I forked your fork. 
I added the Alarm code, and made a few other adjustments. Unfortunately I didnāt have time to fix the Temperature C/F and reverted it back F for my purposes.

Great job!
my HeaterMeter was broken. just got it fixed a couple of weeks ago. so zero progress from my side.
The change from āCā to āFā is mostly cosmetic, as the API use the absolute numbers.
removing the user/password break the support for older (or not up-to-date) HeatMeters. as it doesnāt harm anything, I think its good practice to support backwards if possible.
I hope that I can get back to adding the missing features soon - Iāll merge what i can from your branch when i do.
Just wanted to say thank you!! Works great!! I love the heatermeter.

I implemented automatic temperature unit selection based on āUnit Systemā setting in Configuration\General. Its a bit ugly (most of my code is) but it works.

New features added:
- High/Low Alarm Sensors for each probe.
- Added āset_alarmsā service to set probe alarms.
Thereās MQTT support (readonly).
Setting stuff still neds the API.
But we do not need to poll the API when using MQTT 
in configuration.yaml I have this example that works.

Do I need to put this under the startup tab in home assistant? But change the address to my mqtt address and the user/pass to the mqtt user/pass?
This is exciting. Iām trying to add to my HA and when clicking āCheck Configurationā, I get the following, āComponent error: heatermeter - Integration āheatermeterā not found.ā
ledhed-jgh/HAHeaterMeter
Iām using this one and it works for me, but I have 2 and wondering how to get 2 enabled into Home assistant.
You guys have any idea on how to integrate 2 into Home Assistant?
Figured out how to have 2 in there. Just changed the names to heatermeter2ā¦ LOLā¦ Now Iām trying to get the alarms to have a set feature like the Setpoint. i see that i can call the service and change the individual alarmsā¦ alarms: ā-190,-250,-100,-205,-100,-100,-100,-100āā¦ But how do i just expose one alarm instead of doing all 8?
Sorry for the late response, I havenāt had much time lately to work on this integration.
Unfortunately the HeaterMeter API doesnāt provide a method to update an individual alarm value.
Iāve created an Entities Card and am working on a script to read the input numbers and send them to the set_alarms service. The HeaterMeter API interprets negative values as a disabled alarm.

This is exciting, MQTT would be my preference to monitor sensors. I may add a config option that allows you to specify whether you want to use MQTT or API sensors.

I added an automation to update the alarms from the interface in the Native Heatermeter page. So now all is in sync if I update from there.
I was doing it when probe0_temperature changed from Unknown, which basically updated the alarm values when the HM was first turned on after being off for a period of time.
Yours is better since any change to any alarm value will cause an update. Excellent!!!
Do you mind if I add it to the GitHub Readme?
Absolutely!!
