There is a whole group in the Home Assistant group about using Haier and some other branded mini splits and reverse engineering the protocol to use ESPs and ESPhome to control them. One of my minisplits was a Mexican rebrand of a Haier/GE, with a USB port and spoke the same protocol, so for $15...
From what I seen in programming mine, it’s a RS485 protocol similar to modbus. The ESP8266 are a little larger than a big postage stamp and fit inside the mini split housing, and has wifi built in for over the air updates. The power requirements and size are minimal, so compared to a...
That’s nice. My panel is flush to Sheetrock, but you gave me an idea to use a media cabinet next to it also flush mount, to put it and some other home automation goodies. You run it by itself or pulling the data into Home Assistant and Grafana?
Home assistant has been a steep learning curve, so yeah, but after SmartThings crapped the bed on the custom stuff I had made in it, I had to dive in.
I’m buying an iotawatt for sure, this post just cements it.
With the posts on using the key fob, to clarify for some, you are losing the ability of having a key fob, it’s portability and using it in a permanent soldered wireless “bridge”, probably it being stuck in an enclosure as posted earlier, to allow your inverter to tell the generator to start.
If...
Yes it’s a heat pump. Put it in the room to hunker down in and run on reduced electric when the grid goes out. Keep us cool or warm no matter what.
I was looking at the LG
LA090HYV3
Also I had it swapped. My current one only heats down to 17 F outside temp but this one heats down to -13F...
I put in a mini split and realized I screwed myself by not going with a higher SEER, only heating down to 13 F, when a new one heats down to -17 F at a 1/4 the power of the old one.
When it does connect and Enphase gets my info, what’s some clown (me) with his own solar panel system in the grand scheme of things? I don’t think my information is so special enough to worry myself about what they do with it.
I’ll take precautions but I’m not going to tin-foil hat my way into...
I’m using the Enphase integration available for Home Assistant running on a Raspberry Pi. It pulls in all the inverters, then all the production and consumption data. Then with some tweaking of the UI, I get this screen for use later on a Fire 10 tablet to control and monitor my home.
The data...
Just saw you had Enphase and a Sol-Ark. Which micros do you have and how many? I’ve read about there are concerns due to how the Enphase micros are frequency controlled and if they shift fast enough to turn off and not overcharge the batteries.
Because if they work just fine, I’ve got to move...
Yes please. Because the plan was if they didn’t was to incorporate a contactor that was controlled by state of charge and open when nearly full, disconnecting the AC coupled solar.
This is good news to hear about AC coupled solar. In my plan, I could run this way until I get around to adding some DC coupled solar to add to the reliability. Great posts here.
I have a 3 ton and 4 ton and have frequent power outages. I installed solar and will add batteries later but I never considered having use of either AC unit during an outage, even with soft start.
I installed a mini split in our bedroom to assist with cooling or heating that one room and then...
This is fantastic. But how did you modify the 16K to have a neutral? Was there an available tap that was unused and just needed you to bring it down to the terminal block?
Is it really that simple? Just changes the settings to be split phase US standard and add the neutral and it’s ready?
I know this has been sitting a while but I have built my own system, minus batteries, instead doing an Enphase microinverter system and done it through Oncor.
I cheated a little because I bought it wholesale from a local solar installer, and used their simple line diagram, provided as part of...
Im in the DFW area and are glad to hear about the 15k. PTO was back in September and it’s just panels and microinverters now.
I’ve been looking at adding the 15k and building my own LFP batteries.
System looks great!
I’m guessing this is frequency shifting to shut down the microinverters? From what I’ve seen on here, there isn’t any throttling as in any value from 0-100% but either all on or all off, unless you know something I don’t know.
