TSUN-Gen3-Proxy

A proxy for

TSUN Gen 3 Micro-Inverters

for easy

MQTT/Home-Assistant

integration

# Overview This proxy enables a reliable connection between TSUN third generation inverters and an MQTT broker. With the proxy, you can easily retrieve real-time values such as power, current and daily energy and integrate the inverter into typical home automations. This works even without an internet connection. The optional connection to the TSUN Cloud can be disabled! In detail, the inverter establishes a TCP connection to the TSUN cloud to transmit current measured values every 300 seconds. To be able to forward the measurement data to an MQTT broker, the proxy must be looped into this TCP connection. Through this, the inverter then establishes a connection to the proxy and the proxy establishes another connection to the TSUN Cloud. The transmitted data is interpreted by the proxy and then passed on to both the TSUN Cloud and the MQTT broker. The connection to the TSUN Cloud is optional and can be switched off in the configuration (default is on). Then no more data is sent to the Internet, but no more remote updates of firmware and operating parameters (e.g. rated power, grid parameters) are possible. By means of `docker` a simple installation and operation is possible. By using `docker-composer`, a complete stack of proxy, `MQTT-brocker` and `home-assistant` can be started easily. ## ℹ️ This project is not related to the company TSUN. It is a private initiative that aims to connect TSUN inverters with an MQTT broker. There is no support and no warranty from TSUN. ## ```txt ❗An essential requirement is that the proxy can be looped into the connection between the inverter and TSUN Cloud. There are various ways to do this, for example via an DNS host entry or via firewall rules (iptables) in your router. However, depending on the circumstances, not all of them are possible. If you use a Pi-hole, you can also store the host entry in the Pi-hole. ``` ## Features - supports TSUN GEN3 PLUS inverters: TSOL-MS2000, MS1800 and MS1600 - supports TSUN GEN3 inverters: TSOL-MS800, MS700, MS600, MS400, MS350 and MS300 - `MQTT` support - `Home-Assistant` auto-discovery support - Self-sufficient island operation without internet - runs in a non-root Docker Container ## Home Assistant Screenshots Here are some screenshots of how the inverter is displayed in the Home Assistant: ## Requirements - A running Docker engine to host the container - Ability to loop the proxy into the connection between the inverter and the TSUN cloud # Getting Started To run the proxy, you first need to create the image. You can do this quite simply as follows: ```sh docker build https://github.com/s-allius/tsun-gen3-proxy.git#main:app -t tsun-proxy ``` after that you can run the image: ```sh docker run --dns '8.8.8.8' --env 'UID=1000' -p '5005:5005' -p '10000:10000' -v ./config:/home/tsun-proxy/config -v ./log:/home/tsun-proxy/log tsun-proxy ``` You will surely see a message that the configuration file was not found. So that we can create this without admin rights, the `uid` must still be adapted. To do this, simply stop the proxy with ctrl-c and use the `id` command to determine your own UserId: ```sh % id uid=1050(sallius) gid=20(staff) ... ``` With this information we can customize the `docker run`` statement: ```sh docker run --dns '8.8.8.8' --env 'UID=1050' -p '5005:5005' -p '10000:10000' -v ./config:/home/tsun-proxy/config -v ./log:/home/tsun-proxy/log tsun-proxy ``` # Configuration The Docker container does not require any special configuration. On the host, two directories (for log files and for config files) must be mapped. If necessary, the UID of the proxy process can be adjusted, which is also the owner of the log and configuration files. The proxy can be configured via the file 'config.toml'. When the proxy is started, a file 'config.example.toml' is copied into the config directory. This file shows all possible parameters and their default values. Changes in the example file itself are not evaluated. To configure the proxy, the config.example.toml file should be renamed to config.toml. After that the corresponding values can be adjusted. To load the new configuration, the proxy must be restarted. ## Proxy Configuration The configration uses the TOML format, which aims to be easy to read due to obvious semantics. You find more details here: ```toml # configuration for tsun cloud for 'GEN3' inverters tsun.enabled = true # false: disables connecting to the tsun cloud, and avoids updates tsun.host = 'logger.talent-monitoring.com' tsun.port = 5005 # configuration for solarman cloud for 'GEN3 PLUS' inverters solarman.enabled = true # false: disables connecting to the tsun cloud, and avoids