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.

The ‘platform’ for the FEIT ones at costco are really well built. They make the Insteon units look like they were a one off hobby project. That’s the part that has the power circuitry, screw terminals, etc. The wifi module used to be ESP based but they switched about a year ago to a newer BK723 chip, these can be reflashed with a ‘OpenBeken’, which is a newer project that has similar functionality to Tasmota but for these newer chips.

The only downside I’ve seen with these is OpenBeken is not as mature and the units ‘hang’ now and then requiring a power cycle (like 2-4 weeks). I have some of the older ESP based units that are otherwise identical and they never hang, this has been getting better with upgrades so likely will eventually be fixed.

If you are OK with soldering you can buy the ESP controller modules on Amazon for about $1 each and just replace them and run stock Tasmota (you have to unsolder the module to reflash it either way, so its not a big deal to just put a different one on). The module pinout and electrical interface are identical.

I spent the weekend moving scenes, automations, and appdaemon scripts over to node red. I really like it. Its a really nice setup and so far (after a learning curve on how the included FSM module deals with invalid triggers) is much nicer to work with than the built in stuff and python.

The only bits of friction I ran into are likely just unfamiliarity with the right patterns to use:

• Looking up entity names in fields that are not intended as entities (ie: inject node) needs a separate window open on the HA entities search screen; its especially hard to find select entities but that’s more of a naming issue inside HA.
• How on earth do you take a trigger message as input, then just create a whole new message as output (other than writing it as a function node)? The change node has no way to just start with a new message, and the inject node can’t be triggered. In a complex pipeline the message kept building up goop and I just wanted to emit a simple message at the end of it.
• A lot of examples in the built in docs show use of top level message properties other than ‘payload’, and some require it (like Trigger uses the top level ‘delay’ property), but this pattern of using top level properties isn’t well supported in some nodes.

How does nodered integrate with HA? MQTT or tighter?
