I can recommend BrulTech. I put in a system (3 GEM’s and a Dashbox logger) to cover 3 full panels (plus water, gas, and temps) about 2 years ago and I’ve been very happy with it.

Quick review: It’s all local and is well documented and open at the integration level - with HA there’s already an integration built in for it out of the box (I recommend getting the latest from github as they are actively developing it). Firmware is proprietary but low level (read sensors, send via serial->ethernet convertor, sleep 5 secs, repeat; configuration UI). Support is technical and high quality, install/setup docs are excellent and give good examples setting up and and configuring the CT’s.

My setup: I have the dashbox set up to proxy the raw GEM data to HA’s Brultech integration which then feeds all the HA power/water/gas/temp features. The GEM’s I have read 32 CT channels each, plus have 8 ‘counter’ inputs (gas, water) and several 1wire bus I/O’s to talk to temperature sensors. They send a data snapshot of all readings every 5 seconds to the logger and to HA (greatly filtered).

The dashbox and 3 GEM’s are on wired ethernet, they also have integrated WIFI as an option. They talk on my local net between each other and the dashbox pushes messages to HA - nothing talks to anything on the internet or needs any connectivity to set up.

The HA integration reads GEM-packets, the dashbox repeats the packets received from the 3 GEM’s to the HA integration in my setup - but you can also skip the dashbox and just point the GEM straight at HA.

Some examples from the data logger dashboards:

Have they finally allowed you to set the alert sound in IOS? My problem with mobile discord is the feeble little ding they deem you are allowed to hear is so quiet even with the phone turned up I don’t hear alerts. There are several complaints in their bugtracker about this going back 7+ years, they seem to want people to miss alerts for some marketing/profit reason.

On other platforms you can overwrite the sound file in the package with a proper alert, but not with the “we’re apple, fu and enjoy it” IOS stuff.

I have a subscription in the US and have been watching Picard and Lower Decks – the few ads I get are their up front spam promoting other shows (I hit reload and the ‘forced’ up front ad switches to the CBS logo and plays in a couple of secs). Another show I watch has a few ads, I think the are trying to see how much they can get away with before people cancel. I bought a year at 1/2 price and I won’t be reupping, its a pretty low value and quality streaming service on all fronts (ads, content, video quality, app/site navigation and player, absolutely no useful technical support if their player or service is glitching, cable company class customer avoidance policies and systems).

The video quality on easynews is also much better should I want to watch more star trek in the future.

How does nodered integrate with HA? MQTT or tighter?
