I have a Google hub screen conveniently located in my kitchen, and I'm wondering if it can be made to display victron data, like the cerbo screen does?
It would be great if I could say 'hey google, show battery status" and it displays it.
Is this possible, has it been done?
Hi @mfred68.
I've not tested this but pretty sure it would work. You could write node red support to get cerbo data to Google home. Imagine there's nodes for it however using home assistant or openhab as an intermiary system as integrating those system into google will be much easier.
Only down side is Google home support these device types. So you might have to fudge it. ie have battery setup as a dimmer or some other % based device. If there isn't a battery device type. (I couldn't spot one)
HI @mfred68
Node-RED is a flow-based, low-code development tool, it can be installed on cerbo devices. This is explained in a fair bit of detail here:

You can use node red to write all sorts of automations. Node red has "nodes" (think of them like libraries or addons). Victron nodes are installed by default so you can access victron data in node red. You could then install a google home node to send the victron data to google home. (I've never tried this but i imagine it's doable).
The only limitation is the type of devices google supports. Like in this link there isn't a battery device so you might have to repurpose something else which wont be as flawless. ie you send battery data to a dimmer switch device on google side, so it'll still give you percentages just have to make sure you never accidentally change the values via speaking to google (this wont do anything on solar side but will leave the google percentage as wrong until node red next sends the correct info again).
