Zigbee2MQTT vs deCONZ and Phoscon

created: 2022-05-09 from Bernhard

Both Phoscon and Zigbee2MQTT are programs for controlling a Zigbee gateway, like the Conbee 2. The primary task of a Zigbee gateway is to connect and centrally control Zigbee devices. After initial difficulties with stability, Phoscon worked relatively well for me recently, but after more than a year of deCONZ and Phoscon I switched to Zigbee2MQTT.One reason for the change was a dimmer switch, which I did not get stable under Phoscon until last: Sometimes it worked, sometimes not, see also: Conb... ... continue reading

MQTT - Broker in Docker

created: 2022-05-06 from Bernhard

MQTT (Message Queuing Telemetry Transport) is an open network protocol for transmitting messages between devices. An MQTT broker, like the open source Mosquitto server, is a simple solution to receive data from SmartHome devices or to control them .As an example, I use MQTT with an ESP32 microcontroller to have it send values to the MQTT broker, which can be retrieved via the MQTT integration in HomeAssistant. In addition, I use the MQTTBroker to communicate my Zigbee devices via Zigbee2MQT, see... ... continue reading

Since my heating system, a water-to-water heat pump, does not offer the possibility to measure or record the water flow of the primary water circuit, I could not estimate whether enough water is being pumped from the extraction well.In addition to having to keeprecords of the flow rate for approval of the system , knowing the water flow rate for this type of system is essential for potential fault diagnosis. In order to keep a better eye on the primary circuit as a potential source of error, I... ... continue reading

I have not had much to do with Arduino or microcontrollers, apart from updating and operating my 3D printer. Microcontrollers, for example the ESP32, offer a cheap alternative to the Raspberry Pi for certain purposes, such as collecting data or certain control or monitoring tasks: WLAN and Bluetooth included. After entering new territory for me here, I wanted to share my experience from a beginner's point of view. Background of my efforts was a concrete use case. ... continue reading
