so i started to look for alteritives and found this "https://www.npmjs.com/package/node-red-contrib-gpio"
so i am going to try to use the i2c pins on an arduino to get the data...with johnny 5..
unless there is a better way???
i have 2 esp-nodemcu's 3 esp01 a esp32 and arduino's to work with
Suggestions please..

I've blown more than one Pi over the years, now keeping well clear of GPIO pins unless completely necessary
I've had good results over wifi using espeasy and esp8266 12e , just load the firmware then all the setup is done on a web page. So far connected 3 x ds18b20 temperature sensors, a i2c ads1115 voltage sensor and AIS data going in through a serial to TTL convertor. Communicates over MQTT then converted into signalk in openplotter in the MQTT tab. Seems very stable so far. AIS was over UDP. Handy not having to get all the wiring into the Pi, esp8266 aren't exactly expensive and don't pull too much power.
