Tuya Plant Soil Sensor GXM-01 is officially supported in Zigbee2MQTT and ZHA in Home Assistant. To pair it, install a pair of AA batteries and hold the button on the front for ~5sec until the blue LED starts blinking rapidly. Zigbee2MQTT

Soil moisture WSNs have also been used to support unmanned aerial vehicle (UAV) applications for soil moisture mapping [ 102]. For instance, Akbar et al. [ 103] showed that a combined UAV and WSN instrumentation can be used to better capture the soil moisture of a certain area by optimizing the UAV pathway planning. Other studies combined a UAV platform with a WSN to monitor, in real time, important parameters that characterize the growth conditions [ 104] and the thermal stress in vineyards [ 105]. Due to the use of 2.4 GHz low-power radio modules, the range of wireless communication between ZigBee nodes is limited to a few kilometres. Therefore, more recently, the LoRa (Long Range) communication technology has been introduced for long-range, low-power, low-bit-rate wireless communication, enabling larger WSN coverage with power consumption similar to ZigBee by using chirp spread spectrum (CSS) modulation technology [ 46]. This modulation technique maintains the same low power characteristics as standard radio modulation but significantly increases the communication range because it is more robust to interference. As you can see, the boards in the photos are slightly different from the design image. The fact is that this is the first version of the boards, the second was supplemented with the ability to use a ready-made BME280 module since not everyone can cope with sealing the “bare” chip. In addition, a more convenient connector for CC2530 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.
We are currently developing more products related to smart gardening, and I would greatly appreciate your valuable input and suggestions. In the past decade, soil moisture WSNs contributed to several validation activities of satellite missions such as the SMAP (Soil Moisture Active and Passive) or SENTINEL missions by providing reference data [ 18, 98]. In addition, soil moisture data from WSNs were used for the calibration and validation of simultaneous passive/active microwave airborne campaigns in the Rur catchment [ 99, 100] to analyze various radiometer–radar fusion methods for retrieving improved soil moisture data products [ 101] and to develop methods for downscaling SMAP radiometer data [ 17].Soil moisture data from WSN has also proven to be useful for water balance analysis at the catchment scale. For example, using an empirical orthogonal functional analysis, Graf et al. [ 10] were able to show that two underlying soil moisture patterns explain the overall soil water storage variability in a headwater catchment. Using the same WSN data, Wiekenkamp et al. [ 12] compared the spatiotemporal distribution of soil moisture before and after partial deforestation and found that soil moisture in the deforested area was significantly higher compared with the forested part, especially during the summer period. This, in turn, caused an increase in the frequency of high discharge in the first year after the deforestation. In another study, Wiekenkamp et al. [ 11] used soil moisture sensor response times from a WSN to investigate controls on preferential flow at the catchment scale. They found that the spatial occurrence of preferential flow showed no obvious relationship with spatial attributes, such as topographical and soil physicochemical parameters, but was governed mainly by small-scale soil and biological features and local processes. Metzger et al. [ 76] investigated the influence of throughfall variability on soil moisture variability in a forest stand using data from a dense soil moisture WSN and found that soil hydraulic properties were the dominant drivers for spatial soil moisture patterns. As far as I know, Spruce Spoil Moisture sensor by Plaid Systems is the only Zigbee product that you can already buy which matches the description, but that is relatively large and expensive (plus it has an ugly colour and design). though its size and price are probably due to it being fully waterproof as design to outdoor use in your vegetable garden rather than potted plants indoors.
The development of sensor devices with communication capabilities, such as NB-IoT, has been recognized as an essential component of smart agriculture [ 58]. Recently, several NB-IoT-based smart water management platforms for irrigation have been proposed and implemented [ 59, 60, 61, 62]. With the increasing further expansion of the worldwide spatial coverage of NB-IoT, it is anticipated that smart agriculture will also become a feasible cost-effective technical solution for smaller farms [ 63]. Among the first proprietary standards for low-cost mesh networks used for WSNs was ZigBee [ 40]. ZigBee is a set of high-level communication protocols that utilize 2.4 GHz low-power radio modules based on the IEEE 802.15.4 LPWA standard [ 41, 42]. More recently, the ZigBee technology has been further developed into ZigBeePro [ 43] and JenNet [ 44]. Each component of a ZigBee based WSN has a radio module to enable wireless communication. The ZigBee radio modules have several software interfaces that connect the hardware devices (physical layer and peripherals) to the user application. The user has the possibility to control the sensor network and manage the communication between the devices by means of the application support layer (APS) and the application programming interface (API). The routing of data within the network and data transmission is handled by the media access control layer (MAC). This is based on the IEEE 802.15.4 standard and is located on the physical layer (PHY). The PHY layer includes the transceiver as well as the sensors and the power source [ 41]. Finally, the user has the possibility to realize advanced functions (e.g., logging function, sensor driver, etc.) by developing a special user software that configures the sensor network. As it stands I today already have both a large Zigbee Mesh Network and a large Z-Wave Mesh Network, (as well as six WiFi Mesh Access-Points), and while we also have more home automation products that use other technologies I am a bit reluctant to jump on the bandwagon for a single purpose product that would require me to also maintain many BLE gateways as additional appliances as well.In the Home Assistant community forum stanvn mention plans to create new modified hardware for it with more or other features: This is the most battle-tested and useful firmware. It periodically reads all sensors and broadcast them via Bluetooth Low Energy (BLE). It works with Home Assistant + BTHome out of the box. Once added to Zigbee2MQTT, the device is identified as model TS0601_soil and manufacturer _TZE200_myd45weu. Considering it’s a battery operated sensor, it is correctly set as an EndDevice. It exposes the following entities in Home Assistant via Zigbee2MQTT: The device consumes 1.1μA in sleep mode and 26mA at the time of data transfer. During the tests, the device worked for 5 days with a measurement and transmission interval of 1 minute, which did not affect the AAA battery voltage in any way. Taking into account the fact that the device remains operational when the voltage drops to 1.8 volts and the measurement interval is increased to 30 minutes, the batteries will last for several years. 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