updates solarman.host = 'iot.talent-monitoring.com' solarman.port = 10000 # mqtt broker configuration mqtt.host = 'mqtt' # URL or IP address of the mqtt broker mqtt.port = 1883 mqtt.user = '' mqtt.passwd = '' # home-assistant ha.auto_conf_prefix = 'homeassistant' # MQTT prefix for subscribing for homeassistant status updates ha.discovery_prefix = 'homeassistant' # MQTT prefix for discovery topic ha.entity_prefix = 'tsun' # MQTT topic prefix for publishing inverter values ha.proxy_node_id = 'proxy' # MQTT node id, for the proxy_node_id ha.proxy_unique_id = 'P170000000000001' # MQTT unique id, to identify a proxy instance # microinverters inverters.allow_all = false # True: allow inverters, even if we have no inverter mapping # inverter mapping, maps a `serial_no* to a `node_id` and defines an optional `suggested_area` for `home-assistant` # # for each inverter add a block starting with [inverters."<16-digit serial numbeer>"] [inverters."R17xxxxxxxxxxxx1"] node_id = 'inv1' # Optional, MQTT replacement for inverters serial number suggested_area = 'roof' # Optional, suggested installation area for home-assistant pv1 = {type = 'RSM40-8-395M', manufacturer = 'Risen'} # Optional, PV module descr pv2 = {type = 'RSM40-8-395M', manufacturer = 'Risen'} # Optional, PV module descr [inverters."R17xxxxxxxxxxxx2"] node_id = 'inv2' # Optional, MQTT replacement for inverters serial number suggested_area = 'balcony' # Optional, suggested installation area for home-assistant pv1 = {type = 'RSM40-8-405M', manufacturer = 'Risen'} # Optional, PV module descr pv2 = {type = 'RSM40-8-405M', manufacturer = 'Risen'} # Optional, PV module descr [inverters."Y17xxxxxxxxxxxx1"] monitor_sn = 2000000000 # The "Monitoring SN:" can be found on a sticker enclosed with the inverter node_id = 'inv_3' # MQTT replacement for inverters serial number suggested_area = 'garage' # suggested installation place for home-assistant pv1 = {type = 'RSM40-8-410M', manufacturer = 'Risen'} # Optional, PV module descr pv2 = {type = 'RSM40-8-410M', manufacturer = 'Risen'} # Optional, PV module descr pv3 = {type = 'RSM40-8-410M', manufacturer = 'Risen'} # Optional, PV module descr pv4 = {type = 'RSM40-8-410M', manufacturer = 'Risen'} # Optional, PV module descr ``` ## DNS Settings ### Loop the proxy into the connection To include the proxy in the connection between the inverter and the TSUN Cloud, you must adapt the DNS record of *logger.talent-monitoring.com* within the network that your inverter uses. You need a mapping from logger.talent-monitoring.com to the IP address of the host running the Docker engine. The new GEN3 PLUS inverters use a different URL. Here, *iot.talent-monitoring.com* must be redirected. This can be done, for example, by adding a local DNS record to the Pi-hole if you are using it. ### DNS Rebind Protection If you are using a router as local DNS server, the router may have DNS rebind protection that needs to be adjusted. For security reasons, DNS rebind protection blocks DNS queries that refer to an IP address on the local network. If you are using a FRITZ!Box, you can do this in the Network Settings tab under Home Network / Network. Add logger.talent-monitoring.com as a hostname exception in DNS rebind protection. ### DNS server of proxy The proxy itself must use a different DNS server to connect to the TSUN Cloud. If you use the DNS server with the adapted record, you will end up in an endless loop as soon as the proxy tries to send data to the TSUN Cloud. As described above, set a DNS sever in the Docker command or Docker compose file. ### Over The Air (OTA) firmware update Even if the proxy is connected between the inverter and the TSUN Cloud, an OTA update is supported. To do this, the inverter must be able to reach the website in order to download images from there. It must be ensured that this address is not mapped to the proxy! ## Compatibility In the following table you will find an overview of which inverter model has been tested for compatibility with which firmware version. A combination with a red question mark should work, but I have not checked it in detail.

```txt Legend ➖: Firmware not available for this devices ✔️: proxy support testet ❓: proxy support possible but not testet 🚧: Proxy support in preparation ``` ❗The new inverters of the GEN3 Plus generation (e.g. MS-2000) use a completely different protocol for data transmission to the TSUN server. These inverters are supported from proxy version 0.6. The serial numbers of these inverters start with `Y17E` instead of `R17E` If you have one of these combinations with a red question mark, it would be very nice if you could send me a proxy trace so that I can carry out the detailed checks and adjust the device and system tests.
