i have been working on replacing my INCOMMAND factory system in my fuzion toy hauler with HAS. i have had great success over the last few weeks. i have everything working from the incommand with a few acceptions. First i need a couple more relays coming tomorrow and i will have the awnings working thats the last item to control thats easy. next is i would love any suggestions on how i can monitor the factory tank level sensors and possible monitor my generator hours through HAS. I have a RPI5 running head end. i bought the makerfab 8 relays boards to control everying the in command did. I wired bosch 40a relays between the makerfab relays and the devices. i also added a couple shelly relays to make some lights smart that were not. love to hear suggestions on the tank sensors and if anyone has any other suggestions love to hear them.
How deep are your tanks?
These are available up to 600mm in length and are super simple to interface to an ESPHome ADC input:
i would more like to use the factory sensors getting something installed onto the tanks would be a huge pita.
Do you know what the existing sensors output?
i believe they sense voltage? from what i have read and put together it senses i think 7vdc across ground and the sensors.
I have not posted much on this but after having this for a year I am still tinkering with it. Some of the Major changes is I am now running my HA off of a NUC. two things on that topic. i started this wanting to use a PI5 however i could not seem to find any way to reliably run it off of 12v. I recenlty found this 12v adapter that will run a PI5 however it will also power a TMobile Home Internet Router which is what i am using it for and for the first time i can run my hot spot running down the road.

The other big challenge i have had is really my lack of understanding of my RV’s built in what I thought was a router. i am ashamed to say how long i fought connectivity issues between my tablet or phone and HA. Turns out the built in devices was not a router long story short i just added a Mikrotik AX3 Router that has so drastically improved my reliability. For the longest time I rand my setup on a PI-4 with a external SSD. Some of the other things are i added a zigbee controller however this led to me installing the NUC as the zigbee controller took out my PI-4 because it was to my USB power i am guessing than the PI-4 could hanle with the SSD. i do love the zigbee setup thought i have added a wireless motion that turns on our step lights at night that is so helpful. i also added some ZIGBEE buttons around the camper to turn on lights. i will say i am still not smart enough to get the factory tank sensors to integrate very well with HA so i did just end up putting in one of the factory RV tank sensor monitoring setups because we dont use them enough to really care about that integration the only one we really use is for the fresh water tank. I think that is pretty much all the things i have changed so far.
