Homeassistant , hubitat or homey?
I used open hab https://www.openhab.org/ for a while and really liked it but had trouble getting it to work with the ZigBee USB stick I bought. So I switched to home assistant and have been on that for a couple years now. Both are solid. I like HA a lot but the one down side for me is I have to pay the 5 bucks a month or whatever it is for the cloud access to control things when I'm not home. Openhab has instructions to set up your own server for remote access.

How to have truly smart HVAC?
Here's what I did at my house. I don't control based on dew point and I only have one HVAC unit, but you could pull this off with openHAB and Venstar thermostats. Venstar was the only brand I was able to find with a local API to control the thermostat. You can set up rules in openHAB to perform what you'd like. The rule engine is powerful and flexible. I'm not gonna lie. It's probably going to be a lot of heavy lifting to get it going but it's rewarding once you've set it up.

Scheduling My Electricity Usage
While I don't care about the whole carbon boogeyman spectacle I do care about minimising our environmental impact as well as dependency on, well, as many external things as I can. One of those things is electrical power so I put about 14.5 kW worth of solar panels on a barn roof, connected to a 10kW hybrid inverter [2]. Since I don't like external dependencies I do not use the supplier's "cloud-based" management feature (*Fronius Solar Web* for those who care about such details) and disallow the thing access to the 'net. Instead I made my own system based around OpenHAB [1], a bunch of ESP8266 microcontrollers hooked up to things like the utility power meter (which has a handy P1/HAN port just for that purpose), a heat pump, a water heater, a small heater in the feed storage etc. The thing gets hourly electricity prices for today and tomorrow and creates a schedule to enable/disable devices based on demand, price and energy production from the inverter. Once I had everything set up it has worked fine without the need for intervention. This does not yet include the washing machine and dishwasher since these devices do not offer an easily automatised interface and because scheduling their use also depends on what we put in them and when we want them to clean those things. I just check the graphs to decide when to switch them on which works fine, no need for more automation.
Our electricity rates - both use as well as returns for power we deliver to the net - vary by the hour. Using the interface to the utility meter and the inverter I get readings every 10 seconds, the inverter also tells me the net frequency so it is easy to see whether the net is overloaded (frequency clearly below 50 Hz) or oversupplied (clearly above 50 Hz).
[1] ...but I have not yet connected a battery since a) we can sell overproduction and b) batteries are still too expensive. I expect battery prices to go down once enough used electric car batteries enter the market.

Create a subghz file from known data?
For example, rtl_433 has the spec for an X10 sensor say I know what data I want to put where, is there some tool/site I could enter in what the "specifications" of the signal waveform are and the data I want to send as a byte-string or binary-string and it would create a playable .sub file for me?

New Guy: Outdoor Thermostat / automated fan start/stop.
For "outdoor distances" I'd probably stick to something LoRa or 433MHz based. YoLink has quite a few options using the LoRa protocol. I use basic 433Mhz based AcuRite sensors paired with an RTL-SDR dongle connected to a machine running RTL_433, and use Home Assistant to trigger automations and alerts.

Mystery signal?
866-868MHz is SRD/ISM band (in UK/EU). Can be things like energy meters, TPMS, medical devices etc. Try rtl_433 on it.

Problem trying to listen to a Honeywell doorbell (RF 868 Mhz) with RTL-433
I'm trying to add a Honeywell doorbell to Home Assistant by using the RTL-433 GitHub project/program. When I run the program the SDR dongle is detected but it doesn't display anything when I press the doorbell (the image shows what I see after running the program and pressing the doorbell). I have also tried Honeywell Activelink (FSK) aka [116], so I have tried both 115 and 116 decode protocols.
