SmartSolar Relay Remote Control

In the Firmware Changelog for v3.11 under "Improvements" there's a line that says "Add support to relay remote control mode, which allows the user to manually select the relay state."

How does one use this relay remote control mode? Is it accessible via NodeRed?

How to work with different load settings - Node Red? or ....

Dear All

I would like to "play" with some loads when I have available sun and do not wish the MTTP to throttle (idle).

My idea is to send any excess solar to the boiler element (depending on weather, temp, time, SOC, etc) and maybe a circulation pump. I was thinking, if during the day when the house is in "idle" any overrun from the MPPT can be directed to the element. Some sort of IFTTT concept.... if you know what I mean.

How would you go about this? I do not wish to be a burden on anyone, so if you have a good HOW TO START youtube video or ......, I would highly appreciate it as I can try to figure it out on my own.

I also assume that some sort of relay is necessary to activate the load (maybe AC2out is an option)?

I have heard of NodeRed (not sure what it can do or what is necessary) and grafana but as stated I am not sure how to go about this. Do I need HomeAssist? or ..... for the Victron equipment?

I guess in the end, I would like to (almost) go for a smart home approach.

As stated above, any help would be appropriated.

Kind regards

SmartSolar MPPT 100/20 48V missing Load Current option in Node-RED in OS v2.92

I have just updated my 'operational' system from OS v2.80 to V2.92 and Load Current is no longer available in the list of available values in the Victron Node. It is however still present in the VRM displays and Victron Connect



Has anybody else experienced this problem and are there any suggestions on how to get the Load Current data into Node-RED? So far I have checked with dbus-spy and it does not seem to be present on the dbus either.

Obligation passage consuel installations semi-autonomes


Une question ambiguë sur le passage obligatoire ou pas du consuel.

Installation : Multiplus, panneaux solaires, MPPT. Toute la consommation sur le OUT du multiplus, et le réseau public sur IN.

Grâce à node-red, nous programmons le multiplus pour de pas utiliser du tout le réseau public quand le niveau de batterie est suffisant. Dans ce cas, un réseau indépendant est généré et le réseau public n'est pas du tout utilisé (relais IN ouvert dans le multiplus). En cas de batterie faible, le multiplus ferme le relais IN, laisse passer le réseau pour alimenter les consommateurs et recharge les batteries. Il se comporte comme un fil pour alimenter les consommateurs et comme un simple chargeur (il n'a pas le droit d'injecter sur le réseau).

Sur une situation comme ça où l'installation est soit déconnectée du réseau, soit vue comme un consommateur lambda, le passage du consuel reste-t-il obligatoire ?

C'est une question ambiguë car cela dépend de la programmation...

Peut-être que quelqu'un de ce forum s'est déjà posé la question ?

(Une installation 100% déconnectée du réseau ne nécessite pas leur passage)

Merci d'avance,

How to display Solar Charger 30 day history on Node Red Dashboard?

I'm using the Node Red feature in the Large version of venus os and buiding my own FUN Dashboard :) .I'm trying to access the 30-day history that one can see in Venus OS in the corresponding tab of Solarcharger that is connected to VenusGX and show it in some form on the Dashboard, but I can't seem to find the right building block. The Solarcharger block only contains the current value variables.

How to access and display History data with Node Red?
